Nchịkọta: ESOcast 46 is the sixth special episode of this series. It describes how state-of-the-art cameras and spectrographs help ESO’s powerful telescopes collect and analyse the faint light from the distant Universe. Without these instruments, ESO’s eyes on the sky would be blind. Today’s astronomical images are very different from those from the 1960s. Back then, astronomers used large photographic glass plates, which were not very sensitive and hard to handle. Nowadays, ESO’s telescopes use some of the largest and most sensitive electronic detectors in the world. They catch almost every cosmic photon and recover almost every possible bit of information. For instance, the VLT Survey Telescope’s camera — OmegaCAM — has 32 detectors, which team up to produce spectacular images of the Universe, each with an impressive 268 million pixels. But astronomy is not only about taking breathtaking images.
