A group of German investigators at the Max-Planck Institute for Extraterrestrial Physics (MPI-EP), in Garching, say that navigating through deep space requires the use of other “beacons” than stars, planets and constellations. They propose that pulsars may constitute this new generation of space beacons.

Some of the massive stars in the Universe are destined for great things after they reach the end of their burning cycles. Rather that fizzling out and turning into a white dwarf, or collapsing into a massive black hole, they convert their core into a fast-spinning type of structure called a neutron star. These object... |

Pulsars are neutron stars left behind after a massive supernova explosion. After everything clears, all that remains is the core of the formerly massive star that blew up, which is now shedding neutrons, while spinning very fast around its own axis. They are called pulsars because the jets of radiation they are elimi... |

One may argue that the comparison between the two distinctive entities is greatly overexaggerated.

Both contain matter in a rel... |
