Drift into a calm deep-space journey as we move in close to a quasar’s hidden heart. In this long, gentle astronomy documentary, we explore how broad emission lines reveal the motion of gas in the broad-line region, how reverberation mapping uses light-echo time delays to estimate distances, and how hot dust near the sublimation boundary traces the inner edge of the quasar’s dusty structure. Along the way, we connect spectra, time variability, and physical scales to understand the size of the central engine powered by a supermassive black hole—slow, clear, and sleep-friendly.
