Like a tiny snail shell lying on a beach, a small spiral juts out from the expanse of the Atacama Desert. While most of the lines carving the landscape in today's Picture of the Week are natural consequences of geology, the circling path is in fact a road leading up the mountain Cerro Armazones. At the top sits ESO's Extremely Large Telescope (ELT), currently under construction, visible only as a black dot below the centre of this image.
Pinpointing the ELT in the vast area of reds and greys might, at first, make its name seem excessive. But it is all a matter of perspective. This photo was taken by Sophie Adenot, a French engineer, helicopter pilot and astronaut at the European Space Agency (ESA), currently on the International Space Station (ISS) for a long-duration mission called εpsilon. Even from her vantage point, more than 400 kilometres above the Earth's surface, the ELT is a distinguishable feature in the landscape. Once completed, it will be the world's largest visible and infrared light telescope. Its immense light-gathering capability will allow the ELT to probe deeper into the Universe than ever before. An avid stargazer herself, Adenot has sent a log from the ISS to explain why the ELT's location was chosen:
Day 051, orbit 802 – Chile has some of the most beautiful skies on Earth… Stargazing takes on a different dimension there, with three galaxies perfectly visible to the naked eye in the night sky – our very own Milky Way and its two neighbours, the large and small Magellanic Clouds.
The Mars-like Atacama desert is home to several of ESO’s observatories, including at La Silla and Cerro Paranal. This picture shows the construction site of ESO’s Extremely Large Telescope (ELT) on Cerro Armazones. Once completed, the ELT will become the world’s biggest eye on the sky, featuring a 39-meter-diameter mirror… that’s about 9 cars parked bumper-to-bumper, or two H225 helicopters nose-to-tail!
Collaboration between Europe and Chile at its best!
