IC 443, the Jellyfish Nebula |
 |
Sometime between 3,000 and 30,000 years ago
(the time frame has not been narrowed down yet), a supernova
went off in the constellation Gemini. Today, telescopes aimed at
that region can still see the remains of that blast scattering
about. This glowing cloud of gas and dust has been cataloged as
IC 443.
IC 443, or the Jellyfish Nebula, is the brighter cloud to the
lower right of this image, resembling its namesake quite nicely.
The dimmer, larger nebulosity above and to its left is the
unrelated emission nebula Sharpless 249. Both objects are pretty
dim, and I have not tried viewing either of them visually. |
