A hypnotic new NASA video shows a solar filament erupt, causing explosions and then forming a series of giant magnetic arches of solar material, all of which ultimately collapse into the sun.
“The arches of solar material appear to glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along the sun’s magnetic field lines,” the space agency said in a news release.
Solar filaments are arcs of plasma in the sun’s atmosphere, which appear as dark lines because they’re not as hot as the rest of the sun, according to the University Corporation for Atmospheric Research.

The sun’s peak of solar activity this year will likely be the quietest seen in at least 100 years, say NASA scientists who watch Earth’s closest star daily.
Sunspot numbers are low, researchers said, even as the sun reaches the peak of its 11-year activity cycle. Also, radio waves that are known to indicate high solar activity have been very subdued.
“It’s likely to be the lowest solar maximum, as measured by sunspot ‘number,’ in more than a century,” wrote Joe Gurman, a project scientist for NASA’s sun-observing mission Stereo, or Solar TErrestrial RElations Observatory. The current sun weather cycle is known as Solar Cycle 24.
