NASA scientists have announced that the Kepler space telescope has spotted five planets about the size of Earth, orbiting stars in the Milky Way.
Man! That must have been hard on their teeth! Oh wait…the Milky Way Galaxy. Whew!
These planets are orbiting in what is known as the habitable zone, which puts them at a distance from their suns where liquid water could exist. Liquid water is a key ingredient for life to form.
“In a generation we have gone from extraterrestrial planets being a mainstay of science fiction, to the present, where Kepler has helped turn science fiction into today’s reality,” said NASA Administrator Charles Bolden.
The Kepler science team also announced the telescope found six planets, all larger than Earth, orbiting a single sun-like star.
