Large Eruptive Prominence Imaged by STEREO
Explanation: What's happened to our Sun? Last week, it produced one of the most power eruptive prominences ever seen.
Pictured above, the prominence erupted in only a few hours and was
captured in movie form by NASA's twin Sun-orbiting
STEREO satellites. A quiescent
solar prominence is a cloud of hot
solar gas held above the Sun's surface by the Sun's
magnetic field. Unpredictably, however, prominences may erupt,
expelling hot gas into the
Solar System via a
Coronal Mass Ejection (CME). As pictured above, many
Earths would easily fit under the expanding
ribbon of hot gas. Although somehow related to the Sun's changing
magnetic field, the energy mechanism that creates and sustains a
Solar prominence is still a topic of
research.
