Overview
Advanced view of Light Curves, Time-Domain Astronomy & Transients
Time-domain astronomy studies how brightness, spectrum, or position changes with time. A light curve turns repeated measurements into a record of variability, revealing periodic stars, eclipses, transits, flares, supernovae, tidal disruption events, and other transient phenomena.
Time-domain data discover exoplanets, supernovae, variable stars, compact-object events, near-Earth objects, and unexpected phenomena.

supported · checked Sep 22, 2026Different physical processes create characteristic time signatures: orbital geometry produces eclipses, stellar oscillations create pulsations, explosions produce rise-and-decay curves, and rotating spots modulate brightness.
supported · checked Sep 22, 2026TESS continuously monitors changing sources in broad sky sectors, while Rubin's LSST repeatedly surveys the southern sky to detect and classify enormous numbers of changing or moving objects.
