The Jellyfish Nebula (officially known as IC 443) is a supernova remnant about 5,000 light years from Earth. Astronomers have been looking for the spinning neutron star, or pulsar, from the explosion that created the remnant. New Chandra observations have likely spotted a pulsar on the southern edge the Jellyfish Nebula. The X-ray data also provide new details about the structure and properties of this pulsar.
