The Sky at Night, Tonight: A New View of the Changing Sky
Chris Lintott, Professor of Astrophysics at Oxford and presenter of the BBC's Sky at Night, surveys what the newly operational Vera Rubin Observatory in Chile has found in its first weeks of scanning the sky. He compares its images against the earlier Sloan Digital Sky Survey to show the leap in scale, explains how astronomers used to compete for scraps of telescope time, and walks through the engineering behind Rubin's billion-dollar camera and mirrors, including storm damage suffered during construction in the Atacama desert. The lecture covers early discoveries already flowing from the survey, among them asteroids, comets, an interstellar visitor, and supernovae, and closes on what the observatory's ongoing scans might reveal about dark matter. Lintott treats the talk as a snapshot of live research rather than settled history, built around whatever the telescope had turned up that particular week.
