NASA’s NICER Delivers Best-ever Pulsar Measurements, 1st Surface Map

A neutron star would not look like a normal spherical object. The mass is so high and the size so small that spacetime is warped in the vicinity of the star and the image you’d see would actually include portions of the *far* side of the sphere. You’d see more than 50% of its surface, making it look larger than it actually is.
