In the space of just a few weeks, the LIGO and VIRGO collaborations have announced the fourth detection of gravitational waves and three of their most prominent physicists received a Nobel Prize for their work.
And on Monday they will announce something new.

Merging neutron stars generate gravitational waves and a celestial light show

Four times in the past 2 years, physicists working with mammoth gravitational wave detectors have sensed something go bump in the night, sending invisible ripples through spacetime. Today, they announced the detection of a fifth such disturbance—but this time astronomers saw it too, at every wavelength of light from gamma radiation to radio waves. Just as physicists had predicted, the unprecedented view of the cosmic cataclysm—in which two superdense neutron stars spiraled into each other—brought with it a cornucopia of insights, each of which by itself would count as a major scientific advance.

In A Historic Discovery, A Neutron Star Merger Has Been Observed For The Very First Time

The fifth observation of gravitational waves (GW) marks the beginning of a new era in astronomy. On August 17, 2017, the LIGO and VIRGO collaborations detected neutron stars merging for the first time and immediately alerted observatories around the world. In a matter of minutes the event had been located, another first for GW astronomy, and telescopes around the world begun studying it almost immediately.
The event observed, called GW170817, was produced in galaxy NGC 4993, located 130 million light-years from Earth.

Neutron star collision gives rise to ‘multi-messenger’ astronomy

Astronomers have witnessed a collision between two neutron stars for the first time, thanks to a tie-in between gravitational wave observatories and 70 telescopes around the world.
The event, which allowed scientists to confirm that gold and platinum are formed in such collisions, marks a new approach to astronomy where different forms of observation are used to create a detailed picture of what’s happening.

Scientists detect gravitational waves from a new kind of nova, sparking a new era in astronomy

Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe.
On Aug. 17, those signals reached Earth — and sparked an astronomy revolution.
