2023 Users Committee Meeting and Poll

Published: 13 Mar 2023

The Users Committee (UC) represents ESO's astronomical community at large and acts as an advisory body to the ESO Director General on matters related to the performance, scientific access, operation and user interfaces to the La Silla Paranal Observatory and ALMA. The annual meeting of the UC is scheduled on 20 and 21 April 2023. During the UC meeting updates from ESO and feedback from the user community are exchanged and openly discussed. Each year one topic is explored in more detail and this year the Special Topic session is dedicated to Archive Science.

Applications for ESO Studentships - First Annual Call

Published: 09 Mar 2023

The ESO research studentship programme provides an outstanding opportunity for PhD students to experience the exciting scientific environment at one of the world's leading observatories. ESO's studentship positions are open to students enrolled in a university PhD programme in astronomy or related fields. Students accepted into the programme work on their doctoral project under the formal supervision of their home university supervisor, but they come to ESO to work and study under the co-supervision of an ESO staff astronomer for a period of between six months and two years.
