Earth grew an extra, never-before-seen 'radiation belt' after last year's supercharged solar storm — and it's probably still thereData 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.

Potentially deadly 'chirping waves' detected in baffling location near Earth, and scientists are stumpedChorus 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.

Extremely rare, black 'anti-auroras' paint luminous 'letter E' above AlaskaA "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.

Scientists detect the most powerful cosmic rays ever — and their unknown source could be close to EarthNew 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.
