Culmina el diseño final del nuevo instrumento CUBES del VLT
7 de Agosto de 2025
El Espectrógrafo Cassegrain de Banda U Eficiente (CUBES), un futuro instrumento del Very Large Telescope (VLT) de ESO, superó con éxito su Revisión de Diseño Final. Con el visto bueno de ESO para la fabricación del instrumento, el VLT está un paso más cerca de adquirir un ojo ultravioleta dedicado para mirar el cielo. CUBES buscará agua en el cinturón de asteroides y explorará el fondo cósmico ultravioleta, entre otros casos científicos.
ESO acaba de aprobar la construcción de CUBES, un espectrógrafo terrestre capaz de realizar observaciones dedicadas a la radiación ultravioleta o UV a 300-400 nm, una región del espectro luminoso nunca antes explorada con tan alta sensibilidad mediante grandes telescopios. Observar en el ultravioleta desde tierra es increíblemente difícil debido a que la atmósfera terrestre bloquea la mayor parte de los fotones en este rango de luz, mientras que los telescopios espaciales suelen ser demasiado pequeños para poder ver objetos lejanos y tenues en este rango de longitudes de onda. Esto convierte a CUBES en un instrumento revolucionario y muy esperado.
Al contar con la luz verde para la fabricación, el consorcio CUBES -liderado por el INAF, el Instituto Nacional de Astrofísica de Italia- iniciará pronto la construcción. Se espera que el instrumento logre la primera luz dentro de esta década, luego de que se instale en uno de los telescopios unitarios del VLT.
Con CUBES los astrónomos podrán explorar los objetos más tenues en nuestro Sistema Solar, incluidos asteroides y cometas, en el ultravioleta, y así conocer su composición. Los cometas son los restos de la formación de nuestro Sistema Solar y su estudio permite a los investigadores comprender mejor nuestros orígenes. En nuestra galaxia, CUBES ayudará a los astrónomos a determinar la abundancia de elementos clave en las atmósferas de las estrellas con una precisión sin precedentes, mientras que en el espacio extragaláctico, ayudará a desentrañar y estudiar la materia normal (bariónica) que se espera encontrar en el gas que rodea a las galaxias. Además, CUBES está perfectamente adaptado para estudiar el fondo cósmico ultravioleta, una radiación difusa que impregna el espacio entre las galaxias e influye en la formación de las estrellas.
