When asteroids travel too close to white dwarfs, the dense remnants of stars that have exhausted their nuclear fuel, powerful gravitational forces can tear them apart. However, new research from Planetary Science Institute (PSI) suggests that these asteroids don't immediately break into dust. Instead, most of the mass initially remains in larger fragments, revealing a previously overlooked step in how debris forms around dying stars.
