![]() ![]() Since then, countless GW events have been detected by observatories across the globe – to the point where they have become an almost daily occurrence. ![]() Originally predicted by Einstein’s Theory of General Relativity, these waves are ripples in spacetime that occur whenever massive objects (like black holes and neutron stars) merge. In February 2016, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced the first-ever detection of gravitational waves (GWs). Continue reading “Hubble Examines the Wreckage From the 2017 Kilonova” Using data from Hubble and several radio observatories, a team of researchers detected a rapidly-rotating disk of material around the black hole and a structured relativistic jet emanating from it. However, it would take several more years of analysis before scientists could draw a complete picture of what resulted from this explosive event. Two years later, the Hubble Space Telescopeobserved the remnant and noted the powerful afterglow and gamma-ray bursts (GRBs) created by the merger, which was consistent with a black hole. ![]() The energy released by this merger was comparable to that of a supernova, leading astronomers to theorize that it must have resulted in a black hole. This was the first time astronomers observed a binary neutron star merger in terms of electromagnetic radiation (particularly gamma rays) and GWs. The aftermath of this event (GW170817) was studied by 70 ground-based and space-based observatories in multiple wavelengths. In August 2017, astronomers observed a Gravitational Wave (GW) signal that resulted from the merger of two neutron stars – known as a “kilonova” event. ![]()
