Image Astro du jour
At ESO’s Paranal Observatory in Chile, sunset does not mark the end of the day. Instead, it signals the beginning of a night under the stars. Today’s Picture of the Week comes from the Residencia, a home away from home for astronomers and other staff members working in shifts at the remote Atacama Desert site. In this photo, the last rays of sunlight slice through one of the Residencia’s corridors, casting lines of light and shadow across the concrete interior. At the far end of the ramp, a solitary figure stands in the light, framed between day and night.
ESO staff astronomer and photographer Luca Sbordone spotted this scene as he returned from dinner before heading to the telescopes for a night of observing. Knowing that the angle of the shadows would only last a few minutes, he ran to fetch his camera and recruited a colleague to add a human element to the image.
The Residencia is the part-time home for the people who keep Paranal running. Built partly below ground and designed to blend into the Atacama Desert, it offers shelter from one of the driest environments on Earth. Natural daylight reaches its central spaces through a 35-metre-wide dome and several skylights. Each day as daylight fades, a night of observations begins.
