Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering objects exist beyond our Solar System. The find suggests fragments like comets and dwarf planets may be common ingredients of planetary systems.
