Rodeando a Antu
A pesar de su nombre, el VLT (Very Large Telescope) de ESO, ¡no es un solo telescopio! De hecho, está formado por un conjunto de cuatro Unidades de Telescopio (UTs) de 8,2 metros de diámetro (uno de los cuales se muestra en la imagen) y cuatro Telescopios Auxiliares (ATs) móviles de 1,8 metros de diámetro.
Cada UT tiene nombre propio en el idioma Mapuche (Mapudungun). La estrella de esta imagen es Antu (o UT1, el primero de las UTs) y en la foto aparece en la cima de Cerro Paranal, en Chile. Esta imagen polícroma, tomada por el Fotógrafo Embajador de ESO, Petr Horálek, también capta los bellos colores del cielo nocturno que rodea a Antu.
En esta imagen pueden contemplarse multitud de objetos del cielo nocturno. Empezando por la izquierda, vemos la rosácea nebulosa California, el cúmulo estelar de las Pléyades, el río ardiente de la Vía Láctea, la constelación de Orión y su famoso cinturón, la nebulosa Gum serpenteando, la nebulosa de Carina y la Cruz del Sur. Las características más curiosas son las rayas o bandas verdes a la derecha de la cúpula de Antu. Son ondas de gravedad atmosféricas, generadas por las tormentas que forman ondulaciones en la capa verde de la luminiscencia nocturna de la Tierra, en la atmósfera superior. Esta imagen también apareció en un ESOcast dedicado a los Duendes rojos, un fenómeno que puede ocurrir bajo condiciones similares a las que se dan con las ondas de gravedad.
