The Jellyfish Nebula (IC 443) is the remnant of a supernova explosion in the constellation Gemini. One of those objects whose shape easily invites debate: some see a brain here, others a heart.
For many thousands of years, the shock wave has been interacting with the surrounding interstellar hydrogen — heating it, tearing it apart, slowing it down, and in places twisting it back on itself. As a result, the nebula takes on an uneven, ragged shell-like structure, resembling wisps of cotton stretched across the dark sky.
In the background lie delicate traces of dust and several small reflection nebulae, unrelated to the supernova itself. There is no “clean” background here — space is filled with matter that the object is forced to interact with.
