Life In The Habitable Zone
Scientists at the University of Aberdeen say that earth-sized planets are able to support life at least ten times farther away from stars than we thought before. Maybe not life as we generally think about, but it extends the “habitable zone” that includes life deep below ground. The team of scientists says that although water may be frozen on the surface of a planet, temperatures below the surface may be warm enough to contain liquid water and support life. Their new computer model found that rocky planets a few times larger than Earth could support water about 5 km below the surface even in interstellar space and even without an atmosphere because larger planets generate more heat!
