Time-domain astronomy is a branch of astronomy that focuses on studying the transient events and time-evolving phenomena in the universe. This area of research involves observing and analyzing changes in brightness, position, and other properties of celestial objects over time. Time-domain astronomy encompasses a wide range of phenomena such as supernovae, gamma-ray bursts, variable stars, and tidal disruptions. By studying these transient events, researchers can gain insights into the dynamic processes occurring in the universe and improve our understanding of astrophysical objects and events.
