GW170817, a titanic collision between two neutron stars detected in August 2017, ejected a structured relativistic jet with a speed greater than 99.97%...
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...
In 2017, astronomers detected a gravitational-wave signal, designated GW170817, from the merger of two neutron stars. And since the detection, they have...
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...
The Hubble constant measures the current expansion rate of our Universe and plays a fundamental role in cosmology: it can be used to determine the Universe’s...
A distant relative to GW170817, the first source identified to emit gravitational waves and light, has been discovered. Reported in the journal Nature...
Radio observations using a combination of NSF’s Very Long Baseline Array, the Karl G. Jansky Very Large Array and the Robert C. Byrd Green Bank Telescope...
A new study using X-ray data from NASA’s Chandra X-ray Observatory indicates that the neutron star merger that became the gravitational wave source,...
Origin of Universe’s heavy elements, ranging from gold to uranium, has finally been confirmed, after a gravitational wave source was seen and heard for...
For the first time, astronomers have observed the source of gravitational waves, created by the merger of two neutron stars. The cataclysmic aftermaths...
