Two years ago, a type IA supernova event called SN 2022ABVVT was discovered in Spiral Galaxy LEDA 132905.

LEDA 132905 in the sculptor’s constellation is over 400 million light years away.
“The galaxy’s spiral structure, resembling a bright blue star patch, appears faint,” said members of the Hubble team.
“The bright white dot between the bright center of the galaxy and the faint left end is the SN 2022ABVVT supernova.”
The supernova SN 2022ABVT was discovered in 2022 by astronomers of the asteroid landlady impacted alert system (ATLAS).
About two months later, the NASA/ESA Hubble Space Telescope observed the star explosion.
“Atlas, designed to track faint-moving signals from asteroids near Earth, also detects objects that suddenly become brighter or fade, like supernovae in the centers of galaxies, various stars, and hungry black holes,” astronomers explained.
This Hubble image of LEDA 132905 was captured using the Hubble wide field camera 3 (WFC3) in the infrared part of the spectrum.
Astronomers are interested in studying type IA supernovae, which occur when the exposed core of ancient stars ignites in a sudden and destructive nuclear fusion burst.
These supernovae are valuable for measuring accurate distances to other galaxies.
“The universe is vast, and supernova explosions are faint,” researchers stated.
“How can we be in the right place at the right time to observe a supernova?”
“Today, most supernovae are discovered by robot telescopes constantly scanning the night sky.”
“However, some are still found the traditional way, with diligent observers taking repeated images of the sky and searching for any changes.”
