An interstellar trespasser known as 3I/ATLAS is almost certainly a comet. So, why do so many people think it's ...

Avi Loeb says 3I/Atlas is gaining speed as new images show unusual tail changes. We unpack the data, comet physics, and whether it poses any risk.

Comet 3I/Atlas is soon going to be closest to the Sun in its journey through our solar system. Here are five facts that shed light on this phenomenon.

Comet 3I/ATLAS did not explode as some reports claimed. Instead, it naturally fragmented—a common process for comets nearing the Sun. Scientists confirmed no alien or explosive activity occurred.

They have detected the first-ever radio waves allegedly coming from the interstellar comet 3I/ATLAS. While the signal ...

I/ATLAS sent a message to Earth after it passed its perihelion. Scientists found the interstellar object brightened fivefold ...

NASA issues a new update on 3I/ATLAS, confirming it is 'unambiguously a comet' and poses 'no impact risk', as new data on its ...

You may have seen claims about three comets discovered this year: C/2025 K1 (ATLAS), C/2025 R2 (SWAN), and C/2025 A6 (Lemmon), being visible in the fall skies. Yeah ... about that. Other WRAL Top ...

Dr Loeb has put the odds of an artificial origin for the 3.5-mile-wide 3I/ATLAS at 40%, questioning how it already had a tail ...

NEW ORLEANS (WVUE) - Two comets are visible in October. All you need is a drive away from light pollution and binoculars or a telescope. The comets that will be visible are the C/2025 R2 (SWAN), and C ...

Two bright green comets are streaming through the skies and are visible to skygazers in the Northern Hemisphere. Both hail from the outer edges of our solar system—possibly what's known as the Oort ...

The comets A6 (Lemmon) and R2 (SWAN) are visitors from the chilly fringes of our solar system, and could even be visible at the same time. By Marina Koren If you like comets, this month is shaping up ...
