The Jellyfish Nebula – also known as IC 443 and Sh2-248 – is a supernova remnant located 5,000 lightyears away.
The glowing cosmic tendrils and fat bulbous ‘head’ are what give this deep-sky object its name, as it resembles a cosmic jellyfish floating through the Universe.
The Jellyfish Nebula is all that remains of a massive star that ran out of fuel and exploded as a supernova, leaving behind a shell of glowing gas.

Studies with the Chandra X-ray Observatory suggest that the explosion may have created a spinning neutron star known as a pulsar in the southern edge of the nebula.
Yet while it was the collapsing of a dying star that produced the Jellyfish Nebula, some of the leftover material may well coalesce and grow over time, eventually producing new stars and perhaps even new planetary systems.
