Dark comets are small bodies with no detected coma that have significant accelerations explainable by outgassing of volatiles, analogous to the first interstellar...
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have...
456P/PANSTARRS, an active, main-belt asteroid first spotted in 2021, is recurrently active, and activity is likely driven by the sublimation of volatile...

In a paper published in the Proceedings of the Royal Society A: Mathematical Physical and Engineering Sciences, researchers at the University of Cambridge...
Around 12,800 years ago, Earth collided with fragments of a disintegrating comet, triggering Younger Dryas climate change; this event created environmental...
The new observations from the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope show that the main-belt comet 238P/Read...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
Astronomers with the SKYSURF project have searched through 200,000 archival images from the NASA/ESA Hubble Space Telescope and made tens of thousands...
About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. This impact coincides...
About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated...
New research led by Curtin University geologists suggests that regions of space with dense interstellar clouds may send more high-energy comets crashing...
