Interstellar Comet 3I/ATLAS May Be Oldest Object Ever Seen in Solar System

Researchers estimate that the interstellar comet 3I/ATLAS might be up to 12 billion years old based on the composition of gases it spews. This age is approximately three times the age of our solar system, suggesting the object formed in a previous generation of stars. The discovery provides a rare opportunity to study pristine material from the early universe as it passes through our neighborhood.
