However, since supernova explosions are asymmetrical, the rate of rotation of the core can be accelerated to ridiculous rates, and the fastest rotating neutron star known, PSR J1748-2446, rotates at a speed of more than 700 times per second, which equates to a speed at its equator of 70...

fuel forming a red giant star that eventually collapses forming a planetary nebula, and finally a white dwarf star. Massive stars become super red giants after burning their fuel and then undergo a supernova explosion that results in the formation of either a black hole or a neutron star. ...
The 12-inch-wide (30 centimeters), gold-plated copper disks also included pictorials showing how to operate them and the position of the sun among nearbypulsars(a type of fast-spinning stellar corpse known as aneutron star), in case extraterrestrials someday stumbled onto the spacecraft and ...
