The Jellyfish Nebula is seen dangling tentacles from the bright arcing ridge of emission left of center. In fact, the cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. The Jellyfish Nebula is about 5,000 light-years away. At that distance, this image would be about 100 light-years across.
