For the first time, astronomers detect gravitational waves from two neutron stars colliding

Once again, scientists have detected gravitational waves — ripples in the fabric of

space and time created by objects moving throughout the Universe. And this time, the celestial signal stems from a never-before-seen event: the merger of two neutron stars. In contrast to past observations of gravitational waves, the event was also detectable by regular light telescopes, giving scientists unprecedented insight into this cosmic collision.                                                                    https://www.theverge.com/2017/10/16/16471616/gravitational-waves-ligo-virgo-neutron-stars-merger-multi-messenger-astronomy
