Passages of the Solar System have only been established in three interstellar objects, but the construction of new telescopes ...

The international team of astronomers reports that all of the types of ice in the comet appear to be sublimating. This is the phase change where a solid turns into a gas, skipping the liquid phase.

Telescopes have captured the dramatic process of a comet crumbling into multiple pieces as it journeyed through our Solar System. Freshly released images from the Gemini North telescope in Hawaii show ...

Comet 3I/ATLAS, only the third interstellar object ever observed, is making its final pass through our skies, offering a rare last glimpse before vanishing into deep space forever.

Comet C/2025 K1 ATLAS, a relatively new visitor from the outer solar system, has broken apart after swooping close to the Sun ...

Avi Loeb famously dubbed the October 27 perihelion event of 3I/ATLAS as a possible black swan event that would render all our material possessions and money useless if the object turned out to be a ...

This week in science: the choice between tea or coffee could have greater consequences than you think; interstellar comet 3I/ATLAS makes its closest pass to Earth; astronomers track a runaway ...

All eyes have been on the nearly 5-6 km long exocomet, including NASA’s Transiting Exoplanet Survey Satellite, aka TESS.

3I/ATLAS has passed its closest point to Earth, meaning we will soon lose sight of it for good. Some scientists want to send a spacecraft to chase down the alien comet — or the next interstellar ...

Avi Loeb warns 3I/ATLAS's symmetrical jets defy comet norms, hinting at possible tech. Hubble data and expert debate fuel the mystery.

A team of astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spaceship. The comet ...
