STEREO (Solar TErrestrial RElations Observatory) Ahead is one of two identical spacecraft launched to enable stereoscopic imaging of the Sun. The spacecraft caught this spectacular eruptive prominence as it blasted away from the Sun April 12, 2010. This was among the largest prominence eruptions seen by either the STEREO or SOHO spacecraft. The length of the prominence appears to stretch almost halfway across the sun, about 500,000 miles. Prominences are cooler clouds of plasma that hover above the Sunís surface, tethered by magnetic forces. They are notoriously unstable and commonly erupt as this one did in a dramatic fashion.
