gamma–crucis:

The Crab Nebula is a supernova remnant and pulsar wind nebula found in the constellation of Taurus. At it’s center lies a neutron star 28-30km across, that emits radiation from gamma rays to radio waves. It is not visible to the naked eye, but can be seen using a telescope or binoculars.
