Solar Prominence in Stereo

The STEREO project, a constellation of two identical solar probes, one ahead of the Earth (STEREO A) and one behind the Earth (STEREO B), simultaneously imaged a solar prominence from their divergent perspectives. This video was featured on NASA’s SOHO Pick of the Week.

The video below shows the mass ejection in synchronized timing from ahead and behind the Earth.

In the left panel (behind), you can see the event emerging from near the top of the solar disk, while on the right panel (ahead) it is occurring above the solar horizon. In these times when there are few sunspots, the old solar machine is still cranking out the good old nuclear fusion.
