A Solar Prominence Eruption from SDO
Explanation: One of the most spectacular solar sights is an erupting prominence. In 2011, NASA's Sun-orbiting
Solar Dynamic Observatory spacecraft imaged an
impressively large prominence erupting from the surface. The
dramatic explosion was captured in ultraviolet light in the
featured time lapse video covering 90 minutes, where a
new frame was taken every 24 seconds. The scale of the prominence is huge -- the entire
Earth would easily fit under the flowing
curtain of hot gas. A
solar prominence is channeled and sometimes held above the Sun's surface by the Sun's
magnetic field. A quiescent prominence typically lasts about a month, and may erupt in a
Coronal Mass Ejection (CME)
expelling hot gas into the
Solar System. The energy mechanism that creates a
solar prominence is still a topic of
research. After our Sun passes the current
Solar Minimum,
solar activity like
eruptive prominences are expected to become more common over the next few years.
