Comets

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.

Halley's Comet was predicted to reach its farthest point from the sun on Dec. 9, beginning a 38-year journey toward Earth that culminates in 2061.

The latest and most violent eruption of the cryovolcanic comet 12P/Pons-Brooks, which will make its long-awaited closest approach to Earth next year, shows that the icy object may have lost its iconic devil horns for good.

Researchers have simulated how comets pinballing from one planet to another could deliver critical organic molecules to exoplanets.
