Chinese radio telescope finds hundreds of new pulsars
After the collapse of the Arecibo radio telescope platform last year, the largest single-dish radio telescope in the world is China's Five-hundred-meter Aperture Spherical radio Telescope (or FAST), and it's been producing some interesting science.
One of its key projects is to survey the sky and map out faint pulsars: Spinning neutron stars that send out beams of energy as they spin. Like a lighthouse, if the beam sweeps over Earth we see a blip, a pulse of energy from them.
