Nicknamed the Jellyfish Nebula by some astronomers for its seemingly dangling tentacles, this faint nebula in Gemini (appearing close to M35) is, in fact, the remnant of a supernova, the violent death of a massive star, which occurred sometime in the last 10,000-30,000 years. The nebula is about 5,000 light years distant.
This image combines subexposures of 300 and 400 seconds taken on January 10, 12, 20 & 22, for a total exposure time of 235 minutes, or just under four hours.
