"Kepler" will be launched within three years or will find extraterrestrial "earth"

The United States National Aeronautics and Space Administration (NA "Scientific American"), the Kepler satellite, Beijing is expected to be March 7 at 11:48 noon launched, will the search for extraterrestrial life to turn a new leaf. This to sixteenth and seventeenth-century German astronomer Johannes Kepler (Johannes Kepler) named the exploration program, will be used for more than three years time to study a group of stars, looking for the brightness of stars on weak cyclical darken - This is around there is a planet around the star signs. Although astronomers have been using this technology (together with other technologies) in the discovery of extrasolar planets more than 300 stars, but the quality is greater, the distance of stars very near the "hot Jupiter", they show a very high temperature, the fundamental not suitable for survival of life. Kepler is the advantage of satellite is that it is carried by very sensitive equipment, able to detect smaller, colder, more suitable for life to survive, more similar to the Earth of alien planets. 

     Carnegie Institute of Washington at the United States engaged in the star and planet formation research planetary scientists, Kepler Science Team member (Alan Boss) at a new book, said the mission will look for outside solar system to open a gate to life. He said that if lucky, Kepler satellite should be able to prove that only exist in the Milky Way on a number of one billion planetary habitat for life, and in the whole universe, and similar to the Milky Way galaxy has at least ten (10 of the 21 th power), many that can not be exhaustive. We take on this new book of this topic, the Boss had an exclusive interview. 

     The following is a record after finishing the interview: 

     "Scientific American": Your new book called "crowded universe," (The Crowded Universe). What is the meaning of the title? 

     The main thrust of this book is to prove why someone would say that the universe may be the existence of life everywhere. Me in this book put forward the view that we already know of the Earth may be an incredible Ordinary - each a star similar to the sun perhaps have a few planets like the Earth, or similar. At least in my opinion, if there is so many lives for the survival of the planet 50 billion to exist on, most of the planet began to develop something on Change is inevitable. 

     If the planet has emerged on the water, some comets carry amino acids and other interesting life can evolve constantly falling into the hands of one of chemical substances, how to prevent these things can develop into some form of death? 

     Life is a very stubborn things, willing to be able to stay at any of the places to take root, I think as long as one has the opportunity to be the origin of life in any place. Spielberg may not necessarily have the kind of movie where the dwarves, but there must be some similar archaea or bacterial organisms. They will produce and release oxygen and gases like methane, which are in the atmosphere we can see. We may be unable to determine whether there is a planet on the lives of intelligence or dinosaurs, but at least we can determine whether there exist mucus bacteria. Therefore, we intend to go looking for mucoid strains.
