NASA scientists have discovered a rare visitor from beyond our solar system, a new interstellar comet speeding by on a brief ...

Sometimes "the universe comes to us," writes the European Space Agency. For the third time since 2017, an interstellar object ...

On July 1, 2025, a telescope in Chile detected something unexpected: a faint object streaking across the sky at an unusual ...

Astronomers have confirmed the third interstellar object on record is dashing through our solar system. Dubbed 3I/ATLAS, it ...

I/ATLAS, also known as C/2025 N1 (ATLAS), originated in a distant star system, far beyond the boundaries of our solar system.

Hopkins and Lintott are two of the six authors of a new paper that uses the new model to trace the origin of Comet 3I/ATLAS, and it appears to be coming from a completely different region of the ...

You can watch comet 3I/ATLAS live online tonight (July 3), thanks to the Virtual Telescope Project, which will livestream views beginning at 6:00 p.m. EDT (2200 GMT).

But now 3I/ATLAS appears to be a comet like Borisov, the second interstellar object observed. For a comet, the brightness comes from sunlight bouncing off a plume of gas and dust known as a coma ...

Astronomers have confirmed the presence of 3I/ATLAS, a rare interstellar comet originating from a distant star system, now traversing our solar system.

“ [Comet 3I/ATLAS] will be a tiebreaker of sorts,” says Mario Jurić, an astronomer at the University of Washington and discovery software lead at the recently completed Vera C. Rubin ...

Astronomers do know that 3I/ATLAS is a comet that's about 670 million kilometers (416 million miles) away from the sun. Based on current projections, it poses no danger to planet Earth.

Anatomy of an interstellar object Comet 3I/ATLAS follows two other intriguing interstellar objects, called ISOs, that once passed through our solar system: ‘Oumuamua in 2017 and 2I/Borisov in 2019.
