Astronomers manning an asteroid warning system caught a glimpse of a large, bright object zipping through the solar system late on July 1, 2025.

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

Late in the evening on July 1, a telescope in Chile that is part of the global, NASA-funded Asteroid Terrestrial-Impact Last Alert System (ATLAS) picked up on a new moving dot in the sky, an object traveling past the orbit of Jupiter.
