The science of moon hopping

The videos of the first moon landing with astronauts bouncing around the lunar surface are looking like a lot of fun—but jumping around on the moon could also be good for astronaut's muscles, bones and the cardiorespiratory ...

James Webb spots swirling, gritty clouds on remote planet

Researchers observing with NASA's James Webb Space Telescope have pinpointed silicate cloud features in a distant planet's atmosphere. The atmosphere is constantly rising, mixing, and moving during its 22-hour day, bringing ...

3D-printed bone for emergency medicine in space

This artificial bone sample is an early step towards making 3D bioprinting a practical tool for emergency medicine in space. An ESA R&D effort aims to develop bioprinting techniques capable of giving astronauts on an extended ...

A stepping stone for measuring quantum gravity

A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves. However, their actual aim is to answer one of the biggest ...

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.

Earth vs. asteroids: humans strike back

Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan's Hayabusa2 spacecraft dropped a copper projectile at very high ...
