Superluminous Transient Supernova ASASSN-15lh Explosion, Biggest Blast Ever!
Supernova takes place during the last stellar evolutionary stages of an enormous life of the star. It is a catastrophic and dramatic destruction which appeared to be the brightest and slowly fading over several weeks or months. The newly discovered supernova was 20 times as enormously bright as the stars' total light output of the entire the Milky Way.
Recently, the intense explosion that astronomers previously discovered was classified as the brightest supernova which actually might have been caused by the explosive death of a star dragged apart by a giant black hole. Four billion light years away from Earth, the explosion lighted up the entire distant galaxy. It was the peak outshining and slowly faded.
It was the most luminous and twice as bright as any other supernova previously seen. The ASASSN-15lh was the first supergiant star that went super luminous hyper-nova. It was a hundred times brighter than a typical supernova. The All Sky Automated Survey for Super-Novae (ASAS-SN) concluded that the extreme gravitational forces of the supermassive black hole ripped the Sun-like star.
The Weizmann Institute of Science in Israel and the Dark Cosmology Centre in Denmark confirmed that the explosion has a new explanation. Giorgos Leloudas said that the tidal disruption event is only observed about ten times as heat generated in accretion which leads to burst luminous explosion.
The explosion was observed in ultraviolet optical infrared detail over a ten month period using an ESO's new telescope and the Hubble large telescope. The ASASSN-15lh showed an ultraviolet brightening, however, rapid temperature faded out as well. The explosion happened about 3.8 billion light years in the border of the southern constellations Indus and Tucana.
Light illuminates about 570 billion times than the sun. Given enough time and enough quality technology in observations, scientists are expected to see another event that is similarly rare and brilliant. The research was published in the Nature Astronomy magazine entitled, "The Superluminous Transient ASASSN-15lh as a Tidal Disruption Event from a Kerr Black Hole," by G. Leloudas et al."
