Oxygen And Water Evidence From Extrasolar Asteroid?

October 11, 2013

Researchers have, for the first time, discovered key components for life existing outside of our solar system-water and a rocky surface. Using the Hubble Telescope and the Keck telescope in Hawaii, the team from the Universities of Cambridge, Warwick and Kiel, detected an excess of oxygen in the debris surrounding white dwarf star GD61. They said the debris was from a shattered asteroid that contained considerable amounts of water. But they believe the asteroid had been part of a bigger body, like an exoplanet, that had been composed of 26% water by mass, far more than that of Earth. They say finding water in a large asteroid means the habitable planet building blocks once existed in that system and maybe, just maybe, still exist.
