transient astronomical events
Transient astronomical events are brief, often spectacular phenomena observed in the universe that last from seconds to months. Examples include supernovae (explosive deaths of stars), gamma-ray bursts (intense energy emissions), and asteroid impacts. These events reveal dynamic processes and changes in celestial objects, offering insights into the lifecycle of stars, galaxy evolution, and cosmic physics. Because they are temporary, astronomers use specialized telescopes and surveys to detect and study them quickly, helping us understand the universe's ongoing and often dramatic transformations.
