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

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 ...

This interstellar object, known as 3I/ATLAS, is still pretty far from the sun, currently located between the orbits of the asteroid belt and Jupiter but heading toward the inner solar system.

That would soon change. To his surprise, the object—provisionally named A11pI3Z—turned out to be the third interstellar visitor known to science.

An interstellar object called 3I/ATLAS is passing through our solar system this year, NASA announced yesterday. Today at 6 p.m. ET, you can see it for yourself, thanks to a livestream from the ...

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 ...

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

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

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.

Astronomers spot a mysterious object from interstellar space. The object, 3I/Atlas, is traveling at 60 km/s. It poses no threat to Earth. NASA confirms it is the third interstellar visitor.

The object, dubbed "A11pl3Z" or "3I/ATLAS," spans approximately 25 miles, Josep Trigo-Rodriguez, as astrophysicist at the Institute of Space Sciences near Barcelona, Spain, told The Associated Press.

It has since been designated 3I/ATLAS by the Minor Planet Center (MPC), with "3I" marking it as the third known interstellar object. "There are tentative reports of cometary activity," The MPC ...
