Neutron Stars To Be Used For Intergalactic Travel Navigation

Neutron stars are the remnants of a dying supernova explosion that rotate fast and emit beams perceived as radiation pulses when pointed towards the Earth. The X rays of these pulsars are to be used to graph the route of a spacecraft (now a satellite) in the intergalactic space. This ground-breaking technology, developed at Max Planck Institute (Germany) allows to monitor the path of the spacecraft anywhere in the solar system or galaxy, as the pulses are produced at regular time periods gap.
