Many habitable planets could exist in galaxy

Kitt Peak National Observatory (KPNO) astronomers Helmut A. Abt and Saul G. Levy recently reported that the number of stars in the Milky Way galaxy that can have habitable planets circling them is much greater than previously believed. This could mean that life similar to that on earth might be much more probable among nearby stars.

‘The evidence we have that hot stars, as well as cooler stars like our sun, have companions orbiting them could mean that the number of stars which can have habitable planets is greatly increased,’ Abt said. It had been thought previously that since hot stars spin fast, they are unlikely to have companions.
