This awesome video shows the constant stream of material that the Sun throws out into the solar system. It was produced using the classifications from citizen scientists on the Solar Stormwatch project. The video covers three years of observations from STEREO (Solar TErrestrial RElations Observatory). Every so often we see a coronal mass ejection (a.k.a. solar storm), where the Sun spews out a huge amount of matter. When the Earth is in the firing line of these storms there can be serious consequences, such as the disruption of power grids and damage to satellites. On the other hand, they also produce beautiful aurorae (northern/southern lights).
