They found magnesium, iron, silicon and other heavy elements, which wouldn’t exist naturally on the surface of a white dwarf, suggesting that they fell onto the star from an orbiting object. The researchers also found a huge excess of oxygen—an amount, they say, that indicates the asteroid polluting the star’s surface was originally composed of 26 percent water. That’s pretty wet—Earth, by contrast, is only 0.02 percent water. “This work marks the first detection of water-rich rocks in exoasteroids, and is an important step in developing a comprehensive picture of exoplanetary systems,” says Kevin France of the University of Colorado at Boulder, who wasn’t involved in the research.
