Researchers analyzing crimson auroras over Japan found the glowing displays stretched hundreds of miles higher into Earth's atmosphere than expected, challenging long-held assumptions about the strength of geomagnetic storms.
Scientists studied how space junk moved in orbit over a 36-year span, finding that increased solar activity caused it to fall to Earth faster.
The twin eruptions briefly disrupted radio signals across the dayside of Earth.
Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.
"In the inner corona, a region very difficult to observe, we saw slow solar wind gusts moving three to four times faster than expected."
An X1.4 solar flare triggered radio blackouts and launched a fast CME as NASA prepares for its Artemis 2 moon mission.
The powerful magnetic field belonging to the sun is generated far beneath the visible surface.
The sun's visible disk has been perfectly free from sunspots for the first time since June 2022, suggesting the current solar cycle might be heading toward its quieter phase.
An impulsive X4.2 solar flare sparked strong radio blackouts across Africa and Europe as the giant sunspot continues to rage.
A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense X8.3 eruption.
