Sun Unleashes 'Double Prominence' Monster Eruptions (Video)
November 17, 2012
The Sun erupted with two prominence eruptions, one after the other over a four-hour period on Nov. 16, 2012, between the hours of 1 and 5 a.m. EST. The red-glowing looped material is plasma, a hot gas made of electrically charged hydrogen and helium. 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.
