Neutron Star Collision detected by LIGO and Virgo for First Time. It shows Origin of Gold

For the first time, scientists have directly detected gravitational waves—ripples in space and time—in addition to light from the
spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light.

The discovery was made using the U.S.-based LIGO, the Europe-based Virgo detector; and some 70 ground- and space-based observatories.

Astronomers pinpoint neutron star collision

Published on Oct 16, 2017

Astronomers at Ligo Observatory in Louisiana have located the neutron star collision that prompted the discovery of gravitational waves. Those waves earned the
lab the Nobel Prize in Physics. A member of that history making team, Duncan Brown, joins CBSN from Syracuse to discuss the importance of these discoveries.

Astronomers announced on Monday that they had seen and heard a pair of dead stars collide, giving them their first glimpse of the violent process by which most of the gold and silver in the universe was created.

The collision, known as a kilonova, rattled the galaxy in which it happened 130 million light-years from here in the southern constellation of Hydra, and sent fireworks across the universe. On Aug. 17, the event set off sensors in space and on Earth, as well as producing a loud chirp in antennas designed to study ripples in the cosmic fabric. It sent astronomers stampeding to their telescopes, in hopes of answering one of the long-sought mysteries of the universe.

Such explosions, astronomers have long suspected, produced many of the heavier elements in the universe, including precious metals like gold, silver and uranium. All the atoms in your wedding band, in the pharaoh’s treasures and the bombs that destroyed Hiroshima and still threaten us all, so the story goes, have been formed in cosmic gong shows that reverberated across the heavens.
