Summary
[edit]DescriptionSunset Skies at CTIO (iotw2053a).tiff |
English: The mountains of northern Chile fade into the distance under a vibrant orange sky in this sunset photograph of Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. More than 20 telescopes operate at CTIO — and many of them can be seen jutting from the mountain in the foreground of this image. The Víctor M. Blanco 4-m Telescope and the SMARTS Telescopes dominate the mountain peak, with smaller telescopes spread along the ridge. Despite the tranquility of the sunset, the engineers and astronomers at the observatory are working hard, spending the hours before dusk preparing a packed schedule of scientific observations. |
