This is the brightest supernova ever seen
2020-04-13
Youre looking at an artists conception of the brightest supernova ever recorded, a celestial explosion so massive it has blotted out the light of its surrounding galaxy, 4 billion light-years away. First discovered at Hawaiis Panoramic Survey Telescope and Rapid Response System observatory in 2016, scientists have spent the past several years studying the event, dubbed SN2016aps. It is perhaps the largest supernova ever seen, a catastrophic explosion that marks the end of a stars life, CNN reports. The colossal SN2016aps likely formed when two smaller stars merged ahead of what astrophysicists refer to as a pulsational pair-instability supernovaa previously theoretical type of supernova that ignites pulsating waves of gas, researchers report today in Nature Astronomy. The team hopes the finding will prompt NASAs new James Webb Space Telescope to look back in time to the deaths of the very first stars in the universe.
