Cuando las luces colisionan

This Picture of the Week captures the skies above ESO’s Paranal Observatory ablaze with colour — blues, purples, oranges, greens, yellows and reds all mingle together to create this striking view of the Chilean site. One of the Auxiliary Telescopes (ATs) comprising ESO’s Very Large Telescope (VLT) is visible in the foreground, bathed in an eerie yellow-green glow.  This AT is just one of the VLT’s four 1.8-metre auxiliaries, which also includes four giant 8.2-metre cousins (Unit Telescopes).The ATs are unique; they are self-contained and, depending on the needs of the observing project, can be repositioned in up to 30 different observing locations along a system of tracks. Acting together as the VLT Interferometer (VLTI), they capture light from celestial objects and send it to the same focal point through a system of mirrors housed within underground tunnels, allowing researchers to observe the cosmos in incredible detail.  Comprising eight telescopes in total, the VLT is the world’s most advanced visible-light astronomical observatory. Its magnificent resolution makes it possible to see fine detail on the surface of a star, and even to study the surroundings of a black hole.

Esta imagen de la semana capta los cielos del Observatorio Paranal de ESO ardiendo en colores: azules, púrpuras, naranjas, verdes, amarillos y rojos se mezclan para crear esta impresionante vista de la ubicación chilena. En primer plano puede verse uno de los telescopios auxiliares (AT) que comprende el Very Large Telescope (VLT) de ESO, bañado en un misterioso resplandor amarillo-verdoso.

Este AT es sólo uno de los cuatro telescopios auxiliares de 1,8 metros del VLT, que también incluye cuatro primos gigantes de 8,2 metros (Unidades de Telescopio). Los AT son únicos; son autónomos y, dependiendo de las necesidades del proyecto de observación, pueden ser recolocados en hasta 30 lugares de observación diferentes a lo largo de un sistema de pistas. Actuando juntos como el Interferómetro VLT (VLTI), captan la luz de los objetos celestes y la envían al mismo punto focal a través de un sistema de espejos alojados dentro de túneles subterráneos, permitiendo a los investigadores observar el cosmos con un increíble nivel de detalle.

Compuesto por ocho telescopios en total, el VLT es el observatorio astronómico de luz visible más avanzado del mundo. Su magnífica resolución permite ver detalles finos en la superficie de una estrella, e incluso estudiar el entorno de un agujero negro.
