A supernova brighter and largerthan any other on record has been discovered by scientists at the Center for Astrophysics, a collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. A supernova is an extremely bright and powerful explosion of a dying, massive star that's at least five times the mass of the sun, according to NASA. Enormous stars burn large amounts of nuclear energy at their cores, which in turnmakes the centers very hot. The heat generates outward pressure that prevents the star from collapsing. However, that pressure has something to fight against asa star's gravity tries to compact it into the smallest, tightest ball possible. When a star runs out of energy, and thus heat, the pressure drops and gravity takes over. The star then collapses, creating shock waves that cause the outer part of the star to explode. read more https://www.cnn.com/2020/04/13/world/brightest-supernova-sn2016aps-scn/index.html
