What does a neutron star look like and how does its appearance differ from other celestial objects?

A neutron star looks like a dense, compact ball of neutrons formed from the collapsed core of a massive star after a supernova explosion. Its appearance differs from other celestial objects because it's incredibly small yet extremely dense, packing the mass of about 1.4 suns into a ball only 12 miles wide. In other Words, it's a celestial pint-sized powerhouse that doesn't mess around.
