Waves in thin air with broad effects

Mars has a very thin atmosphere, with nearly one hundredth the density of ours on Earth, and gravity pulls with little more than one third of the strength we feel on our planet. As a result, dust storms can go global. For ...

InSight detects gravity waves, low rumbles and devilish dust

More than a year after NASA's Mars InSight lander touched down in a pebble-filled crater on the Martian equator, the rusty red planet is now serving up its meteorological secrets: Gravity waves, surface swirling "dust devils," ...

High-gravity water waves

What might look like jelly being stirred is actually water subjected to 20 times normal Earth gravity within ESA's Large Diameter Centrifuge—as part of an experiment giving new insight into the behavior of wave turbulence.

A new way to measure cosmic black holes

Supermassive black holes are the largest black holes, with masses that can exceed a billion Suns. Just this spring, the first-ever image of the supermassive black hole at the center of the Messier 87 galaxy was taken, and ...
