Data collected from a once-defunct NASA satellite show that Earth grew two extra radiation belts following a supercharged geomagnetic storm in May 2024, including a never-before-seen structure that is "likely still there today," researchers say.

Chorus waves are mysterious, chirping signals produced by spiraling plasma inside our planet's magnetic field. But a new detection suggests scientists may understand less about them than first thought.

A "bizarre" E-shaped aurora was recently photographed dancing in the sky above Alaska. The unusual light show was caused by rare black auroras, a.k.a. anti-auroras, which catapult charged particles from the sun back out of Earth's atmosphere and into space.

New research reports the most powerful cosmic rays ever detected. Because the rays lose energy as they travel through space, their detection at high energies means they are likely coming from sources relatively close to Earth.

Scientists have created the world's fastest microscope, which they hope will answer fundamental questions about how electrons behave.

Scientists have observed an unexpected new behavior in a superconducting material. If physicists can figure out the cause, it could help them to find room-temperature superconductors.

The element bismuth can "float" between magnets due to magnetic levitation. What's the science behind this phenomenon?

The reason for copper's unique properties comes down to the configuration of its electrons.

Researchers are developing a real-life tractor beam, with the goal of pulling defunct satellites out of geostationary orbit to alleviate the space junk problem.

The trio devised methods for creating the tiniest slices of light.
