Beneath the surfaces of distant planets, microbes might subsist on harsh radiation rather than starlight, a new study suggests

Like birds returning to their nests, these feather-like grid fins help steer rockets back down through the atmosphere toward their landing zones.

Auroras may be visible from Alaska to Washington as an incoming speedy solar wind could spark geomagnetic storm conditions overnight.

Defining the fundamental units of electricity used to require two finicky quantum devices – but now scientists have found an easier way to standardise our electrical measurements

China is having a fast-rising chikungunya outbreak in a place that has never had one before.

A rare August morning alignment brings Mercury, a thin crescent moon and the Beehive Cluster together in the predawn sky. Here's how you can see it for yourself.

Large dark matter particles hitting Jupiter’s largest moon would form distinctive craters in its icy surface, and upcoming space missions might be able to spot them

Space is getting dangerously crowded but a new automated system could be the key to preventing catastrophic collisions that threaten our satellites and astronauts. The European Space Agency has developed CREAM (Collision Risk Estimation and Automated Mitigation), a revolutionary technology that aims to transform how we manage traffic in Earth orbit and keep space safe for future generations.

arXiv:2507.21402v1 Announce Type: new Abstract: The interstellar object 3I/ATLAS is expected to arrive at a distance of $53.56(\pm 0.45)$ million ${\rm km}$ ($0.358\pm 0.003$~au) from Jupiter on March 16, 2026. We show that applying a total thrust $\Delta$V of $2.6755{{\rm km~s^{-1}}}$ to lower perijove on September 9, 2025 and then execute a Jupiter Oberth Maneuver, can bring the Juno spacecraft from its orbit around Jupiter to intercept the path of 3I/ATLAS on March 14, 2026. A close fly-by...
