Message from the Director General

Published: 22 Dec 2020

The year 2020 will go into history as an exceptional one in almost every area of human activity. While we are still suffering the direct impact of the global pandemic and these will surely continue for some time, the end of the year is a suitable occasion to sincerely thank the efforts of our scientific community to carry on producing excellent science. I also wish to express my appreciation to all ESO staff and to our partners and contractors in the Member States and Chile for finding creative ways of enabling our projects to move forward, and of resuming astronomical observations and the delivery of scientific data. Last but not least, my warmest thanks to the Member State delegations in our governing bodies for their continued, unfailing and invaluable support to ESO.
