The 3I/ATLAS comet was first spotted in July near Jupiter after it entered our solar system from another universe.
Here’s what’s known about it: the comet is continuing its journey through our solar system, making its way around the sun and back again.
The comet known as 3I/ATLAS was discovered this summer after it entered from another star system. It got its name because it is the third interstellar object known to have visited our solar system (3I), and because ATLAS was the telescope in Chile that discovered the object, according to Harvard astrophysicist Avi Loeb.
Avi Loeb has been closely tracking this object and exploring the possibility that it could even be alien technology.
The comet was discovered on July 1, 2025, out near Jupiter.
Scientists and physicists are saying about it, but no specific quotes are available.
