I am delighted to address the Gemini community from my new role as the Observatory’s Interim Director. I will hold this position for the next year, while the search for a perma- nent Director moves forward. As I write this (beginning of September), I have been in Hilo, Hawai‘i, for almost two months, and it’s been an exciting time. I have enjoyed work- ing with the Gemini staff, whose drive, dedication, and talent were already well known to me from when I chaired the Observatory Oversight Council on behalf of the Association of Universities for Research in Astronomy (AURA). -

50 Years of Existence of the European Southern Observatory (ESO) 30 Years of Swiss Membership with the ESO
Federal Department for Economic Affairs, Education and Research EAER State Secretariat for Education, Research and Innovation SERI 50 years of existence of the European Southern Observatory (ESO) 30 years of Swiss membership with the ESO The European Southern Observatory (ESO) was founded in Paris on 5 October 1962. Exactly half a century later, on 5 October 2012, Switzerland organised a com- memoration ceremony at the University of Bern to mark ESO’s 50 years of existence and 30 years of Swiss membership with the ESO. This article provides a brief summary of the history and milestones of Swiss member- ship with the ESO as well as an overview of the most important achievements and challenges. Switzerland’s route to ESO membership Nearly twenty years after the ESO was founded, the time was ripe for Switzerland to apply for membership with the ESO. The driving forces on the academic side included the Universi- ty of Geneva and the University of Basel, which wanted to gain access to the most advanced astronomical research available. In 1980, the Federal Council submitted its Dispatch on Swiss membership with the ESO to the Federal Assembly. In 1981, the Federal Assembly adopted a federal decree endorsing Swiss membership with the ESO. In 1982, the Swiss Confederation filed the official documents for ESO membership in Paris. In 1982, Switzerland paid the initial membership fee and, in 1983, the first year’s member- ship contributions. High points of Swiss participation In 1987, the Federal Council issued a federal decree on Swiss participation in the ESO’s Very Large Telescope (VLT) to be built at the Paranal Observatory in the Chilean Atacama Desert. -

La Silla Paranal Observatory Observatory

The unit was installed on top of the HARPS adaptor flange. The current precision in the measurement of the radial velocity of stars down to 60 cm/sec in the long term, has permitted to discover the majority of the “super Earth” type of extra solar planets up to date. Several factors enter in the radial velocity error budget, among these is the guiding accuracy, which has direct influence on the light injection into the spectrograph’s fiber. Guiding is actually done by corrections directly sent to the telescope with frequencies in the range of 0.2 Hz-0.05 Hz, depending on the brightness of the target. Due to mechanical limitations of the telescope there is an expected relaxation time of approximately 2 sec. The final objective of this modification is to reach radial velocities precision of 30 cm/sec with HARPS, that will allow the detection of Earth mass planets in close-in orbits.

Esocast Episode 29: Running a Desert Town 00:00 [Visuals Start
ESOcast Episode 29: Running a Desert Town 00:00 [Visuals start] Images: [Narrator] 1. The Atacama Desert in northern Chile — one of the driest and most hostile environments in the Plain desert world. Under the blazing Sun, only a few species of animals and plants have evolved to survive. Yet, this is where the European Southern Observatory operates its Very Large Telescope. Running this technological oasis in the barren desert, Paranal seen from distance and making it a comfortable place for people to live, poses many challenges. 00:42 ESOcast intro 2. This is the ESOcast! Cutting-edge science and life ESOcast introduction behind the scenes of ESO, the European Southern Observatory. Exploring the ultimate frontier with our host Dr J, a.k.a. Dr Joe Liske. 00:59 [Dr J] Dr J in studio, on screen: 3. Hello and welcome to the ESOcast. Paranal observatory Cerro Paranal, in the heart of the Atacama Desert, is one of the world’s best sites for observing the night sky. Paranal observatory But operating an observatory with more than 100 staff in such a remote and isolated place poses a real logistical challenge; it’s like running a desert town. 1:25 [Narrator] 4. Everything that is needed to make this Mars-like Water truck landscape a haven for people has to be brought in from far away. The most essential delivery to the arid desert is water. The observatory needs up to 70 000 litres of water each day, and literally every drop has to be brought in from the town of Antofagasta, which lies about 120 kilometres away. -
