by Astronomers using the NASA/ESA Hubble Space Telescope have tracked the fading light of a Type Ia supernova in NGC 2525, a barred spiral galaxy located approximately 70 million light-years away in the southern constellation of Puppis.
Type Ia supernovae like SN 2018gv originate from a white dwarf in a close binary system accreting material from its companion star.
If the white dwarf reaches a critical mass (1.44 times the mass of our Sun), its core becomes hot enough to ignite carbon fusion, triggering a thermonuclear runaway process that fuses large amounts of oxygen and carbon together in a matter of seconds.
The energy released tears the star apart in a violent explosion, ejecting matter at speeds up to 6% the speed of light and emitting huge amounts of radiation.
Type Ia supernovae consistently reach a peak brightness of 5 billion times brighter than our Sun before fading over time.
