</html><description>Description: Quasar variability refers to the changes in brightness of a quasar over time, which can provide information about its structure. Quasars, which are active galactic nuclei powered by supermassive black holes, exhibit fluctuations in luminosity that can occur on timescales ranging from days to years. These variations are crucial for astronomers, as they allow [&hellip;]</description></oembed>
