Metallic beads in Arctic mud point to a comet impact that may have triggered the Ice Age 12,800 years ago, challenging ...

A massive comet trail may have caused climate upheaval on Earth more than 12,000 years ago, sparking the Younger Dryas.

Hubble telescope captures third interstellar visitor 3I/ATLAS showing active dust coma racing through solar system.

Discovered last month by a telescope in Chile, the comet known as 3I-Atlas is only the third known interstellar object to ...

Comet 3I/ATLAS has been observed by the Hubble Space Telescope, which delivered new insights into this third interstellar ...

"We should put all possibilities on the table that it's a rock, a comet, or something else until we get the evidence, the ...

NASA’s Hubble Space Telescope has snapped images of a recently discovered interstellar visitor hurtling through our solar ...

This new measurement suggests some comets — particularly those such as 12P/Pons-Brooks — could indeed have delivered water, and possibly other life-essential elements, to a young Earth.

These strange objects could explain how water arrived on Earth, but may also be a previously unrecognised threat to our ...

The comet's approach toward Earth coincides with a total solar eclipse on April 8. Around that time, 12P/Pons-Brooks will be at or near perihelion, the point during orbit when it's closest to the sun.

NASA says comets like it could have delivered carbon to planets during the early formation of our solar system, when the Earth may have struggled to capture enough of the life-giving element on ...

The bright K2 comet — previously the farthest active comet ever spotted — approaches the Earth on July 13 and 14. Here's what it is and how to see it.
