A newly discovered interstellar object named 3I/ATLAS may be the oldest comet ever observed at over 7 billion years old.
3I/ATLAS is the third known interstellar object to pass through our solar system and the first from a different part of the Milky Way galaxy.
Early observations show 3I/ATLAS is already active, emitting gas and dust like comets near the sun, indicating it could be older than our solar system.
Researchers believe 3I/ATLAS originated near an ancient star in the Milky Way's thick disk and may provide valuable insights into interstellar objects and their composition.
