From Space.com:
Telescopes all over the world and in space were busy on Aug. 17, when scientists made the first-ever observations of both light and gravitational waves from a single cosmic event. Here are some of the stunning images of the event, including some from the Hubble Space Telescope, as well as artists' illustrations that give insight into the complex workings of this energetic collision.
The eruption of light and gravitational waves (ripples in the universal fabricknown as space-time) was produced by an event known as a kilonova, or the collision and merger of two neutron stars, which are the dead cores of stars that stopped burning fuel. This is the first time scientists have directly observed a kilonova eruption, scientists said during a news conference today (Oct. 16).
Astronomers at today's news conference said that this detection of both light and gravitational waves marks the beginning of the era of multimessenger astrophysics, which means studying the cosmos with fundamentally different types of information, such as gravitational waves and light.
