We Found a Planetary Graveyard | SciShow News

The video discusses how light from distant objects reveals their past states and introduces a new method to study ancient planets by examining white dwarfs. Researchers found lithium in white dwarfs, indicating vaporized crusts from destroyed planets. The video also covers the discovery of 'Far, Far Out,' the farthest known object in the solar system, and its unique orbit influenced by Neptune. These findings provide insights into the composition of ancient planets and the history of our solar system.
