Solar Prominence Eruption Captured on Video

Solar Prominences are amazing ejections of solar matter caused by the ever-changing magnetic field of the Sun. These events launch millions of tons of material away from the sun, and can sometimes result in very damaging electrical storms once the ejecta makes it's way to the Earth and collide with the earth's own magnetic field.

The twin STEREO spacecraft have captured one such ejection. The STEREO spacecraft are two separate but identical satellites which are positioned one WAY in front and one WAY behind the Earth as it orbits around the Sun, so, in essence, they follow the same orbit path as us. By positioning these instruments there, it is possible to capture a stereoscopic vision of solar prominences and ejecta, as well as any other solar events that may occur. Enjoy the short clip below.
