Metallic Scar: Astronomers Spot Cannibal Star with Unique Mark

Astronomers using the Very Large Telescope have observed a scar on the surface of a white dwarf, indicating ingestion of planetary debris, shedding light on the behavior of "cannibal" stars. The scar, made up of metal elements from a planetary fragment or asteroid, was found to be prevented from mixing with the rest of the star's surface by its magnetic field. This discovery provides insight into the fate of our own solar system, as our sun is expected to become a white dwarf in about 5 billion years.
