Given the vastness and wealth of the universe from countless stars, Hubble has captured its share of supernova images, and it is estimated that stars explode at a rate of about one per second across the universe.
In February 2018, Hubble began monitoring a supernova that was discovered a few weeks ago by amateur astronomer Koichi Itagaki, a supernova called SN 2018gv, seen in a spiral galaxy 70 million light-years away.
This means that the light emitted from this event took 70 million years to reach us, so we are actually seeing a supernova from the distant past.
The supernova emitted as much energy in days as our sun does over several billion years, or radiation from 5 billion suns, and the light of the explosion was brighter than the light of the host galaxy and more.
The stars shine brightly in the galaxy.
This happened after a white dwarf or dead star had pulled material away from its companion star. This caused the gas surge that served as the ignition of a thermonuclear explosion and effectively transformed the white dwarf into an atomic bomb.
Then, astronomers watched the supernova fade into nothingness over the course of nearly a year. Hubble released a new time-lapse video on Thursday compressing this in a few seconds.
Nobel Prize winner Adam Rees said in a statement: “No terrestrial fireworks display can compete with this supernova captured in its fading glory by the Hubble Space Telescope.”
