Primera imagen de un agujero negro
El Telescopio de Horizonte de Sucesos (EHT, Event Horizon Telescope), un conjunto de ocho telescopios basados en tierra distribuidos por todo el planeta y formado gracias a una colaboración internacional, fue diseñado para captar imágenes de un agujero negro. En ruedas de prensa coordinadas por todo el mundo, los investigadores del EHT han revelado que han logrado obtener la primera evidencia visual directa de un agujero negro supermasivo y su sombra.
La sombra de un agujero negro que vemos en la imagen es lo más cerca que podemos estar de una imagen del propio agujero negro, un objeto totalmente oscuro del que la luz no puede escapar. El límite del agujero negro —el horizonte de sucesos del que el EHT toma su nombre— es aproximadamente 2,5 veces más pequeño que la sombra que proyecta y mide casi 40.000 millones de km. Aunque puede parecer grande, este anillo se extiende sólo unos 40 microsegundos de arco, lo que equivaldría a medir la longitud de una tarjeta de crédito sobre la superficie de la Luna.
Aunque los telescopios que forman el EHT no están conectados físicamente, son capaces de sincronizar sus datos con relojes atómicos — máser de hidrógeno — que miden con precisión el tiempo en que se toman las observaciones. Estas observaciones fueron recogidas en una longitud de onda de 1,3 mm durante una campaña mundial desarrollada en 2017. Cada telescopio del EHT produjo enormes cantidades de datos –aproximadamente 350 terabytes por día– que se almacenaron en discos duros de helio de alto rendimiento. Estos datos se enviaron a superordenadores especializados — conocidos como correladores — instalados en el Instituto de Radioastronomía Max Planck y el Observatorio Haystack del MIT, donde se combinaron. Luego, cuidadosamente, se convirtieron en una imagen utilizando novedosas herramientas computacionales desarrolladas por la colaboración.
