The map for seeking out life elsewhere in the cosmos may have just gotten a new must-have accessory. A new study from NASA suggests that having an asteroid belt like our own solar system's could be a key ingredient in the development of extraterrestrial life.
The Hubble Space Telescope may have just spotted the first collision between two asteroids ever detected by humans. Last week, scientists detected a mysterious X-shaped object in the asteroid belt between Mars and Jupiter.
