Mysterious Pulsar and Jellyfish Nebula Share Explosive Birth (Photo)

An explosion in space may have created not only a brilliant nebula but also a rapidly spinning neutron star, according to new data from NASA's Chandra X-ray Observatory. Observations of the Jellyfish Nebula, the remnant of a supernova 5,000 light-years from Earth, show an unusual object located on the southern edge of the nebula. When a massive star implodes, the outer layers of the star collapse inward, exploding into a supernova and leaving behind a dense core called a neutron star.
