Graceful Eruption

A mid-level flare, an M6.5, erupted from the sun on April 2, 2014, peaking at 10:05 a.m. EDT. This video from NASA's Solar Dynamics Observatory shows the flare in a blend of two wavelengths of extreme ultraviolet light: 304 Angstroms and 171 Angstroms, colorized in yellow and red, respectively.

Image above: Powerful magnetic forces above an active region on the Sun twisted and pulled at a blob of plasma until it lost its connections and blew out into space (Mar. 26, 2014). The resultant swirling presented its own kind of graceful, almost ballet-like bends and sweeps. To offer some kind of size perspective that blob, before it broke away, was easily larger than several Earths. The event was observed in extreme ultraviolet light over about 5.5 hours beginning at 7:00 UT. The still image was taken at 10:45 UT. Credit: Solar Dynamics Observatory/NASA.
