Neutron stars collision creates gold, light and gravitational waves

Posted by

For the first time, two neutron stars in a nearby galaxy have been observed engaging in a spiral death dance around one another until they collided. What resulted from that collision is being called an “unprecedented” discovery that is ushering in a new era of astronomy, scientists announced Monday.
“We can now fill in a few more tiles in the jigsaw puzzle that is the story of our universe,” said Laura Cadonati, deputy spokeswoman for the LIGO Scientific Collaboration and professor in the school of physics at Georgia Tech.
The collision created the first observed instance of a single source emitting ripples in space-time, known as gravitational waves, as well as light, which was released in the form of a two-second gamma ray burst. The collision also created heavy elements such as gold, platinum and lead, scattering them across the universe in a kilonova — similar to a supernova — after the initial fireball.
