First Time That a Cosmic Event is Observed Optically and With Gravitational Waves

First Time That a Cosmic Event is Observed Optically and With Gravitational Waves

For the first time, scientists have directly detected gravitational waves (ripples in space-time) together with the light from a spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed with both gravitational waves and light. The discovery was made using the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US, the Virgo detector in Italy, and some 70 ground and space-based observatories. As two neutron stars spiraled together about 130 million years ago, they emitted gravitational waves that were detected for about 100 seconds on August 17, 2017. In the days and weeks following the initial discovery, a full spectrum of light and electromagnetic radiation from the event (including X-ray, ultraviolet (UV), optical, infrared (IR) and radio waves) were detected and analyzed -- A treasure trove of material that will keep scientist busy for years to come.
