From the time of its launch into the space in 1990’s, Hubble Space Telescope is tirelessly helping scientists to explore new dimensions of our vastly unknown universe. In its current endeavor Hubble have witnessed a year long light show during the explosion of a supernova named 2018gv in a large spiral galaxy called NGC 2525.
A white dwarf, which is a very dense remnant of a dead star, was stealing gases from its companion star in a cosmic dance which lasted for years. When the white dwarf could no longer swallow any gas, it exploded in a supernova putting up a stunning show of lights. Our sun would take a few billion years to generate the amount of energy released in the explosion. So, you can imagine the brightness of the light show.
The explosion took place at a distance of about 70 million light years from earth. So, we can say that the snapshots of the supernova explosion captured by Hubble has helped us to view a stunning astronomical event which occurred 70 million years ago in past.
Scientists used the snapshots captured by Hubble from February 2018 to February 2019 to create a time-lapse video of the stunning astronomical event.
Adam Riess who is an astrophysicists at the Space Telescope Science Institute and Johns Hopkins University in Maryland and leader of the team said in a statement, “No Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope”.
