A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.
When astronomers observed a neutron star collision in 2017 through telescopes, they found the event could create heavy elements such as gold, platinum and lead.
However, the Chandra observations revealed low X-ray levels. Above, an artist's illustration of GW170817, the neutron-star collision whose gravitational waves were detected in August 2017.
This is why gold is so rare. These neutron star collisions only happen every 100,000 years or so in our galaxy. Not everyone agrees with this scenario because supernovae, giant stars that end ...
Dr. Eleonora Troja, an associate professor at the University of Rome who led the discovery of X-rays emitted by the neutron star collision in 2017, said the evidence for heavy element creation ...
But it's looking good. A recent circular distributed among scientists said they have narrowed down the probability of it being the first neutron star-black hole collision to 99 per cent.
Neutron stars are the leftover cores of exploded stars and the densest known material in the universe. A typical neutron star has a mass a few times the mass of the sun, compressed into a region ...
