NASA announced that earth size planets are discovered around habitable zone of a dwarf star called TRAPPIST-1. This newly discovered solar system have seven rocky planets and all of them possibly have water on their surface .
This exo-solar system is discovered by NASA’s Spitzer Space Telescope and conformed that the newly discovered habital zone planets on TRAPPIST-1 solar system is 39.5 light year far from us and have 7 planets .Out of seven planets five planets b,c,e,f,g are similar in size to earth and rest of those planets are size between mars and earth . All of these seven planets possible have water and life on them. And these life may have initial phase of their evolution . Which are not advance scientific as human being on earth .If we can develope advance technology we could probably communicate to them in future . But everything on that planet is seems different and could not be predict because they are billions of miles from us . We need 40 year to reach them even if we traveled at the rate of speed of light .
The planets also are very close to each other. If a person were standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.
