Explainer: Why sea levels aren’t rising at the same rate globally
The ocean is rising all over the world. The rise seems speedier in some places. What gives? Many factors, it turns out, affect where — and why — the tide gets high.

Asteroids may have delivered water to early Earth
Scientists shot mineral pellets at a simulated planet. It showed an impact wouldn’t have boiled off all of an asteroid’s water.

How Earth got its moon
How did our moon form? Scientists are still debating the answer. It may be the result of some one big impact with Earth — or perhaps many small ones.

Arctic Sea could be ice-free by 2050
Everyone contributes to the melting of Arctic sea ice, and all are in danger of making summer ice disappear there completely by 2050, a new study finds.
