Clouds come in all shapes and sizes
Here’s a basic breakdown of the different cloud types, as well as how clouds form and why they float.

Mars’ rust suggests it was once wet — and its seas frigid
Mars may once have held enough water to fill oceans and form coastlines. And the planet’s red dust hints that its seas would have been quite frigid.

Scientists Say: Frost Quake
When wet soil abruptly freezes, it creates high pressure underground. When the pressure releases, it can trigger a mini-earthquake called a frost quake.

Gravity ‘batteries’ might help a weighty renewable-energy problem
To store the energy generated by wind and solar power, researchers are looking at mammoth systems that raise and lower weights.
