Posted by: admin , February 23, 2017

This morning, NASA announced that it has found 7 earth-sized planets orbiting a star 40 light years away, with life or water possible on all of these planets.
Of these planets, NASA believes 3 are in the’habitable zone’, being the area around the star where life is most possible.
The discovery was made using the Spitzer Space Telescope and is said to be the greatest number of ‘exoplanets’ found around a single star.
The star is called TRAPPIST-1, and it is significantly smaller than Earth’s sun.
The Hubble Telescope has started looking at 4 of these planets (including those in the habitable zone).
According to the head of NASA Science Directorate, this proves that “finding the next Earth is not a question of if, but when”.
