About this listen

The comet 3I/ATLAS is taking a long holiday journey this year. It’s visiting from another solar system altogether. Those interstellar origins have the Internet rumor mill questioning whether 3I/ATLAS came from aliens. Co-hosts Emily Kwong and Regina G. Barber dive into that, plus what it and other interstellar comets can tell us about planets beyond our solar system.

Read more of NPR’s coverage of 3I/ATLAS. Also, if you liked this episode, check out our episodes on:
