Using an array of ground and space-based telescopes, including the NASA/ESA/CSA James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and...
Gamma-ray bursts (GRBs) come in two varieties, long and short. Long GRBs, which last a couple of seconds to one minute, form when a star at least 10 times...
The binary neutron-star merger GW170817 was discovered in August 2017. Many telescopes saw different kinds of light after the discovery, but only NASA’s...
Several billion years ago, a short gamma-ray burst unleashed more energy in a half-second than our Sun will produce over its entire 10-billion-year lifetime....
Astronomers using ESO’s Very Large Telescope (VLT) have detected a freshly made heavy element, strontium, in the aftermath of GW170817, a merger of two...
Astronomers have re-examined data from GRB 160821B, a short duration gamma-ray burst spotted on August 21, 2016, and found evidence for a kilonova, an...
A distant relative to GW170817, the first source identified to emit gravitational waves and light, has been discovered. Reported in the journal Nature...
For the first time, astronomers have observed the source of gravitational waves, created by the merger of two neutron stars. The cataclysmic aftermaths...
