The Jellyfish Nebula
IC 443, also known as Jellyfish Nebula, is a supernova remnant located at 5,000 light years in the constellation Gemini. This supernova has created neutron star CXOU J061705.3+222127, the collapsed core of the exploded star; these neutron stars have a density of 400 million tons per cubic centimer - in other words, the mass of about 1’800 Great Pyramids of Giza fitted in a cube with one centimer side.
Near the top right corner, a small planetary nebula called HoCr1 (Howell-Crisp 1) can be seen. It was found in 2006 by amateur astronomers Michael Howell and Richard Crisp - always fun to find objects we were not expecting in a photo…
Image shot at Barcarena, Portugal (Bortle 8) from Jan.22 to Jan.28 2023 and built as a modified HSO with RGB stars.
