El Observatorio Europeo Austral (ESO) ha publicado una imagen de ochenta millones de p\u00edxeles del c\u00famulo estelar RCW 38, captada por el telescopio VISTA, que opera en el desierto de Atacama, en Chile. La imagen, obtenida en luz infrarroja, muestra con gran detalle una regi\u00f3n de formaci\u00f3n estelar situada a unos 5500 a\u00f1os luz de la Tierra, en la constelaci\u00f3n de Vela.<\/p>\n

RCW 38 es un c\u00famulo joven, con menos de un mill\u00f3n de a\u00f1os de antig\u00fcedad, que alberga unas 2000 estrellas. A diferencia del Sol, que con sus 4600 millones de a\u00f1os ha alcanzado una fase estable, las estrellas de RCW 38 est\u00e1n en pleno proceso de evoluci\u00f3n. La intensa radiaci\u00f3n que emiten hace que el gas circundante brille en tonos rosados, un fen\u00f3meno caracter\u00edstico de las regiones de formaci\u00f3n estelar.<\/p>\n

Muchas de estas estrellas permanecen ocultas en luz visible debido a la presencia de densas nubes de polvo. Sin embargo, el telescopio VISTA, equipado con una c\u00e1mara de infrarrojos, permite atravesar este velo y revelar estructuras que de otro modo ser\u00edan invisibles. En la imagen, adem\u00e1s de estrellas j\u00f3venes envueltas en polvo, se pueden distinguir enanas marrones, objetos estelares que no lograron acumular suficiente masa para iniciar la\u00a0fusi\u00f3n nuclear.<\/p>\n

Formaci\u00f3n estelar y la evoluci\u00f3n de c\u00famulos<\/h2>\n

La imagen forma parte del sondeo VVV (VISTA Variables en la V\u00eda L\u00e1ctea), que ha permitido obtener el mapa infrarrojo m\u00e1s detallado de nuestra galaxia hasta la fecha. Este tipo de estudios contribuyen a comprender mejor los procesos de formaci\u00f3n estelar y la evoluci\u00f3n de los c\u00famulos.<\/p>\n

Desde la captura de esta imagen, la c\u00e1mara VIRCAM de VISTA, en operaci\u00f3n desde 2008, ha sido retirada tras m\u00e1s de una d\u00e9cada de servicio. A finales de este a\u00f1o, el telescopio ser\u00e1 equipado con un nuevo instrumento, 4MOST, dise\u00f1ado para analizar de forma simult\u00e1nea el espectro de 2400 objetos en un \u00e1rea extensa del cielo. Con esta actualizaci\u00f3n, VISTA continuar\u00e1 proporcionando datos clave para la astronom\u00eda en los pr\u00f3ximos a\u00f1os.<\/p>","protected":false},"excerpt":{"rendered":"
