Alien planet and pulsar. Computer illustration of a view across the rocky surface of an alien planet towards a pulsar in the background. Pulsars are highly magnetized,rotating neutron stars that emit a beam of electromagnetic radiation. The radiation can only be observed when the beam of emission is pointing towards the viewer. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name | |
