Ten thousand years light years away, deep in the rich star clouds of the Southern Milky Way, in the constellation of Norma*, a high-mass star ran out of nuclear fuel.
It’s core collapsed and the star exploded. It was a type II supernova.
The light first reached us two thousand years ago. No, dear reader, it wasn’t the so-called star of Bethlehem.
. . . well, not quite.
Dense because neutron stars have a mass of about 1.4 solar masses squeezed into a diameter of only about of 20 kilometres. Unusual because it seems to be rotating too fast for a neutron star so young. Astronomers like a puzzle.
*The Norma constellation was not named after an astronomer’s lady friend. It was named after a carpenter’s square.
