IC 443 "The Jellyfish Nebula" and Sharpless 249
About this object
IC 443 or also known as the Jellyfish nebula is the bright red object in the upper center part of the image. Its thought to be a super nova remnant with an expanding debris cloud from a massive star that exploded whose light reached earth 30,000 years ago. With the clouds of this nebula lies a neutron star which is the remnant of the star which exploded. Down on the lower left side of the image is another red nebula called Sharpless 249. Within Sharpless 249 lies a nice small reflection nebula (The blue cloud surrounding a bright star). The star's light reflects off dust clouds in this area causing the blue glow.
