According to NASA, matter in a neutron star is so tightly packed that a sugar-cube-sized amount of neutron star material would weigh more than 1 billion tons — roughly the weight of Mount Everest.The National Aeronautics and Space Administration (NASA) recently shared a picture of a neutron star in the middle of a supernova remnant, leaving netizens in awe.
The picture, which was posted on the Instagram account of NASA’s Chandra X-ray Observatory, features the neutron star, as a bright source, at the centre of supernova remnant RCW 103.
