Moon Record Analysis Challenges Impact Origin Of Earth’s Water

A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study argues that the […]

Hydrothermal System Helped Life Recover After Dino-Killing Asteroid

About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But according to new research, the crater […]
