NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object

Summary
Only Hubble with its unique ultraviolet vision could see this event
A celestial meal is taking place, and only the Hubble Space Telescope caught the feast in action. Just 260 light-years away — close in cosmic terms — a burned-out star called a white dwarf is snacking on a fragment of a Pluto-like object. The Pluto analog came from the system’s own version of the Kuiper Belt, an icy ring of debris that encircles our solar system. As the exo-Pluto wandered too close to the star, the white dwarf tore it apart and began snacking on it.
Thanks to its unique ultraviolet vision, only Hubble could identify this event. Scientists using Hubble analyzed the chemical composition of the doomed object as its pieces fell onto the white dwarf. They were surprised to find water and other icy content indicating that the object came from far out in the system’s Kuiper Belt analog. Without Hubble’s ultraviolet capability, this material — unseen in visible light — would not have been detected.
