Watch: NASA's Hubble telescope captures exploding star five billion times brighter than the Sun
New Delhi | Jagran Trending Desk: NASA's Hubble Telescope has take a breathtaking snapshot of a self-detonating star in a distant galaxy 70 million light-years away. The space agency recently shared a 30-second video of the celestial event regarded among its top scientific achivements. Such was the brightness of the supernova that it outshone the every other star in the galaxy before fading out of sight.
"No Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope," said Nobel laureate Adam Riess, of the Space Telescope Science Institute (STScI) and Johns Hopkins University in Baltimore.
According to the space agency, the energy released was “equal to the radiance of 5 billion Suns,” a light show worth capturing to be sure. The Hubble telescope first started watching the supernova, named SN 2018gv, in February 2018. The time lapse covers almost a year of observations, the space agency stated.
When a star releases as much energy in just a few days as the Sun does in several billion years, then it does not remain visible for long, the space agency said. However, like “intergalactic paparazzi”, the Hubble Space Telescope was able to quickly capture the supernova.
Notably, comparing the brightness of the supernova with that of the sky helo astronomers in caluculating the distances of their host galaxies. This allows astronomers to measure the expansion rate of the universe. Over the past 30 years Hubble has helped dramatically improve the precision of the universe's expansion rate.
