A Stormy Star

Vodpod videos no longer available.

This video from the SOHO solar observatory spacecraft shows a a partial rotation of the Sun seen in ultraviolet light (the green color is from the specialized camera filter, corresponding to emissions at 1.5 million degrees Kelvin.) In the Sun’s northern hemisphere an energetic area of solar prominences can be seen, tens of thousands of miles wide and writhing with magnetically-bound tubes of superhot plasma, which erupt from the sun’s chromosphere and arc out into space before being pulled back onto the surface of the Sun.

Another prominence was caught in action in the video below which was chosen as the SOHO site’s pick of the week. This solar feature, many times the size of Earth, lasted for three days before it dissipated.
