"Cannibalistic White Dwarf Star Displays Metallic Scar from Devouring Planet"

Astronomers have observed a dead star, known as a white dwarf, with a metal scar on its surface, indicating that it consumed a fragment of a planet. This sheds light on the dynamic nature of planetary systems even in the end stages of a star’s life cycle. The observation, made using the European Southern Observatory’s Very Large Telescope, revealed that the star’s magnetic field played a key role in this process, resulting in the scar on the white dwarf’s surface. This finding provides insight into the potential fate of our own solar system as our sun is expected to become a white dwarf in about 5 billion years.
