Description

The Jellyfish nebula is a supernova remnant in the constellation of Gemini. Located around 5000 light years away, its exact age is unknown, but it appears to have blown at least 3000 years ago, possibly much longer.

Imaged here in two narrowband wavelengths, Hydrogen Alpha (7nm) and Oxygen III. The Ha emission is dominant, but there are tantalising glimpses of Oiii at the extremities.
