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.
"This is one of the most exciting results from Solar Orbiter so far."
Earth just experienced a rare S4 solar radiation storm, the most intense since 2003 — powerful for satellites and astronauts, but harmless on the ground.
Aurora alert! The colossal solar storm could impact and trigger impressive northern lights.
NASA's Parker Solar Probe captured solar material looping back to the sun, revealing how it recycles magnetic energy and shapes future solar storms.
Scientists have created the first detailed maps of the sun's atmospheric boundary, where solar material breaks free and streams into space.
The powerful X1.1 solar flare from sunspot region 4298 sparked strong radio blackouts on the sunlit portion of Earth at the time of eruption.
What can today's scientists learn about astronomical phenomena from ancient texts?
