Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

Newfound interstellar object 3I/ATLAS may be carrying pristine material from early in the Milky Way’s star-forming history.

Over the next few days, astronomers will pull together evidence to determine whether the object is a comet.

An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed.

Until now, astronomers had only spotted two confirmed interstellar objects. The first was ‘Oumuamua, a small, cigar-shaped object that visited our solar system in 2017.
