About 30,000 years ago a star explode and sent glowing debris rocketing through the surrounding space. Astronomers call it the Jellyfish Nebula, the remains of a super nova, about 5,000 light years from Earth located in the constellation Gemini. It has a two-layer shell-like structure nearly 70 light years across. In the northwestern portion, is a shock wave, a bright, complex lattice of glowing hydrogen filaments. Extending from this region are meandering streamers of gas and dust extending 25 light years, ejecta of star material.
