Construction work on EVALSO

EVALSO (Enabling Virtual Access to Latin American Southern Observatories) is a new communications infrastructure supporting ESO’s Paranal Observatory. The construction of the main 100km long data cable (pictured) took place in the harsh conditions of the Atacama Desert. This new link gives ESO’s Paranal Observatory, and Ruhr-Universität Bochum’s Cerro Armazones Observatory a high-capacity connection to send observational data back to Europe.
