This is from NASA’s STEREO B Spacecraft. There are a few extremely interesting aspects of this video.
- You can observe 4 of Jupiter’s large moons, Io, Europa, Ganymede, and Callisto orbiting Jupiter, while Jupiter is orbiting the sun.
- You can see a burst of plasma burst out from the sun, called a coronal mass ejection. This ejection is going thousands of kilometers an hour and consists of billions of tons of plasma (Thanks to Phil Plait for info).
- This spacecraft is actually two separate craft viewing a different angle of the sun, to create a 3-D image for the astrophysicists to study.
