Tens of millions of years ago, the corpse of a star stole away too much gas from a neighbor and exploded, becoming a beacon in the cosmos — one that took a full year to fade away.
Fortunately for scientists, the massive stellar explosion, called supernova 2018gv, took place 70 million light-years away, and the Hubble Space Telescope was in prime position to watch the lightshow. Astronomers used the instrument to create a timelapse showing the supernova’s year-long fade, from February 2018, shortly after the explosion was first detected, through February 2019.
“No Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope,” Adam Riess, an astrophysicist at the Space Telescope Science Institute and Johns Hopkins University in Maryland and leader of the team behind the new footage, said in a statement.
