IC443 The Jellyfish

ic443mar10

This is a bit of a work in progress, working around the bright moon. It's 10,4 hours of the Jellyfish Nebula, or IC443, as it's known by catalog number. The Jellyfish is a Galactic supernova remnant (SNR) in the constellation Gemini. It is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.

IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

This image was taken the night of February 26-28 and March 3, 5 and 10, 2012. Some of the data was collected during a bright moon, which is not ideal. Click on the image for a closer view.
