Jellyfish Nebula
A stunning cosmic sculpture of gas and dust carved by a stellar explosion.
The Jellyfish Nebula, also known as IC 443, is a supernova remnant located in the constellation Gemini. It is the remnant of a massive star that exploded approximately 3,000 to 5,000 years ago, leaving behind a beautiful cloud of ionized gas that resembles a jellyfish in shape. This nebula is particularly interesting due to its interaction with a molecular cloud, resulting in complex structures and emissions across various wavelengths, especially in the hydrogen-alpha and infrared spectra.
