A rapidly spinning neutron star — a pulsar — sweeps two narrow, opposite beams of radiation like a lighthouse, surrounded by a glowing accretion disk of hot gas. The beams are tilted 18° relative to the rotation axis, so from the camera's point of view they flash brighter and then dim — this is exactly how a pulsar's pulsing signal arises in reality. The disk consists of thousands of particles orbiting according to Kepler's law: inner particles move faster than outer ones, and the color shifts from hot yellow-white near the star to cool red-orange at the edge. The star's core periodically pulses in brightness and size, mimicking the relativistic flickering of a neutron star.
