The Earth gravity field and ocean circulation satellite put into trial operation

European Space Agency announced on the 20th, the Earth gravity field and satellite ocean circulation (Goce) since launch on the 17th after the satellite control system is operating well at 0:00 on the 20th from the start, the satellite carried out a mode switch, all scientific instruments into the trial operation stage . 

     European Airlines in a press release issued that day said, Goce launched its portable satellite tracking device that is put into operation, the role of this instrument are to receive the Global Navigation Satellite System signals, and its high accuracy, except exert navigation, but also records and satellite orbit adjust. At present, the European aircraft located the Italian Earth Observation Center has received a tracker back to the first signal. In the coming weeks, Goce will complete a series of difficult tasks, such as startup electric ion drive mode and adjust, such as satellite orbit. 

     Goce satellite is launched in Europe in recent years, the Air Board's most advanced satellite to detect one, it weighed about 1 ton, equipped with a number of sets of high sensitivity detection equipment, access to the data will help scientists gain a better understanding of the internal structure of the Earth, on human study of marine and climate change will also be helpful.

Discovery astronauts finish 2nd walk JEM GPS antenna installation

The United States space shuttle "Discovery" at the International Space Station today Astronaut (International Space Station) outside the completion of the second spacewalk for the Japanese Experiment Module "I hope its" installation of GPS (Global Positioning System) antenna, a space station the construction of the final stages of completion. 

     GMT 16:51, Space Station orbiting 354 kilometers above the South Pacific Department of the Earth's orbit, the astronauts Wansen history (Steve Swanson) and Aqaba (Joseph Acaba) begin spacewalk. 

     Astronaut itinerary in accordance with our established, the implementation of the Discovery space walk 3 times in the 2nd operation, the entire process lasted 6 hours and 30 minutes. 

     Space Station yesterday, the successful launch airfoil huge solar panels, for the Earth's orbit on the space lab to do a good job the first time, generating pre-loaded with homework. History and Aqaba Wansen Yan P6 today released two of the batteries for the next mission in June to replace the battery at the time of preparation work. 

     Space Station as well as two of the Japanese Experiment Module "I hope its" global positioning system antenna installation. 

     Global Positioning System-guided Japan's cargo spacecraft will help HTV. The cargo spacecraft will be opened later this year. 

     This spacecraft can hope that its water supply, food and scientific equipment and, if necessary, may also be required for other parts of the supply station. 

     Discovery in Florida on the 15th launched, space station construction mission to implement the final phase of the job. Lasted for more than 10 years of space station construction projects in 16 countries from its birth and up to 100 billion U.S. dollars to spend.

Astronomical feat! Live asteroid hit the Earth

Astronomers detected the first time in the course of an asteroid hit the Earth, but also from its follow-up period is still space to bring it, the last and the collection and analysis of meteorites. This was published in "Nature" the study of scientific journals, not only to allow scientists to know more about the F-type asteroids, and perhaps inspire them to consider how to avoid future occurrence of the tragedy of the Earth into a planet. 

 This 14 meters wide, 83-tonne, about the bus-sized asteroid is arrived at in October last year, 19 hours before the Earth was discovered, astronomers also have an unprecedented opportunity for observation and the final route of projectile scene for the fireball. Similar to the asteroid-sized objects, it is difficult to detect in space, there is 3-4 per year into the Earth. 

 I am astonished that there is some remnants of the asteroid had not completely destroyed during re-entry, but landed in the northern part of Sudan, about 29 kilometers stretch of the Nubian Desert. By December, astronomers mobilized civil 45 University students and teachers line up in the desert meteorite fragments of a search and finally found 280 meteorites weighing from 1. 283 grams to five grams, ranging from a total of about four. 45 kilograms, the whole process is like a needle in a haystack. 

 California, "Institute of search space intelligence" (SETI) astronomers that the probability of follow-up to the Asteroids, "is only one chance of a lifetime." Involved in monitoring this asteroid Belfast Northern Ireland Queen's University professor fee, points out that scientists are now able to predict not only where the asteroid will be rammed, but also early warning, to obtain relevant information immediately. 

 The United States Arizona viewing an amateur, and October 6 last year, reported the coordinates of an asteroid discovered in Cambridge, Massachusetts to the Minor Planet Center. This is just one of hundreds of routine records, but the computer system has the magic to refuse this extra information. Gaspar, director of the center told the "natural": "I see this information and to manually make a track, it is obvious that crashed into the Earth." 

 Asteroids of this size and brightness of the Earth should not pose a risk, but Gaspar safety procedures in accordance with the standards of practice, direct-dial NASA (NASA) hotline. He also reminded the Jet Propulsion Laboratory rationale of Sanchez, who immediately calculate the asteroid orbit. Computer program shows that the probability of an asteroid hit the Earth up to hundred percent, will hit the atmosphere within 13 hours, forces one to two tonnes of TNT equivalent TNT. 

 It was named 2008 TC3, was later renamed . I Tower (Arabic meaning for the station on the 6th)." It is classified as F-type asteroids are very rare types of meteorites. Only one. 3% F is a class of asteroids, formed in 45 billion years ago, with the Earth and other planets about the solar system at the same time. Since then most of the time it at between Mars and Jupiter around the sun outside the asteroid belt running it into a collision of another track, and narrow the gap between the earth, eventually assisted by gravity at the Earth into the Earth onto the road. 

 Stay in the Nubian Desert Station "on the 6th station" and the town of Al-fat people, are said to see the return of "fireball similar to the Rocket." KLM in Africa over the driver, also 2008 TC3 to 12,000 meters per second speed collision the atmosphere, reported that there is to see a bright flash on the ground.

35 million U.S. dollars the United States and rich visit space

5 the world's first "space tourists" ‧ American millionaire Charles Simonyi is scheduled to begin on the 26th his second trip to space, is expected to become the world's first space travel "repeat." Russian Space Management department previously announced, subject to restrictions on the carrying capacity of the international space station, after the cancellation of this year Russia intends to "space tourist" project. This means that temporary Shimoni as possible to the Russian space tourist last at their own expense. 

 The first repeat space travel 

 Shimoni is scheduled on the 26th, accompanied by two professional astronauts from the Baikonur launch site in Kazakhstan launched to the International Space Station. He is expected to remain at the space station less than two weeks, April 7 to take "Union" manned spacecraft to return to the Earth. 

 If the successful completion of the trip, Simonyi will become the world's first space of the two "space tourists." Shimoni finish in April 2007 the first two-week trip to outer space, becoming the world's first self-financed five "space tourists." Shimoni trip that took 25 million U.S. dollars. Media reported that the cost of this trip will be more than 35 million U.S. dollars. 

 Shimoni again for reasons of space travel, the Associated Press quoted him 23 in a telephone interview to answer the report, a number of astronauts in space Shimoni Ending first told him after the tour, once again, "Flying" and the feel with the first harvest is radically different from that space to do his initiation Tour "repeat" of the idea. 

 Finally the tour at their own expense or 

 Russian Federation Space Agency officials said earlier this year, the number of the International Space Station astronauts Permanent probably by the end of May to 6 people, more than doubled in the past. Because of the space station and personnel carriers bearing stress increased after the Russian side intends to cancel this year at their own expense, "space tourists" project. 

 Heard the news, Shimoni decided to seize the "last chance." "Either now (emphasis on space travel), or no (opportunity)." He said. 

 However, even though there are still opportunities for the third space, Shimoni do not intend to have another try. "I am no longer young," the 60-year-old millionaire said that the addition of his new wife has agreed to no longer "three space travel." 

 To help achieve scientific experiments 

 Shimoni put on the first trip as a "sequel." He said that two out of space travel the same purpose, namely "to support space research, universal civil aerospace business, to introduce offspring exciting science and engineering (the outcome)." 

 The Hungarian-American millionaire has a doctorate in computer science and flight license, a former Microsoft software development division, to participate in research and development of software such as Word and Excel. 

 The space trip, the Shimoni intended to assist the completion of a number of medical and technical aspects of radiation experiments, will also use the "Windows on Earth" software for the Earth to take photographs for people to watch.

Microsoft co-operation with NASA to create a virtual telescope

According to foreign media reports on March 25, Microsoft and the U.S. space agency said on March 24 announced the establishment of cooperative relations, the cooperation will allow the software giant telescope of the virtual world (WorldWide Telescope) was the United States and other NASA Mars a large number of photographs of celestial bodies. 

 NASA and Microsoft will jointly develop a system so that the public can come into contact with Mars, the Moon and Other Celestial Bodies, the universe of high-definition photos and scientific information and on-line website at worldwidetelescope.org  to explore the universe. NASA's science mission, deputy director of the Commission ‧ Edie Wheeler (Ed Weiler), said: 『for NASA, the primary problem is to allow the public easier access to U.S. scientific and astronomical information, particularly in the new The Government has recently focused on Chief will govern the case of open and transparent. 』 

 A few years ago, the search engine giant Google and U.S. space agency set up on the co-operation, the U.S. space agency to provide a lot of scientific photographs, to enhance the functions of Google Earth. At this free service provided by Google Earth three-dimensional photographs of Mars, the spacecraft real-time tracking information and a virtual trip to Mars and so on. Microsoft said the U.S. space agency will provide them with more than 100 TB of data, the global web telescope will begin later this year to integrate the information, including the August 2005 launch of the Mars Exploration Orbiter (MRO) photographs from the So far in 2006, scientists have been studying these photos. 

 Microsoft Research is responsible for external affairs vice president, Tony ‧ Hoey (Tony Hey) Say: 『such cooperation will enable people all over the world can be at the rich and interactive environment of the Moon and Mars in detail View the new photos. Want to explore the space and experience the achievements of computer science and computer technology developers, educators and students, the world's most powerful telescope instrument. 』 

 Global Telescope website will soon have  moon orbiter (LRO) photographs. The probe is scheduled to launch in May this year, aims to collect environmental information surface of the moon. Global Telescope website on line a year ago, the integration of ground and space telescope photographs analog observation to the effect of the vastness of the universe. 

 NASA Ames Research Center Director Pete Worden ‧ (Pete Worden), said: 『NASA is excited to work with Microsoft to establish cooperation with students and those who live z owl owl Quan Shu  go together to share their photos massive planet . This is an impressive astronomy resources, help to inspire our next generation to explore the passion of astronomy. 』

New York City Science Fair

By the New York City Department of Education, City University of New York (the City University of New York, referred to as CUNY) jointly organized the American Museum of Natural History, "New York City Science and Engineering Fair" (New York City Science and Engineering Fair) final, 25 Museum of Natural History in the United States held within the exhibition hall of marine biology, a total of 14 events to attract 176 high school students displayed more than 700 topics. The final 20 selected winners will attend on behalf of New York City in May, Nevada (Nevada) Reno (Reno) at the Intel International Science and Technology Competition (Intel International Science and Engineering Fair). Yesterday's exhibition, a total of nearly 40 Watson present, take part in the exhibition are about one-quarter of the total number of students, Watson variety of research projects, brisk performance. 

 Yesterday's exhibition involving 14 categories of subjects, including zoology, behavioral sociology, biochemistry, cell and molecular biology, chemistry, computer science, earth and planetary science, engineering, environmental science, mathematics, medical and health science, microbiology, physics and botany. 

 Klein, director of City Board of Education (Joel I. Klein) said that these students to enter the finals are the future of the United States, President Barack Obama has pointed out a few days ago the scientific, health and medical care is still the country's key projects. Finalist in the 176 has 155 students (90%) from public schools, there is such a good student, parent-teacher should be grateful for their support and help, they are the true heroes. 

Chiang grew up in Fujian this year, 17-year-old, now studying at the Manhattan International High School (Manhattan International HS) 11 years, he take part in the exhibition are Watson yesterday to the United States in a shortest time. Entries belong to him the subject areas of biochemistry, research topics for the "DNA on the treatment of diabetes." 

Chiang at Columbia University, a laboratory, he said that the initial idea of the experiment by Professor Milan N. Stojanavic suggested that he was at two under the guidance of the instructor, independent completion of the experiment. 

 Talking about his own life four years the United States,Chiang said: "Today can be in the forefront of this final meeting, most of the parents to thank my encouragement, to thank the United States at the beginning of my assist teachers and students."Chiang father from Shanghai, the mother from Fujian, immigration to the United States, the father cooks in restaurants, the mother opened a video shop, on the whole town lived in Manhattan. After the first Chiang to the United States to study at secondary school on the city of Wagner, he did not remember that a Chinese class, usually beginning two years of his cram school go learn English, but all classmates to help him, let him be able to relax at the Education and study mode. 

Chiang said that parents found him to study as long as their efforts are allowed to dream come true. Parents work hard, even though first-generation immigrants, as English is not good, but they do not give up on their own hard work to create a happy life.

Melbourne 4.6 Richter scale earthquake happened more than 10 years rare

The history of Australia has just experienced the most serious forest fires in Victoria, Australia, on the 6th night also happened the past 10 years the largest earthquakes, although no serious damage, but the Melbourne metropolitan area because the building shaking people are very frightened. 

 Responsible for carrying out observation and prediction of seismic activity of the Center for Science in the Earth Australia (Geoscience Australia) pointed out that this 's seismic intensity scale of 4.6, epicenter located in south-east of Melbourne, 90 kilometers Area (Korumburra). 

 Center for Science in the Earth Australia said that after the earthquake, the Center's Media Center and the Australian Bureau of Meteorology are receiving a large number of people concerned about the phone; However, Victoria's emergency ambulance service organizations, so far, apart from sporadic reports of residential damage, and there were no reports of any serious damage. 

 Center for Science in the Earth Australia staff Schneider (John Schneider) said that it was following the 1996 Melbourne region 5 on the Richter scale earthquake, the local felt earthquakes uncommon.

The United States lost carbon olfactory satellite

The United States first used to detect atmospheric carbon dioxide content of the Earth and its satellite distribution map drawn on the 24th due to launch failures and crashed into the sea near the Antarctic 

 According to Xinhua News Agency, the United States's first electric specific detection of the Earth and atmospheric carbon dioxide concentration of greenhouse gases for such a comprehensive distribution map drawn on the 24th satellite launch failure due to fall into the sea near the Antarctic. 

 The United States National Aeronautics and Space Administration (NASA) said that the launch in-orbit  Carbon Observer (OCO), that is odorless carbon  satellite preparation period of up to 8 years, the satellite crashed the relevant personnel of depression. 

 It is learned that NASA will set up a special committee to investigate olfactory  carbon causes of the failure of satellite launching. 

 Separation failure 

 The Associated Press reports, This is NASA since September 2001 the first time since launching a major failure of mission. The entire satellite project cost 280 million U.S. dollars. 

 NASA launch director Chuck ‧ Sandoval described the failure of the scientific community extremely disappointed. 

 In accordance with the United States "New York Times" that  Taurus XL rocket's third grade seven seconds after ignition, the rocket fairing the front of the failure isolation and arrows, with the result that is located under the fairing of the satellite can not be released into space. 

 Agence France-Presse reported, this is the first time for NASA to launch satellites using Taurus rocket.  Olfactory carbon project manager Brenton Wheeler Shi say that in the past to launch the process of fairing has never been a problem. 

 Worse 

 According to NASA official website introduction, scientists had looked forward to using the thinner carbon 』satellite to collect information to help answer a series of questions, including the location of emission sources of carbon dioxide emissions, such as geographical distribution. 

 Carbon  olfactory satellite hence the name. Its failure to make full z American scientific community criticized the efforts of NASA Earth observation also casts a shadow. 

 The United States National Academy of Sciences in 2007 warned that the Earth NASA research project has been in danger  to study less and less ad hoc, the gradual aging of the relevant satellite. 

 This month, U.S. President Barack Obama ‧ economic stimulus plan put in 400 million U.S. dollars for NASA scientific research project. The Associated Press quoted NASA Science Department is responsible for weiler person as saying: 『money all u _ Bali earth science research. 』 

 Members of the National Academy of Sciences, Columbia University Professor Ruth ‧ de Vries said: 『very sorry, when we are trying to push back on track when the Earth observation, but the accident happened. 』 

 NASA used to study under a climate change satellite  honor its launch scheduled for this summer, but this program will be thinner carbon  investigate the causes of the accident have been suspended before. 

 Copy the satellite? 

 The Associated Press reported that carbon  olfactory satellite launch fails, NASA is facing a problem is to not to recycling, or copy a thinner carbon . 

  Olfactory carbon members of a special team of Colorado State University, USA Professor Graeme Stephens ‧ that many members of task force is urging NASA to do so. 

 Will have serious impact on climate research 

 On the 24th, the United States carbon  olfactory satellite due to launch vehicle failures in the Antarctic waters near the crash, which French climate experts believe that the accident will cause serious impact on climate research. 

 United Nations Intergovernmental Panel on Climate Change, vice chairman of France Jean ‧ Joinet Purcell told the media that if the carbon  olfactory satellite successfully launched, it can be launched in January this year, Japan's greenhouse gas satellites simultaneously No.  breathing observations of atmospheric carbon dioxide, for climate scientists to provide the overall greenhouse gas distribution and monitoring the process of change, therefore, the failure of the launch will result in related research is very adversely affected. 

 French research center on Climate Science Laboratory experts on the 26th Peter ‧ Reyna pointed out that although the respiratory  launch filled the southern hemisphere oceans and tropical regions of Africa a blank observation of greenhouse gases, but its observation capabilities and the scope of carbon thinner than .

Hong Kong and the United States Institute scholars measured glaciers 3400 years ago the climate

Antarctic ago, originally was not world of ice and snow, but due to climate change, the moment has become a frozen desert. Department of Earth Sciences, University of Hong Kong assistant professor Liu Zhonghui, United America, Yale University, Harvard University and several other scholars in conducting research are leading to global cooling at that time the rapid expansion of Antarctic glaciers of important reasons, the study will be more up-to-date authoritative journal "Science" ( Science) published. 

 Served in the Department of geology and geophysics at Yale University, last year joined the University of Hong Kong Liu Hui for the thesis of the first author of the study in the United States two years ago by the National Natural Science Foundation and Yale University was financed, he and Mark Pagani, Yale University scholar and David Zinniker, Harvard University, Sunita R. Shah and Ann Pearson number of scholars, such as cooperative research. 

 Zhonghui Liu said that before temperature data, there is no record of the study are the biggest obstacle, so they are organic compounds in marine sediments through the distribution of characteristics, then the projection of global sea surface temperature and found that at the time of the high latitudes temperature, than previous studies estimated temperature, higher than at least ten degrees Celsius, while the glacier expansion in the process of sea surface temperature, but also significantly reduced by about five degrees Celsius. 

 He also said that, at present, computer technology is still difficult to accurately project the Earth's greenhouse climate change, because of system is mainly to adjust the content of carbon dioxide projections, should be added to other factors, trust can be a more accurate result.

Kepler earth can not alone for us to look for a special planet

March 5, United States Air 

 Days Board (NASA) will launch the Kepler spacecraft to complete the first category to look for extrasolar habitable planets mission. 

     According to the schedule, the evening of March 5, local time 22:48 (GMT at 3:48 on March 6), Kepler -2 detectors will be aboard the Delta launch vehicle, from the United States is located in southeastern Florida Florida's Cape Canaveral launch. 

     This is the United States Space Agency arrangements designed to look for the first time, type of mission to rock the planet, NASA Kepler detectors are available for the discovery of planets similar to Earth's environment a key factor in the efforts. 

     The number of extrasolar planet? Almost no answer until now because of the current astronomical observations are not sufficient to detect these "special" planet. 

     However, with the March 5, 2009 the United States Space Agency (NASA) Kepler Space Telescope into space, we will be behind these "special" Planet of the veil. 

     The original methods of observation flawed 

     "We all hope that many of these planets exist," "Kepler," the Chief Scientist, NASA Ames Research Center Lucky (William Borucki) said, "If there is lot of extrasolar Earth's existence, then you may have a lot of lives. there is perhaps even extraterrestrial civilization is waiting for us and their contact. " 

     By ground-based telescopes on the observation of gravitational lensing, and in 2006 launched the "coronation" extraterrestrial planetary probes of planetary observation Ling stars have been found two slightly larger than the Earth extrasolar planets. The two rocks may be composed of the quality of the planets around the Earth several times, all around the red dwarf star Gliese 581 rotation. Both have at least a Livable zone is located, but very close to the edge of Livable belt, it is still difficult to determine their surface if there is any liquid water exist. 

     The crux of the matter found that the current method of planets. Most of the extrasolar planets are through "Velocity" method was found, through looking for stellar spectra may be due to the planet's gravitational effects arising from the cyclical nature of sports signals to detect them. However this method is the quality of the Earth and similar planets are not sensitive to low-quality. 

     Two major advantages, more sensitive observations 

     "Kepler" is designed to look for these "lost" world. It through the monitoring of more than 100,000 stars of the cyclical changes in brightness, will be able to appear in the stars and planets, "Kepler" between the time to discover it. 

     "Kepler" will be far away from the Earth's orbit around the sun turning in order to avoid interference from the Earth Observing it. This makes it at three and a half years uninterrupted observation area with one days. In contrast, "coronation" is rotating around the Earth, the Earth will be blocked so it's attention. At the same time in order to avoid the effects of sunlight on the observation, so "coronation" of the district with the longest one days duration was only five months of continuous observation. 

     Because of the monitoring objectives can be a long time, "Kepler" at least three times to see a one-year orbit cycle of Planet Ling stars. This is to confirm these cyclical case Strict observation for at least the required number, which can rule out the brightness of stars such as interfering factors such as their own fluctuation. 

     At the same time, "Kepler" will than the "coronation" is much more sensitive. Its effective diameter of 95 centimeters, are "coronation" of 3.5 times. This makes the size of it can be seen only half of the Earth, and Mars is almost big planet. 

     Telescope twice a week contact 

     Stonehenge from the University of Colorado City Campus Laboratory of Atmospheric and Space Physics (LASP) of 20 students and 16 groups of experts, will study at the University of Colorado LASP Space Technology Park manipulation Kepler telescope building at Florida Cape Canaveral launch. 

     LASP mission operation and data analysis director said that the University of Colorado at boulder City Campus mission operations team is the co-operation and Bell companies. Bell created a Kepler telescope --- the main components of a one meter diameter Large Telescope and many photosensitive microchip as well as the Kepler telescope flight systems and the operation of this mission to support the work. 

     Once the Kepler telescope, enter the stage of planet hunting, LASP Kepler mission control team will contact this week, the two telescopes to monitor the above with the apparatus, including sensors, battery positioning control system, voltage and temperature as well as load instruction. Possehl said that the telescope will be so point to the Earth once per month, the data "dump" to the United States Space Agency are located in the Earth near the equator of the deep space network, and then, these data will be transferred to the University of Colorado boulder City Campus Atmospheric and Space Physics Laboratory, the transmission will continue to work sometimes 36-48 hours. 

     Then, LASP these data to the United States Academy of Sciences, Baltimore, Space Telescope, and then by the NASA Ames Research Center of the scientific analysis of data. 

     Look forward to, "Kepler," respondents 

     No one knows, "Kepler," able to detect the number of stars and planets similar to earth, but found substantial and Jupiter-sized extrasolar planets should be not to mention the. Around 15%% of the category of solar-type stars will have planets wood. Jupiter necessary because of the formation of many substances, so said: "We consider the formation of Jupiter than in many rare earth." 

     No matter, "Kepler" discovered what would make detection of extrasolar planets into the next era. If terrestrial planets are ubiquitous, so future plans will be examined in detail whether one of aerobic existence and life, as well as other relevant evidence.

NASA and the European Space Agency (ESA) are separately assess the "terrestrial planet finder" and "Darwin" program, which plans to launch in 2020 for the observation of stars is located in zone Livable planet. One of the main objectives of those who are observing the planet through the atmosphere light spectrum, in order to find and life-related chemical composition of oxygen and other signals. 

     Finally whether these plans will succeed depends entirely on the "Kepler." If eventually found terrestrial planets are ubiquitous, so in the next 15 years will certainly set off a careful study of these planets boom. However, if the "Kepler" Livable finally found with the terrestrial planets are very rare, then our observation can be at the limits of its resources may not fit the objectives of our research. The detection of terrestrial planets more distant plans, not only technically there are still a lot of obstacles, but also necessary to take a long time. 

     Now history, at least give us a chance to know extrasolar terrestrial planets are are rare. Ever since Copernicus put the Earth from the pull down the center of the universe after the Earth's position in the universe "deteriorating." But the Earth is one of the many planets in one, and in the discovery of hundreds of stars planets around other stars also appear after the solar system is not so special. 

     Whether the prevalence of the universe, the size and characteristics of both the Earth and similar planets? "Kepler" will answer for us.

     Europe's "coronation" extraterrestrial planetary probe 

     In the "Kepler" space telescope is focused on the discovery of the first extrasolar terrestrial planets real time, and should not be forgotten that previous plans. French construction of the "coronation" extraterrestrial planets discovered so far detector the smallest extrasolar planets. 

     Distance of 390 light-years distant, we Exo7b are the diameter of the Earth twice. Although it does not know exactly the quality and composition, but its density and the type of rock similar to terrestrial planets. 

     Its orbit is very close to the star, the public switch to cycle only 20 hours, are known to the public and to the planet's fastest. Its surface temperature is over 1000 ℃, can not carry life, but in this system is also very likely have other planets exist. 

     Benefited from the detailed design process and, of course, some luck, "coronation" performance beyond the expected. In the "coronation" of the data back hair and several hundred others left to interesting signals of large-scale follow-up to the observation and study of ground-based telescopes. 

     "Coronation" of the findings support the existence near the earth extrasolar terrestrial planets of the mind, which "Kepler" is concerned is good news. And "Kepler" may be able to find more other earth.

Heated debate between scientists and experts in civil seismic line

Chinese Seismic Network Center Chief Forecaster Sun Hung: 

I hope there is a smooth communication channels 

『Still a lot of people from the celestial bodies to study the seismic point of view. Not long ago, a person came from Wuhan, get this book and I want to explore the celestial bodies and the relationship between seismic. I said, already has several people holding this view, several people also out of the book, I suggest you a few people together to discuss the issue. 』Sun Hung said. 

Since the proof of one plus two, after a lot of people every year to the math by writing letters, claiming to solve the 1 +1 = 2 problem, this letter, the Chinese Academy of Sciences Mathematics close two sacks each year. 

『Li Wei also said that normally the data collected is very limited information, thus limiting the level of research. If instead of "Beijing Science and Technology reported that" provide a platform, never thought of seismic experts can communicate with. 』Sun Hung says, these people, although the level of science enthusiasts have been mixed, in which these scientific enthusiasts, there is a lot of people's views are very innovative. While they may in a particular area of research is not bad than the experts, some even more solid. If we can take full advantage of their research, give play to their enthusiasm for the work of the Academy of Sciences will provide a lot of help. 

Channels do not communicate because of smooth, easy to a lot of civil science enthusiasts and experts of the Academy of Sciences by the formation of a misunderstanding. Sun Hung said that the drought appears, give us call on someone. I received such a phone call asking: Why do not you study the drought? But they do not understand, according to our research, climate and seismic vs at the relationship between, not the impacts of climate change activities in the Earth, but the activities of the Earth affect the climate. How do we communicate? 

Sun Hung said that a lot of experts are experienced by non-governmental science lovers plugging things in the office. I now have a large part of the time  exposure to these civil science enthusiasts on. However, a person's ability to me was really very limited, and as a scientific worker, out of time to be able to make these things very few people again, I would like to be able to have a smooth flow of communication channels. 

Popular Science, Fuzhou, Japan, in the magical joy  dock, the computer system in accordance with the viewer's hand video will appear on the screen image of the corresponding animal 

Non-mainstream, grassroots science destiny? 

『Civil science enthusiasts to small inventors, small innovative start, select some of the knowledge do not ask for much, the program is not strong disciplines, such as natural history, and some new species is discovered amateur plant enthusiasts. 』 

Beijing Planetarium Hoi Wing, deputy director of the King told "Beijing Science and Technology reported that" a lot of civil science enthusiasts are without solid foundation, before the knowledge and study the work and carry out scientific research is not relevant to the project. Because they are not professional scientists and technicians have received systematic and standardized education subject knowledge, as well as the basic formal scientific training, and so in civil science enthusiasts in the area of concern is often not a solid foundation of knowledge. 

The mathematics and science often requires the accumulation of knowledge step by step. Such as primary school after graduation can be up, after graduating from middle school to college can be. Only by virtue of the mathematical knowledge of primary and secondary schools are unable to verify the Goldbach conjecture; only school of physical knowledge, can not open the gate theory of relativity. The research is not a solid foundation of knowledge, will hold back scientific research. 

China University of Geosciences think Jin-Zhong Sun, for lovers of civil science and scientific research in a relatively high threshold. Seismic prediction has now used satellite remote sensing technology, GPS positioning technology. Other areas of study required a variety of instruments and laboratory equipment. And civil science enthusiasts is very difficult to get to these machines and equipment. A lot of civil science enthusiasts are very persistent: Wuhan Li Yuming Farmer at bankrupt, self-made submarines; Sichuan Farmer Cao book homemade plane; Anhui peasant DU Tatsu flying saucer made fund-raising; Tianjin peasant debt should verify Goldbach Conjecture. These non-governmental science and enthusiasts share a common characteristic, that is, put all the scientific research as sustenance, non-utilitarian point heart, which the scientific spirit should be protected at the same time to maximize their talents. 

American Society for Biochemistry introduction Fang doctor, rarely seen everywhere in the United States to promote their own major scientific discovery 』『 civil scientists, but the United States has a lot of serious science enthusiasts. The scientific community also used a variety of ways to encourage the exchange of scientists and science enthusiasts, cooperation, as part of the work of popular science.

Scientists under the guidance of the United States science enthusiasts sometimes make scientific discoveries. For example: elementary math problems. Elementary math and some small issues to be identified and solved, and to solve these problems do not need to have too deep maths training, relying mainly on the reasoning abilities are tight, which was left a space science enthusiasts. In addition, the natural history are a range of professional and amateur between the disciplines, apart from professional training, more emphasis on patient and meticulous observation, under the guidance of experts, amateurs can also participate in the research. Such as the United States there is a set of ad hoc observation of birds, from amateur expert guidance on how to observe and record the activities of birds, collected the information available for further expert analysis, research. In addition, the discovery of asteroids, comets, discover new species, new fossils and so on all the samples because a lot of quantity, science enthusiasts can play their role. 

Jin-Zhong Sun also said that there is a lot of foreign fans will be civil scientific research organizations of their own bodies, or even web magazines and so on. They will hold regular exchanges of activities and some can also be involved in a number of international exchange activities. To address the problem of internal civil science enthusiasts with the Academy of Sciences of the problem of poor communication experts, first of all lovers of civil science and research fields should be set up according to their own societies and organizations, such as Astronomical Society, the study of math, earthquake prediction Society, the study of the theory of relativity. Then communicate through an internal study to jointly improve. Academician Yuan Longping have been made to develop "innovative promotion and protection of civil law." Government to set up civil science enthusiasts and experts in communication channels and exchange platform for civil science enthusiasts have the opportunity to communicate equally with experts, develop a scientific way of thinking, it also brings many experts point of information. At the same time, civil science enthusiasts to small inventors, small innovative start, select some of the knowledge do not ask for much, do not have a strong program of subjects. 

JING Hai-rong think, it is necessary to set up non-governmental scientific experts and enthusiasts communicate platform, must be over z tumultuous T conditions: first of all government departments from the capital, on support staff; followed by non-governmental science enthusiasts also enhance their own knowledge of the basic study to master the scientific way of thinking, to increase scientific and technological workers and occupational common language; Finally, scientists have to itself and decide on many enthusiasts to listen to the voices of civil science, and actively take part in science enthusiasts and civil communication.
