Telescopios en forma de seta captan señales cósmicas
En esta Imagen de la Semana, bañadas por la tenue luz del atardecer, parece que estén creciendo setas en la cima del Observatorio La Silla de ESO, en Chile. Pero… ¡no se trata de setas, sino de telescopios! A la izquierda se encuentra el telescopio danés de 1,54 metros y, a la derecha, los tres telescopios del conjunto de telescopios BlackGEM.
El telescopio danés de 1,54 metros cuenta con más de 40 años de investigación astronómica a sus espaldas. Observó por primera vez la luz visible asociada con eventos energéticos rápidos conocidos como estallidos cortos de rayos gamma, lo que demuestra que estas explosiones probablemente son el resultado de la fusión de dos estrellas de neutrones. Operado conjuntamente por grupos de investigación de Dinamarca y la República Checa, este telescopio se puede ver en pleno funcionamiento todas las noches a través de su cámara web.
Este telescopio no estudia exclusivamente estos eventos energéticos, pero BlackGEM, desarrollado en los Países Bajos y Bélgica, fue diseñado específicamente para hacerlo. Cuando los objetos grandes, como las estrellas de neutrones, se fusionan, crean ondas en el tejido del espacio-tiempo, al igual que las ondas de un lago. Tan pronto como se determina la ubicación aproximada de estos eventos con detectores de ondas gravitacionales como LIGO y Virgo, BlackGEM escanea el área para buscar cualquier brillo visible que no estuviera allí antes.
Estos eventos son extremadamente difíciles de rastrear y diferenciar de otros fenómenos en el cielo nocturno. Por esta razón, BlackGEM está utilizando la ayuda de la ciudadanía para detectar explosiones. Puede que sea el momento de transformar tu smartphone en un telescopio “seta” de bolsillo...
