Comets

The exact cause of 'Devil Comet' 12P/Pons-Brooks' flare-ups is unknown, though the best guess is that perhaps a fissure has developed on the comet's nucleus due to a build-up of gas.

An icy volcanic comet that is three times as large as Mount Everest, nicknamed the "Devil Comet," erupted again Nov. 14. This is the fourth explosive event for 12P/Pons-Brooks since July 2023.

Scientists suspect that comets may have delivered the key ingredients for life on Earth, and new research outlines how exoplanets could have received these deliveries, too.

The massive volcanic comet 12P/Pons-Brooks, which grows giant horns when it erupts, has exploded for a third time in five months as it continues to race toward the sun.

The comet C/2023 H2 (Lemmon) will reach peak brightness on Friday, Nov. 10, illuminating the sky and possibly becoming visible with the naked eye.

The cryovolcanic comet 12P/Pons–Brooks, which will make its closest approach to Earth next year, has re-sprouted its distinctive "horns" after its second major eruption in four months.

A fragmented comet that exploded in Earth's atmosphere initiated the first-ever farming village in Syria, according to new research.

After surviving its closest approach to the sun, Comet Nishimura was buffeted by a possible coronal mass ejection that briefly blew its tail away. The rare event was captured by a NASA spacecraft.

Comet Nishimura has surprised NASA by photobombing its STEREO spacecraft, revealing it seems to have held together after its brush with the sun on Sept. 17.
