Neutron stars don't get much attention these days. They're not as notorious as black holes, nor as capable of fully warping spacetime. But this story really started before dawn on July 4, 1054, when a new brilliant star abruptly appeared near the left horn of Taurus the Bull, very close to where the Sun is located during the next few weeks. It was seen in broad daylight for more than a month. Good backyard telescopes show this as the remnant of an exploded star 6,500 light-years away, whose tendrils still rush outward at a thousand miles a second, visibly altering the nebula every few years.
