The sunspot that is likely responsible for a monster solar flare that exploded into space yesterday is visible to skywatchers with a pair of solar-viewing glasses.
Early this morning (Sept. 6) the sun released two powerful solar flares — the second was the most powerful in more than a decade.
What's powering the powerful auroras at Jupiter's poles? New results suggest it's not the same mechanism powering the most energetic auroras on Earth, contrary to scientists' expectations.
People as far south as Ohio and Indiana may be able to see the northern lights Wednesday night (Sept. 6), thanks to a powerful sun storm.
On Oct. 14, 2014 the Sun blew off a coronal mass ejection (CME) and was detected by the Solar and Heliospheric Observatory (SOHO) and other NASA/ESA probes.
