Astronomers have announced that they have discovered eight more that likely exist in temperature ranges where life could exist.

The astronomers began their path by examining candidates for planets that had been identified by NASA’s Kepler . The candidates were analyzed using a supercomputer algorithms at NASA’s Ames facility.

After exploring the statistical likelihood of the planets’ existence, the followed up with months of observations using a variety of different methods. The planets are distant enough, however, that their habitabiliy is still only a likelihood, not a .

“We don’t know for sure whether any of the planets in our sample are truly habitable,” David Kipping said in a statement. “All we can say is that they’re promising candidates.”

The two most potentially Earth-like planets of the group of eight are Kepler-438b and Kepler-442b, both of which circle red dwarf are are respectively 70% and 97% likely to be in the habitable temperature zones of their respective . However, it should be that there are serious issues regarding the habitability of planets circling red dwarf , so confirmation will significantly more study.
