Nov. 18, 2012 — The sun unleashed a monster eruption of super-hot plasma Friday (Nov. 16) in back-to-back solar storms captured on camera by a NASA spacecraft.

The giant sun eruption, called a solar prominence, occurred at 1 a.m. EST (0600 GMT), with another event flaring up four hours later. The prominences was so large, it expanded beyond the camera view of NASA's Solar Dynamics Observatory (SDO), which captured high-definition video of the solar eruption.

In the video, a colossal loop of glowing red plasma erupts from the lower left of the sun, arcing up and out of frame as it blasts away from the star.

"The red-glowing looped material is plasma, a hot gas made of electrically charged hydrogen and helium," officials with NASA's Goddard Space Flight Center, which oversees the SDO mission, explained in a description. "The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma."
