Michigan State University and NASA researchers discover seven dark comets that reveal new solar system secrets.

New research indicates that the water on Comet 67P/Churyumov–Gerasimenko has a molecular signature closely matching that of water found in Earth's oceans. This discovery revives the possibility that ...

which share a lot of characteristics with the comets from the so-called Jupiter-family – they follow highly eccentric orbits, and they are fairly large, measuring hundreds of meters across.

Water. All life on Earth requires it in some way or another, and it's hard to miss that roughly 70% of our planet's surface is covered in the stuff. Thus, understanding where Earth's water came ...

called outer dark comets, have similar characteristics to Jupiter-family comets: they have highly eccentric (or elliptical) orbits and are on the larger side, hundreds of meters or more across.

Either Jupiter's family will scatter it in-system again, where it will become a Jupiter-family comet with an orbital period of less than 20 years, or it will be thrown back into the Kuiper Belt ...

Outer dark comets, found beyond Jupiter, are large—spanning hundreds of meters. Their elliptical orbits resemble Jupiter-family comets, indicating ancient and possibly icy origins. Inner dark ...

The James Webb telescope has focused its attention on an oddball space rock lurking between Jupiter and Neptune. The unusual "centaur," named 2060 Chiron, has features of both comets and asteroids.

NASA shares images of comet C/2024 G3 (ATLAS) near the sun and stunning photos from Jupiter and Mars missions.

Tuesday, April 9: A 2%-lit crescent moon will be below Jupiter, with comet 12P/Pons-Brooks in between. Wednesday, April 10: A 7%-lit crescent moon will be above Jupiter and comet 12P/Pons-Brooks.
