Is the solar system an interstellar highway, with cosmic objects speeding past at warp speeds without human notice? That’s ...

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 ...

A rare but faint interstellar visitor from beyond our solar system is racing toward the sun — and you can watch it live online today! Astronomers have identified this cosmic interloper as 3I ...

Discovered in 2019, 2I/Borisov was clearly a comet, but one quite different from the ones we grow in our solar system. With very little water and a whole lot of carbon monoxide, a composition that is ...

Space Interstellar comet hurtling through solar system named 3I/ATLAS An object from another star has been seen entering the solar system at high speed, and is expected to whip around the sun in ...

A comet from a solar system outside our own was first noticed on July 1 by a NASA telescope located in Rio Hurtado, Chile, as part of the Asteroid Terrestrial-impact Last Alert System (ATLAS).

Astronomers have discovered a rare instance of a interstellar comet speeding through the solar system. The 3I/ATLAS was first spotted on July 1 by the NASA-funded Asteroid Terrestrial-impact Last ...

While every planet, moon, asteroid, comet and life form that formed in our solar system shares a common origin, a common heritage — interstellar visitors, it said, “are true outsiders. They are ...

The comet, recently designated 3I/ATLAS, was first observed on July 1 by the NASA-funded Asteroid Terrestrial-impact Last Alert System telescope in Rio Hurtado, Chile. At the time of its unexpected ...

3I/ATLAS, also known as C/2025 N1, is a comet from interstellar space, meaning it originated in another star system and entered our solar system on a one-time flyby. It was first spotted by the ATLAS ...
