A White Dwarf Star Consumes Its Planetary System | NASA Goddard

A White Dwarf Star Consumes Its Planetary System | NASA Goddard

A star’s death throes have so violently disrupted its planetary system that the white dwarf star left behind, is siphoning off debris from both the system’s inner and outer reaches. This is the first time astronomers have observed a white dwarf star consuming both rocky-metallic and icy material, the ingredients of planets.

Archival data from NASA’s Hubble Space Telescope and other NASA observatories were essential in diagnosing this case of cosmic "cannibalism." The findings help describe the violent nature of evolved planetary systems and can tell astronomers about the makeup of newly forming systems.
