Pulsars

A pulsar is the remnant of a massive star whose core has collapsed, in a supernova explosion, to a dense, quickly rotating body about 10 miles across with radiation from magnetic poles that sweeps through space like a lighthouse. Wolfram|Alpha offers information on radiation, rotation, distance and motion, discovery year, equatorial location, nearby sky objects and the current sky position for pulsars.
