Interstellar comet 3I/ATLAS likely formed where its star's light couldn't touch it

- Scientists determined that the interstellar comet 3I/ATLAS likely formed in a region of its original solar system where its home star's light could not reach.
- Researchers used the object's composition to conclude it originated far from its parent star.
- Studying these interstellar visitors provides data on how planets and smaller bodies form around stars in other parts of the galaxy.
