Water likely to be common on other planets

Water-rich asteroids are thought to have brought water to countless other worlds throughout the universe.

Most of the water on the Earth is believed to have been delivered here by asteroids during the earliest days of the solar system, a process that could have easily been repeated on other worlds.

Evidence of this was found in a recent study in which scientists discovered heavy elements such as oxygen, magnesium, silicon and iron in the atmosphere of a distant white dwarf star, a clear indication of a collision with a water-rich asteroid.

"Our research has found that, rather than being unique, water-rich asteroids similar to those found in our Solar System appear to be frequent," said lead researcher Dr. Roberto Raddi. "Accordingly, many planets may have contained a volume of water, comparable to that contained in the Earth."

Finding one of these water-rich, Earth-like worlds however is likely to prove extremely challenging.
