ISRO's AstroSat detects first far-ultraviolet emissions from novae in Andromeda Galaxy

ISRO's AstroSat has made a significant discovery by detecting far-ultraviolet emissions from 42 novae in the Andromeda Galaxy. This is the first time such emissions have been observed during the outbursts of these stellar explosions. The Ultraviolet Imaging Telescope (UVIT) aboard AstroSat tracked four novae in real-time as they erupted. Researchers noted that the observations provided insights into the processes leading to these thermonuclear explosions. The study, published in The Astrophysical Journal, emphasizes the importance of these findings for understanding stellar evolution and galactic chemistry. Advanced image processing techniques were used to confirm the observations amid the bright central region of Andromeda.
