Comets

While some are hoping for a bright "Halloween comet," astronomers say the speeding cosmic snowball has likely already broken apart.

Comet A3 Tsuchinshan-ATLAS proved to be photogenic as it lit up the early autumn skies of the Northern Hemisphere this month.

The cloud is basically a gigantic reservoir that may hold billions of icy celestial bodies. Two of those bodies will pass by Earth in the days leading up to Halloween.

Have you seen comet Tsuchinshan-ATLAS yet? If you haven't yet seen the bright, icy space rock that's traveled from the edge of the solar system, it's not too late. But you need to see it soon.

There's been talk of another spectacular comet putting on a show in our sky after Tsuchinshan-ATLAS. Unfortunately, however, it doesn't look like the newcomer will deliver.

Newfound comet C/2024 S1 will light up Earth's skies in late October before a super close slingshot around the sun.

The SOHO spacecraft captured amazing imagery of Comet C/2023 A3 (Tsuchinshan-ATLAS) zooming near the sun as the star unleashed a powerful X flare.

Comet C/2023 A3 Tsuchinshan-ATLAS will reach perihelion — and if it survives its close call with the sun, we may be in for a real treat.

A video filmed by NASA astronaut Matthew Dominick shows a rare glimpse of Comet Tsuchinshan-ATLAS as seen from the International Space Station.

We provide the latest details on this comet, which might (or might not!) blossom into a bright naked-eye object in our October evening skies.
