Description

This beautiful object is a supernova remnant located 5000 light years away in the constellation of Gemini. The appropriately nicknamed Jellyfish Nebula spans about 70 light-years and its apparent size is twice that of our full moon. This image shows the hydrogen, oxygen, and sulfur gas fronts leftover from the violent explosion. The remnants of the now dense neutron star which originated the explosion are located in the center of the image.

Supernova remnants are one of my favorite deep sky objects. In this image, I really like the narrow dark lanes which wind through the relatively sparse central area of the nebula, as well as the red and cyan emission glows which are radiating out of the nebula to the upper right. Much of the central area is obscured by a large molecular cloud in the foreground which extends from upper left to lower right.
