I/ATLAS was first spotted by NASA scientists in May this year. Ever since, it has displayed behaviors that are not just ...

The comet is on what’s known as a hyperbolic trajectory, which means that it doesn’t follow an orbital path around the sun.

The rare interstellar comet 3I/ATLAS is under intense scrutiny as it passes through the solar system. Spacecraft like Hera, ...

Observing 3I/ATLAS in this active phase will give some of the clearest insights yet into the mystery of interstellar comets.

An interstellar comet is drifting through the solar system, and it may be billions of years older than the sun. - ESA / NASA / ESO / M. Kornmesser illustration A giant comet spotted days ago hurtling ...

"It's like an aeon-old fridge, which will open during the next months to release some of its contents." New research investigates the possibility that different spacecraft could visit Comet 3I/ATLAS, ...
