Comets

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.

'Dark comets,' which have no visible tail, could also explain the strange behavior of the interstellar object 'Oumuamua.

By the end of this summer, we may have a good idea as to whether we'll have a bright naked-eye comet gracing our early autumn evening sky, known as C/2023 A3 (Tsuchinshan–ATLAS).

Perhaps one comet per year will approach the edge of naked-eye visibility.

Comet 12P/Pons-Brooks visits the inner solar system every 71 years and will reach its closest to the sun on Sunday (April 21), appearing bright enough to possibly be seen by the naked eye.
