Astronomers have discovered the slowest spinning radio wave-blasting neutron star ever seen; it takes almost an hour to complete a full rotation.
A NASA animation depicts the super-bright and super-young pulsar J1823-2021A, which is the brightest and youngest pulsar yet discovered, and has a powerful magnetic field. The pulsar spins about 183.8 times a second, which causes them to beam out highly collimated radio waves from their poles. As these neutron stars spin, the beams sweep across the cosmos, making pulsars almost akin to celestial lighthouses.
"It is highly unusual to discover a neutron star candidate emitting radio pulsations in this way. The fact that the signal is repeating at such a leisurely pace is extraordinary," team leader Manisha Caleb of the University of Sydney Institute of Astronomy."What is intriguing is how this object displays three distinct emission states, each with properties entirely dissimilar from the others.
