Comets

A new paper suggests that comet C/2023 A3, also known as Tsuchinshan-ATLAS, may completely break apart before it reaches its closest approach to Earth in October. If the comet does survive long enough to reach us, it should be bright enough to spot with the naked eye.

A strange class of space rock known as a "dark comet" has qualities of both asteroids and comets — and the hard-to-spot objects may pose a larger threat to Earth than we thought, according to new research.

Comet 12P/Pons-Brooks, also known as the devil comet, recently made its closest approach to Earth for more than 70 years. During this close encounter, astrophotographers spotted a seemingly impossible "anti-tail" coming off the comet thanks to an extremely rare optical illusion.

The incoming comet Tsuchinshan–ATLAS might become as brilliant as Venus during its close approach to Earth this fall, potentially making it visible to the naked eye.

A surprise coronal mass ejection recently smashed into Comet 12P/Pons-Brooks, briefly causing the "devil comet" to lose its tail — and a NASA spacecraft caught the whole thing on camera.

The explosive green 'devil comet' 12P/ Pons-Brooks is about to reach its closest point to the sun. Here's how to see the rare visitor at its best and brightest.

The green comet 12P/Pons-Brooks is now visible in the night sky in North America. Here's how to see it.

New, specially edited photos show a previously unseen swirl of light surrounding the city-size comet 12P/Pons-Brooks, which is currently racing toward the sun and will later zoom past Earth.

Comet 12P/Pons-Brooks is currently sailing past the Andromeda Galaxy in the night sky as it races toward Earth, and you can watch it live this week.

The green-tinged cryovolcanic Comet 12P/Pons-Brooks, which is due to pass by Earth later this year, was recently spotted zooming past the crimson-colored Crescent Nebula in stunning new photos.
