Oldest meteorite collection on Earth found in one of the driest places

Meteor illustration (stock image). Credit: © Vadimsadovski / Adobe Stock Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a…

A family of comets reopens the debate about the origin of Earth’s water

Illustration of comet over Earth (stock image). Credit: © Paul Fleet / Adobe Stock Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, bringing together CNRS researchers at…
