"In a new paper published in Nature today, a team of scientists (led by Martin Cordiner from the NASA Goddard Space Flight Center) have shed fresh light on the comet’s origin. Their results reveal it to be a true galactic fossil, far older than the Solar System."

How fascinating that comet 3I/ATLAS is older than the Solar System. It’s the oldest object of interstellar origin we’ve ever seen here in our solar system! 😎 #3IATLAS

A process called hot bottom burning helped scientists determine that interstellar comet 3I/ATLAS is about 12 billion years old — nearly 3x older than the solar system. #interstellarcomet #3iatlas #cosmicage
