On Sept. 8, 2010, a C3-class solar flare erupts from the Sun. Just as a sunspot was turning away from Earth on Sept. 8, the active region erupted, producing a solar flare and a fantastic prominence. The eruption also hurled a bright coronal mass ejection into space

Astronomy Picture of the Day
Explanation: Imagine a pipe as wide as a state and as long as the Earth. Now imagine that this pipe is filled with hot gas moving 50,000 kilometers per hour. Further imagine that this pipe is not made of metal but a transparent magnetic field. You are envisioning just one of thousands of young spicules on the active Sun. Pictured above is one of the highest resolution image yet of these enigmatic solar flux tubes. Spicules line the above frame of solar active region 11092 that crossed the Sunlast month, but are particularly evident converging on the sunspot on the lower left. Time-sequenced images have recently shown that spicules last about five minutes, starting out as tall tubes of rapidly rising gas but eventually fading as the gas peaks and falls back down to the Sun. What determines the creation and dynamics ofspicules remains a topic of active research.  Full size
