Recently there has been a spotting of what is called a Kilonova. Neutron stars that are super dense remains of exploded stars and the bright afterglow from a collision of the two such objects is known as a Kilonova. There were first signs of this from some telescope data on the date of May 22, 2020 having the best astronomers to assemble their best tools. What made the astronomers get into the deep research of this was because they saw a flash and the flash included far more infrared light than what was predicted in fact it was 10 times more. The telescope that caught images was the Hubble Space Telescope which had the scientists scratching their heads about this new observation.
Edo Berger, an astronomer at the Center for Astronomy jointly run by Harvard University and the Smithsonian and co-author on the new research, said "Surprisingly, we found much brighter infrared emission than we ever expected, suggesting that there was additional energy input from a magnetar that was the remnant of the merger. The fact that we see this infrared emission, and that it is so bright shows that short gamma-ray bursts indeed form from neutron star collisions, but surprisingly the aftermath of the collision may not be a black hole, but rather a magnetar." A magnetar is a cosmic curiosity, an unusual class of super magnetic neutron stars. This being said scientist don't know much information of why these magnetars become so magnetic and this observation is very valuable to the astronomy community.
