Life Under a Tiny, Red, Angry Sun
So a recent study found that 6% of red dwarf stars may have Earth-like planets in orbit around them, and 75% of all stars are red dwarfs – which means that in a galaxy like the Milky Way with 300 billion stars, there should be 13.5 billion Earth-sized planets out there in orbit around red dwarfs. Could any of them be homes to extraterrestrial life…?
