Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported ...
The most powerful events in the known universe—gamma-ray bursts (GRBs)—are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our sun. ...
