Hey, wake up! It’s already 6am and the taxi will arrive in 15 minutes to take you to the airport. You checked in as early as possible to ensure a seat by the window on the right side of the plane. The views during the flight between Santiago de Chile and the city of Calama, parallel to the Chilean Andes for two hours, are majestic. Ahead you of are 8 days of intensive work at ALMA, arguably the most important ground-based astronomical observatory in the world, given that it is an international effort of peaceful cooperation among more than 20 nations to understand our place in the cosmos. ALMA is formed by 66 antennas that can observe any object in the sky simultaneously to obtain data of unprecedented quality. Such an amazing machine is placed in an amazing location: the Chajnantor plateau, at 5000m above sea level in the middle of the Atacama desert, the driest non-polar place in the planet.
