cold fjord writes with this excerpt from the BBC: "Astronomers have detected the tell-tale signs of a shattered asteroid being eaten by a dead star, or white dwarf. The Hubble telescope spotted the event some 150 light-years from Earth. The researchers tell Science Magazine that the chemical signatures in the star's atmosphere indicate the asteroid must contain a lot of water. This makes it the first time both water and a rocky surface — key components for habitable planets — have been found together beyond our Solar System. ... Of the 1,000 planets so far identified beyond our Solar System, none has been definitively associated with the presence of water." More at Smithsonian Magazine.
