NASA news: Hubble detected flash so bright scientists struggled to explain it – 'Amazing'

This is because these cores are so dense, just a spoonful of their material would weigh billions of tons on Earth.

Astronomers also expect short gamma-ray bursts to be accompanied by kilonovas – the visual and infrared glow from the radioactive decay of heavy elements that is 1,000 times brighter than a regular nova.

In this case, however, Dr Fong and her team speculate an unexpected celestial body may have been born from the merger.

The researchers proposed the neutron stars collided into a magnetar or a star supermassive neutron star with an extremely powerful magnetic field.

Co-investigator Tanmoy Laskar of the University of Bath, UK, said: “You basically have these magnetic field lines that are anchored to the star that are whipping around at about a thousand times a second, and this produces a magnetized wind.
