Celebrando el nacimiento de nuevas estrellas... ¡y del VST!
Imagine por un momento que está mirando hacia el cielo, observando las nubes de un color rojo-anaranjado que vemos en la Imagen de la Semana de hoy. ¿Qué formas puede ver? ¿Una gallina picoteando semillas en el suelo, la cabeza de un dragón o algo completamente distinto?
Estas nubes que inducen a la pareidolia son un par de nebulosas — colecciones de polvo y gas en el espacio interestelar — llamadas Gum 10 y Gum 11. Visibles principalmente desde el hemisferio sur, forman parte de un complejo mayor en el que están naciendo estrellas. Gum 10 es la nube más brillante que ocupa la mayor parte de la imagen, mientras que Gum 11 es la nube más tenue y separada que vemos en la parte inferior izquierda. Su brillante resplandor proviene de una interacción especial entre el hidrógeno y las estrellas masivas y calientes de cada nebulosa. Estas estrellas emiten luz ultravioleta, que tiene suficiente energía como para arrancar electrones de sus átomos, formando iones. Estos electrones finalmente se recombinan con iones de hidrógeno, lo que provoca la emisión del tono específico de luz roja que se ve en esta imagen. Las líneas negras de la nebulosa provienen del polvo que bloquea la luz que hay detrás.
Esta imagen fue tomada con el VST (VLT Survey Telescope) que hoy celebra el 15º aniversario de su primera luz. El proyecto VST fue una empresa conjunta entre ESO y el Observatorio Astronómico de Capodimonte (OAC), parte del Instituto Nacional Italiano de Astrofísica (INAF). Hoy en día, el VST está gestionado exclusivamente por el INAF y está alojado en el Observatorio Paranal de ESO, en Chile. Los datos tras esta imagen provienen de un proyecto llamado VPHAS+, que utiliza el VST para escanear el plano de nuestra galaxia Vía Láctea, destinado a comprender mejor el ciclo de vida de las estrellas.
