Jan. 19, 2015, was a red letter day for NASA's Solar Dynamics Observatory -- one of its instruments, having continually stared at the sun for 5 years, captured its 100 millionth observation of our nearest star.
Eruptions on the sun's surface are probably caused by giant, unstable magnetic plasma arches, a new study reports — a discovery that brings scientists one step closer to predicting solar outbursts that can wreak havoc on Earth.
Just as the US prepares to watch the partial solar eclipse today, nearly 100 million miles away on the sun a possible solar storm is brewing. Continue reading →
A huge arc of plasma has been imaged rising from the sun's surface by a NASA solar observatory, producing a beautiful view of the sun's magnetic dynamics in action. Continue reading →
For the first time, a massive solar flare revealed the process that created it, confirming new theories about flares and the explosive ejections of solar material often linked with them.
As the recent X4.9-class flare ripped across the surface of the sun, a fleet of solar observatories were ready to measure its impact.
Inspired by a prehistoric material used by our ancestors to create cave drawings 30,000 years ago, scientists have found an ingenious method to keep the upcoming European Solar Orbiter cool. Continue reading →
A massive solar flare has delayed Orbital Sciences' Antares rocket launch, pushing the space station cargo run to later in the week. Continue reading →
