| Description |
English: Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab, is depicted here with the Milky Way and several nebulae within it, including the Lagoon Nebula and Rho Ophiuchi cloud complex. A number of CTIO telescopes are captured in this 360-degree panorama, including, from left to right: the UBC Southern Observatory, the SMARTS 1.0-meter Telescope, the Curtis Schmidt Telescope, the Víctor M. Blanco 4-meter Telescope, the SMARTS 1.5-meter Telescope and the SMARTS 0.9-meter Telescope. Various other, more unusual night sky phenomena are also visible. The white glow on the left of the image is zodiacal light, arising from interplanetary dust illuminated by the Sun. The green, orange, and reddish “clouds” near the horizon are airglow, caused by trace gasses in the upper atmosphere.
Español: El Observatorio Cerro Tololo (CTIO), un Programa de NOIRLab de NSF y AURA, se muestra aquí con la Vía Láctea y muchas nebulosas dentro de ella, incluyendo la Nebulosa de la Laguna y el complejo de formación estelar Rho Ophiuchi. En esta panorámica de 360 grados aparecen varios telescopios de CTIO, incluyendo, de izquierda a derecha: el UBC Southern Observatory, el Telescopio SMARTS de 1 metro, el Telescopio Curtis Schmidt, el Telescopio de 4 metros Víctor M. Blanco, el Telescopio SMARTS de 1,5 metros y el Telescopio SMARTS de 0,9 metros.
En la fotografía también podemos ver otros fenómenos más inusuales en el cielo nocturno: El resplandor blanco a la izquierda de la imagen es la luz zodiacal que se genera por el reflejo del Sol sobre el polvo interplanetario. Las “nubes” verdes, anaranjadas y rojizas cerca del horizonte son ejemplos del fenómeno conocido como luminiscencia nocturna o airglow, causado por los gases presentes en la atmósfera superior. |
