    Wednesday, Feb. 22 and on air live on NASA Television and the agency's website,The national space agency was hold a news conference and present anew discovery it made “beyond our solar system.”


    NASA Astronomers announced that four new Earth-sized exoplanets have been discovered a dwarf star about 40 light-years away from the Earth, and that three may contain liquid water and be able to sustain life.


    NASA wrote on its website " NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.


    Brice-Olivier Demory,the professor at the University of Bern's Centre for Space and Habitability said :" Looking for life elsewhere, this system is probably our best bet as of today," a small, ultracool star.

    The discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1.


    TRAPPIST-1, a red dwarf star that's a short 39 light-years distant, is hitting the headlines again,it is similar to the inner solar system around Earth's sun, Demory's analysis of data from NASA's Spitzer Space Telescope showed.


    TRAPPIST-1 was in the news last year because of the discovery of three accompanying planets. Now a team of astronomers has found four additional worlds in orbit around this ruddy sun.


    Nasa announced the discoveries of 1,284 new planets, nine of which were in the "habitable zone".
    Nasa Headlined the event address a “discovery beyond our solar system.” and it allow Media and the public to ask questions using the hashtag #AskNasa during the conference.
