Jellyfish Nebula: In a distance of about  5000 LY, in the constellation of Gemini or The Twins, one finds this faint nebula. Its designation is IC 443, also called Jellyfish Nebula. The intricate patterns and strings are what is left from a Supernova explosion which probably took place more than 30000 years ago and show the shock fronts of this event on the interstellar matter.
The bright star is Propus (Eta Geminorun).

The image was taken at the IAS astronomical site at the Hakos farm in Namibia.

The image has been selected Astrophoto of the Day(APOD).
