The asteroid into the atmosphere

October 6 last year, astronomers found a 4 meters long and weighing about 83 tons of asteroid 2008 TC3, the calculation results show that, 2008TC3 chance of colliding with Earth as much as 100%. At this time, arrived at the asteroid from the Earth's atmosphere is only 19 hours before. However, in the asteroid entered the atmosphere after the combustion exhausted, residues falling in the Nubian Desert in northern Sudan, about 30 kilometers outside, the scattered wreckage of a number of asteroids and weighing about 3.95 kilograms. 

 This is the first time scientists are tracking the course of asteroids colliding with Earth. Scientists believe that in 1908 and swept the Tunguska forest in Siberia large asteroid celestial bodies in general, may be every 200 years the Earth will be hit first. Once the asteroid entered Earth's atmosphere, colliding with Earth after the explosion or disintegration occurs. Such as an asteroid exploded in a city or directly over the collision will lead to a devastating disaster. 

 Astronomers pointed out that although the number of science fiction movies of asteroids colliding with Earth would, in fact, the possibility of asteroids colliding with Earth exist. For the existence of threatening to destroy the asteroid is very necessary, but such a threatening asteroid, or even more complex than the movie. 

 Best to avoid such a disaster is to change the asteroid crashed into Earth orbit. 

 Space Shuttle Discovery's safe return to Earth 

 ● The United States space shuttle Discovery, landed safely on the 28th the Kennedy Space Center in Florida, the successful completion of the delivery to the International Space Station components and solar panels bracket task. 

 Discovery Time in the Central Plains at 3:14 on the 29th to land because of bad weather than the scheduled time for more than an hour late. 

 Discovery's trip is the first space shuttle flight this year. Time of the next space shuttle flight is tentatively scheduled to present on May 12. 

 Obama video greetings from the International Space Station astronauts connection 

 ● Barack Obama President of the United States, on the 24th and the International Space Station astronauts on the 10 video connections, greeting each other with questions. In the call, the International Space Station Commander Mike? Fink told Obama, a space station orbit the earth every 90 minutes around every 24 hours to see the sunrise 16. 

 Sandra female astronauts? Magnus, in November last year, started work at the space station, Barack Obama in the video signal, to see her because of weight loss and long hair in the air being released into the atmosphere. Obama asked: "long hair in the space station trouble? Want to cut point? Popular short hair." Magnus replied: "honestly, I cut hair look good, so long insisted on staying . " 

 This is the first time since Barack Obama became president talk with astronauts. Obama connection with the day with the astronauts, as well as primary and secondary school students from Washington, their own question: "What astronauts eat?" "Can play in space electric?" "There are few stars in space?" "What in order to become an astronaut? "... ... the International Space Station astronauts original Permanent 3. 

 On the 15th of this month, seven space shuttle Discovery astronauts traveling from the United States John F. Kennedy Space Center, Florida, launched into the international space station on the 17th. Discovery is scheduled to leave on the 25th International Space Station, on the 27th to return to the Kennedy Space Center. 

 Microsoft plans to cooperate with NASA to create a virtual telescope

Coming through the system, the public will be able to access from worldwidetelescope.org Mars, the Moon and Other Celestial Bodies, the universe of high-definition images and scientific information. 

 NASA officials said, which is in line with the new NASA Administrative open and transparent policy. NASA provided to the Microsoft for more than 100 TB of data, including the August 2005 launch of the Mars Exploration Orbiter (MRO), lunar exploration Orbiter (LRO), such as photographs. It will help stimulate the general enthusiasm for astronomical exploration.

Hubble Space Telescope archive images found abandoned by the new exoplanet

Photographs from 1998 found in extrasolar planets 

 NEW YORK News April 3, according to foreign media reports, astronomers have recently re-examine the  Hubble telescope the past 15 years shooting a large number of images and data files, and from the discovery of a previously overlooked new extrasolar planets. 

 HR8799 To further explore the surrounding stars in a star running more planets, astronomers have carefully studied the  Hubble telescope in 15 years a large number of images collected by data files. Astronomers using a shading method, the stars have been observed to mask the bright light, so that may be found running around some of the star exoplanet light of the weak. It is through this method, astronomers finally taken in 1998 found an image of this extrasolar planets. This technology can be applied from Hubble telescope is similar to the more than 200 data sets can also be used by ground-based telescopes to obtain a large number of image data. 

 University of Toronto astronomer David -is one discoverer. David said that Now we have proved the feasibility of this approach. We can be applied to all observational studies and researches files, can be used to discover whether these images in a hidden planet. Hubble data files can best embody the scientific efficiency. It is easy to understand, and its structure is very suitable for information search scientists. According to the U.S. computer scientists Rensselaer Polytechnic Peter - Fox introduced so far  Hubble data files have been used for more than 6 times. In fact, experimental or other scientific tools have had a mass of information, but most are hard-copy format or hard to read vs Reserve, but not after the general analysis. 

 Hubble data file for David's research work provides the meta-data and query functions. David explained that You can use different parameters, different goals and different wavelengths name query, query is easy. But more importantly, the data quality is very high, they are processed and calibrated, it is also a high-quality search results. Proven this technology in the next may be more widely used. David said launched in the near future," James - Webb "telescope, will certainly use this technology as the search for extrasolar planets, one of the strategy. We need a way to diminish the stars shine. James  - Webb telescope will be launched in 2013, and dedicated to the search for extrasolar planets Kepler Space Telescope was previously launched in early March. 

 David further explained that the Department of extrasolar planets is a difficult observation of celestial bodies, which is located in our solar system around a star outside the run. Although, according to astronomers speculated that in reality there are many extrasolar planets to be discovered, but so far, astronomers identified only 300 extrasolar planets, which some of the planet's environment, with the formation of life on Earth's environment very similar. So far, astronomers are red through the space telescope to collect data to understand the atmosphere of extrasolar planets. However, as soon  Spitzer infrared telescope will all run out of the refrigerant, which would severely limit the capacity of its observation. Astronomers said that from the Earth to an extrasolar planets to see the atmosphere, it is necessary for a large number of calories eruption, and the atmosphere necessary for the existence of no wind or very little wind. In addition, when this Department of extrasolar planets from the star behind it through, the cover star, the planet is a clear need to just quiet night, so that astronomers can accurately measure the thermal emission of its minor changes. 

 As of January 2009, scientists around the world in a total of 285 planetary systems discovered 335 extrasolar planets. In the near future, they seem to discover another planet  Previously found to have the atmosphere of extrasolar planets are orbiting telescope  Spitzer found. Need to add that, in the current discovery of extrasolar planets, most of them are Jupiter-like gaseous giant planets like. These planets are usually very close distance from the star, so the surface temperature is usually over in a few hundred degrees Celsius.

Fear of an earthquake disaster area with the recurrence of strong earthquakes

The scientific community that a strong earthquake on the 6th morning, resulting in many dead or missing in the central region of Italy, as located at the plate and the other two micro-plate to take care of the Convergence area prone to earthquakes of this on, but do not rule out the next few months of strong earthquakes will happen again. 

 Italian Institute of Geophysics, said that early morning in the Apennine mountains (Apennines) earthquake in central, as far as measuring the size of six. Second, place in Rome, about 100 kilometers northeast of the Agency. Bear the brunt of the historical city of Aquila. 

 Edinburgh, Scotland, "the British Geological Survey agency" experts said Mason, Apennine mountain was prone to strong earthquakes, earthquake occurred on the 6th degree of the earthquake that is not surprising. 

 Apennine ridge runs through the Italian peninsula, in the past century, the mountains and the surrounding area of five large earthquakes have occurred, claiming about 34,000 lives. The earthquake occurred on the 6th for the past twelve years to the third largest, has a radius of 140 kilometers range of feeling. 

 Paris, France, "Institute of Geophysics," said geologist , Italy The earthquake occurred very close to the surface in place, it can be said is that the underground city of Aquila. 

 Northern Ireland University of Ulster, Professor of Geophysics Mike Barry said that these form a "complex tectonic"; to Apennine mountain as an example, the problem in the normal fault, the crust was brittle underground sideslip actions, fault and therefore follow the torn oblique angle.

Global Ocean Observing local victims seek

Institute of Oceanology, State Oceanic Administration of the second satellite marine environment National Key Laboratory of Dynamics researcher Xu Jianping 

With economic development, scientific and technological progress, mankind should not only intensify the study of natural disasters, and try to predict the day, week, month, year or even the weather conditions, but also a prediction a few years, dozens of years disasters to happen so that mankind can advance on disaster prevention at the source. And to accurately forecast the weather still need to be large-scale and even global, regional and long-term accumulation of observational data, but also the need to enhance maritime disasters caused by weather or the awareness of anomaly. In fact, the development of marine science, especially in the business of ocean and climate forecasting technology, on the ocean wide (the size of the Earth accounts for 71%%) large-scale, quasi-synchronous and deep-seated lack of survey data has been restricted bottlenecks in their development. The advent of the 20th century 90's section of the Argo buoys, and in 2000 launched the international Argo program to bring ocean and atmospheric scientists a rare opportunity, so that depth of human understanding and knowledge of the sea real-time large-scale changes in weather conditions improve and marine forecasting accuracy, effectively prevent the worsening global weather and marine disasters, the desire will become a reality. The frequency of natural disasters the world is at the call of human need to strengthen the global ocean observing real-time. 

With the international Argo program on an international series of newly developed high-tech marine technology, such as Argo Profiling Float, satellite communications systems and data processing technology in the global ocean at the creation of a real-time, high-resolution and fully automated monitoring system so that Express, accurate, large-scale gathering of the global upper ocean temperature and salinity of the water profile information, help people deepen their understanding of ocean temperature and salinity vertical structure, circulation and energy, as well as understanding the process of water balance and to reveal the sea ─ ─ the mechanism of interaction, to further improve the model initial fields and improve the air-sea coupled model, thereby enhancing the long-term weather forecasting and the ability of short-term climate prediction, including with the ENSO-related events (such as floods, droughts, etc.) of the forecast capacity and the Pacific Decadal Oscillation and other re-recognize. 

North of the Pacific, this region not only has the world's oceans and borders in the West most ─ ─ Kuroshio flow, as well as the global ocean and climate system, the largest inter-annual changes ─ ─ El Nino phenomenon, but also across the Pacific and Indian Oceans have great Warm Pool, as well as precipitation with the world's largest ─ ─ Pacific ITCZ, which is an international marine scientific research has been the hot waters, there are many issues to be dealt with major scientific frontier, much-needed strength to carry out exploration and research organizations. However, the ocean environment observation data, especially long-term, large-scale and real-time ocean observing a serious lack of information, the impact of China's marine and atmospheric scientist at the forefront of research hot areas of the outcome of the driving force for innovation. 

To this end, in the next few years, our country should be increased in the North Pacific and East Indian Ocean buoy deployment efforts. This is not only because Argo observations on the current international Nets are the only real-time of a global ocean observing system, and its observation and the accumulation of information on the marine and atmospheric science and the development of major scientific significance; but also for our country suffering from such a marine and the impact of climate disasters, maritime power, especially during the last long-standing close to the ocean off the coast of our country and not enough emphasis on the Global Ocean Observing observed a serious shortage of information on the accumulation of the countries involved in Argo real-time global ocean observing network is more important practical significance.
