 Could these be the neutron stars predicted by Z? astronomers nicknamed them pulsars and immediately set their telescopes searching for further clues about them, just a year later, they found one, in the perfect place to put Z's theory to the test.In the winter, we have access to the beautiful part of the sky that contains the constellation of Taurus, here we have the P or the seven sisters, down here we have another cluster of stars which are the H that contain the bright star of A, the angry eye of the bull, and if we follow from A in this direction towards that star there, just about there, we'll find the closest pulsar to the solar system, the crab pulsar.

What particularly excited scientists when they discovered the crab pulsar was that it was buried deep within the remains of a supernova.
In this amazing picture, we see the remnant of a supernova explosion, but when we scan the central part of this nebula, we find the pulsar which is the remnant of the core of the star that exploded.
Now that a pulsar was definitively connected to supernova, scientists realized that they had discovered another of the seven ages of starlight, it showed Swiss astronomer Z was correct all along, his theoretical equations predicted how a supernova could leave behind such a dense remnant.
