New research on Comet 67P indicates that its water may be similar to Earth's, contradicting earlier findings by Rosetta's ...

A reanalysis of the data from the "rubber-ducky" comet 67P, collected nearly a decade ago, suggests comets may have deposited a lot more water on Earth than scientists previously thought.

The rocky bodies, which look like asteroids but act like comets, could comprise up to 60% of near-Earth objects.

Scientists have revived the theory that short-period comets could have played a crucial role in filling Earth's oceans with ...

Comet 67P's water has the same molecular signature as Earth's oceans, suggesting it may have contributed to Earth's water ...

Water is fundamental to life on Earth, yet the origins of this vital resource remain a scientific puzzle. Researchers have ...

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 ...

Scientists uncovered new insights regarding the potential role of comets, particularly Comet 67P/Churyumov-Gerasimenko, in ...

The origin of Earth’s abundant liquid water is still debated. Research suggests some water came from volcanic vapor that ...
