Scientists have observed the source of gravitational weave for the first time, from the collision of two neutron stars, even the space oddity hasn’t stopped there. The team of scientists believes that those neutron stars after collision might have crumpled into the black hole.
The interferometers designed for detecting gravitational waves, i.e. LIGO (Laser Interferometer Gravitational-wave Observatory) and Virgo (Variability of solar IRradiance and Gravity Oscillations) detected a massive signal coming from the galaxy NGC 4993, on 17th August, 2017. The galaxy NGC 4993 is an elliptical galaxy located in the constellation Hydra and discovered by William Herschel in 1789.
The team pinpointed that strange signal in the galaxy and the international collaboration sprung immediately forth to discover the event with space and terrestrial observatories. During the deep observation, the scientists detected a huge brightness from the crash of those two neutron stars across the whole electromagnetic spectrum. The beginning of this great event included the gamma rays of high energy and a few seconds later, they detected the gravitational waves.
A leading research scientist, David Shoemaker from the MIT, who is also a spokesman of the LIGO Scientific Collaboration, stated in a news conference in the National Press Club in Washington, DC on Monday 16th October that, “We don’t actually know what happened to the objects at the end. We don’t know whether it’s a black hole, a neutron star or something else.”
An astrophysicist, Raffaella Margutti from the Northwestern University stated that, “There’s nothing obvious … that would tell us that the remnant was a black hole or neutron star. Once the light is off, we will never see it again.”
