Master of The world of neutron stars
artiteacher Pulsars and the cosmic lighthouse
Seven hundred times a second, J-Seventeen-Forty-Eight flashes in the deep.

artiteacher Some pulsars spin hundreds of times per second, rivaling the accuracy of Earth's best atomic clocks.

artiteacher Irish astrophysicist Jocelyn Bell Burnell discovered the first pulsar in 1967, initially wondering if it was an alien signal.

artiteacher Spin the dense neutron star to discover how rapid rotation creates a cosmic lighthouse.
Fast spins: The fastest known pulsar, PSR J1748-2446ad, spins on its axis 716 times every single second.
A rapidly spinning neutron star that emits regular pulses of radio waves and other electromagnetic radiation. Astrophysicist Jocelyn Bell Burnell discovered the first of these highly magnetized, rotating stellar corpses in 1967.
What kind of electromagnetic radiation do we most commonly detect from pulsars?
In what year did Chinese and Arab astronomers record the supernova that created the Crab Nebula?
