Summary
| Description |
English: NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy's Office of Science (DOE/SC), is captured here beginning its first night of on-sky observations with the LSST Camera as night settles across the sky. This long-exposure image gives us a great sense of the observatory’s scale, with three people on the gangway in the lower-right corner. Petr Horálek, NOIRLab Audiovisual Ambassador, captured this image during the on-sky commissioning of the camera on 15 April 2025.
The teal telescope mount for Rubin’s Simonyi Survey Telescope was built in Spain and shipped in pieces to its current residence on Cerro Pachón in the foothills of the Chilean Andes. There, engineers and technicians reassembled the mount on the telescope pier inside the observatory over four years, partially amid the COVID-19 pandemic. The mount may look somewhat similar to other telescopes, but it incorporates a unique three-mirror design that makes the entire telescope much shorter and gives it a lower center of gravity. This unique design allows the mount to precisely hold and quickly move the mirrors and LSST Camera, the largest digital camera ever built. The weight of the mount, mirror, and camera totals 350 metric tons (386 US tons). You can get a sense of the speed of the telescope in an earlier NSF NOIRLab Image of the Week and in this time-lapse video.
Español: El Observatorio Vera C. Rubin de NSF–DOE, financiado conjuntamente por la Fundación Nacional de Ciencias de EE. UU. (NSF) y la Oficina de Ciencia del Departamento de Energía de EE. UU. (DOE/SC), aparece aquí en su primera noche de observaciones con la Cámara LSST, mientras la oscuridad se extiende por el cielo. Esta imagen de larga exposición permite apreciar la impresionante escala del observatorio: en la pasarela de la esquina inferior derecha se distinguen tres personas que sirven como referencia de tamaño. La fotografía fue capturada por Petr Horálek,Embajador Audiovisual de NOIRLab, durante la puesta en servicio de la cámara en el cielo, el 15 de abril de 2025.
La montura de color verde azulado del Telescopio de Investigación Simonyi de Rubin se construyó en España y se trasladó por piezas hasta su ubicación actual en Cerro Pachón, en la precordillera de los Andes chilenos. Allí, ingenieros y técnicos la ensamblaron de nuevo sobre el pilar del telescopio dentro del observatorio durante cuatro años, un proceso que continuó incluso durante la pandemia de COVID-19. Aunque a primera vista, la montura puede parecer similar a la de otros telescopios, incorpora un diseño de tres espejos que hace que el telescopio sea mucho más compacto y tenga un centro de gravedad más bajo. Gracias a este innovador diseño, puede sostener con gran precisión y mover con rapidez los espejos y la Cámara LSST, la cámara digital más grande jamás construida. En conjunto, la montura, los espejos y la cámara pesan 350 toneladas métricas (386 toneladas estadounidenses). Para hacerte una idea de la velocidad con la que puede moverse este gigante, puedes ver el telescopio en acción en una edición anterior de laImagen de la Semana de NOIRLab de NSF y en estevideo en cámara rápida. |
