While NASA continues to search for life in the solar system, for example, on Mars and on Jupiter's ice moon and Saturn, the panel focused on the search for life beyond the solar system.
Charles Bolden, a former astronaut and NASA Administrator, who opened the discussion by saying "in a very broad universe infinite, impossible just his own man."
One of the major advances in the discovery of the world outside the solar system is the Kepler Space Telescope, which was launched in 2009. Important tool in expanding knowledge of exo planets or planets orbiting stars outside the solar system. This telescope has found most of the 5,000 potential exo planet, 1,700 of them have been confirmed. Kepler discovery has led scientists to conclude that there may be billions of planets in the galaxy.
A major step in finding extraterrestrial life is a potential satellite launch which conducted a survey of exo planets that transit in 2017, the James Webb Space Telescope in 2018 and Wide Field Infrared Survey Telescope - Telescope Focused on Astrophysics at the beginning of the next decade.
These tools will allow scientists to determine if a planet has exo atmospheric water vapor or carbon dioxide and atmospheric chemicals More.. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
