First, astronomers made history when they detected a gravitational wave from two black holes merging. Then it was two neutron stars. Now, astronomers believe they’ve detected a gravitational wave coming from another first-time discovery: a black hole swallowing a neutron star.
The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates: Continue reading
The collision of two neutron stars, seen in an artist’s rendering, created both gravitational waves and gamma rays. Researchers used those signals to locate the event with optical telescopes. For the first time, scientists have caught two neutron stars in the act of colliding, revealing that these strange smashups are the source of heavy elements such as gold and platinum. Continue reading
