Image Astro du jour
A circular hole creates a perfect frame for today's Picture of the Week, taken during sunset at ESO's Paranal Observatory in Chile. The opening — which resembles the aperture of a camera, or the pupil of an eye — abstracts the site into shapes. "I can't help noticing that spheres and circles are everywhere in astronomical architecture," reflects the photographer, ESO astronomer Luca Sbordone. The two visible round cutouts, and spherical dome in the distance, resonate with the planets, moons, and stars we find when we look deep into the cosmos.
The circles are found around the bases of the enclosures for each of the four Unit Telescopes (UTs) that make up ESO's Very Large Telescope (VLT). The cutouts are part of structural supports for the observing floor of the 8.2 metre telescopes. While the openings helped to create this stunning composition, they also serve a practical purpose. They reduce the amount of concrete required in constructing supports, as well as providing better airflow and thermal inertia around the telescopes — minimising any adverse effects that could distort observations.
This image was taken below the UT3 telescope and, to the right, the edge of the UT2 telescope is visible. In the distance is an Auxiliary Telescope (AT), one of four moveable telescopes that feeds light into the VLT Interferometer. Half illuminated by the setting Sun, the AT's round enclosure looks like a quarter Moon.
