astronomers witnessed the bright light was emanating from the room where the collision Neutron Stars . The first detection of this light occurred three years ago. From a distance of 130 million light years, astronomers witnessed brilliant flashes of gamma radiation, marked by gravitational waves rippling as the two dead stars unite.

Since then astronomers have kept a close watch on the corner of the space where the collision occurred to see what happened after it. Then, to their surprise, they discovered that the light continued to glow in the X-ray spectrum long after it was thought that such radiance would cease.

"We really don't know what to expect from now on, because all our models predict no X-rays and we were surprised to see them 1,000 days after the collision event was detected. It may take years to figure out what is going on. , but our research opens the door to many possibilities, "said astronomer Eleonora Troja of the University of Maryland, as quoted by Science Alert , Tuesday (13/10/2020).

The collision event, named GW170817, was first detected on August 17 2017 as a gravitational wave emitting from part of the sky in the Hydra Constellation, thanks to the LIGO-Virgo gravitational wave detector.

Then in just 1.7 seconds two space-based observatories, NASA's Fermi Gamma-Ray Space Telescope and the ESA's National Gamma-Ray Astrophysics Laboratory, discovered an intense burst of gamma rays, the brightest and most energetic event in the universe.
