Astronomers have uncovered the chemical fingerprints of destroyed exoplanets by analyzing debris absorbed by white dwarf stars. The remnants reveal that many alien worlds have compositions remarkably similar to the rocky planets in our own solar system, while others appear to be rich in water. The findings offer a powerful new way to study the formation and diversity of planets across the galaxy. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
