time-domain astronomy

Time-domain astronomy is the study of celestial objects and phenomena that change over time. It involves monitoring the universe for variations such as star brightness fluctuations, supernova explosions, or the appearance of transient events like gamma-ray bursts. By observing these changes, astronomers learn about the dynamic processes and physical properties of objects in space. This field relies on repeatedly observing the same regions of the sky to detect and analyze how objects evolve, providing insights into the life cycles of stars, the behavior of black holes, and the nature of cosmic events.
