Hubble time! 🌌 A supernova and its host galaxy are the subject of this image. The galaxy in question is LEDA 132905, which is situated in the constellation Sculptor. Even at over 400 million light-years away, LEDA 132905’s spiral structure is faintly visible, as are patches of bright blue stars. The bright white dot directly in the centre of the image, between the bright centre of the galaxy and its faint left edge, is a supernova named SN 2022abvt. SN 2022abvt was discovered in late 2022, and Hubble observed the explosion about two months later. This image was constructed from data collected to study Type Ia supernovae, which occur when the exposed core of a dead star ignites in a sudden, destructive burst of nuclear fusion. Researchers are interested in this type of supernova because they can be used to measure precise distances to other galaxies. The Universe is a big place, and supernova explosions are fleeting. How is it possible to be in the right place at the right time to c...
