Mechanical Engineer Emanuela Ciattaglia Works on Extremely Large Telescope

Mechanical Engineer Emanuela Ciattaglia Works on Extremely Large Telescope

In this video, we meet the European Southern Observatory's Emanuela Ciattaglia, a native of Italy. She is a mechanical engineer currently working on ESO’s Extremely Large Telescope (ELT) in Chile. From our headquarters in Garching, Germany, she coordinates activities for the assembly, integration and verification phase of the ELT.

This is the first of a new series of videos, featuring people at ESO working in a range of roles across departments and topics.

This soon-to-be telescope is located at the top of Cerro Armazones. At 3046 meters above sea level, and with very dry conditions, the ELT is in the perfect location for astronomical observations under one of the most pristine skies on Earth. Its dome, planned to be fully completed in 2027, protects the telescope and its sensitive components from the extreme desert environment, and from the Sun during daytime. At night, its two massive sliding doors will open to allow the telescope to observe the night sky, while still protecting it from the wind.

Inside the dome, the construction of the main structure of what will be the world's largest optical and near-infrared telescope is very advanced. With the first light planned for the end of the decade, the ELT and its groundbreaking 39-meter main mirror will take on some of the biggest challenges in astronomy and, ultimately, help us understand our place in the Universe.
