Wow! Jupiter and its moons Callisto and Ganymede as seen in the LASCO C2 camera on the ESA/NASA SOHO satellite. Watch the video carefully for the labels to see where the moons are. Also watch for the suicide comet that flashes past. The long "spikes" on Jupiter are imaging artefacts.
Tip of the hat to the Bad Astronomer and Sungrazing Comets on Twitter.
