Well, new discoveries of a habitable planet have been discussed in the journal Astronomy & Astrophysics. By using the radial velocity method scientists were able to make about 6,000 observations that enabled them to find new planets. These planets circle Tau Ceti, which is a star that is 12 light years away; this star is closely related to our Sun. The planets that surround Tau Ceti are possibly two to six times bigger than Earth. Interestingly enough only one of them is known to be five times Earth’s mass and is in Tau Ceti’s habital zone, this zone is the ‘Goldilocks zone’. Goldilocks zone is not too hot or too cold, allowing for potential life.
This new study is extremely important because it allows us to see how almost every star has planets. According to one of the authors of the study, Steve Vogt, “this discovery is in keeping with our emerging view that virtually every star has planets, and that the galaxy must have many such potentially habitable Earth-sized planets.” So if the world was to really end, there is still hope that we can go live light years away and still be able to survive.
