ESO Fellowship Programme Europe 2022/ 2023


Vacancy closed on 15/10/2022

Deadline 15/10/2022

The European Southern Observatory (ESO) invites applications for the ESO Fellowship Programme 2022/2023. The Programme is designed to help early career scientists to develop their independent research programmes and successfully reach the next step of their scientific careers by:

  • Developing their scientific profiles benefiting from a rich and structured scientific environment where they can interact with more senior scientists;
  • Becoming mature and independent researchers who will develop their own research projects and contribute effectively to collaborative scientific endeavours;
  • Getting prepared to take on higher scientific, technical or supervisory/managerial responsibilities in future positions.

Fellowships are available both at ESO's Headquarters in Garching near Munich, Germany, and at ESO's astronomy centre in Santiago, Chile. ESO Fellows are expected to actively participate in ESO's scientific life by proposing and getting involved in the organisation of scientific workshops, co-supervising PhD students, coordinating thematic research groups, joining scientific committees, organising seminars, writing competitive grant and telescope proposals, etc.

For more information about the fellowship programme and ESO's astronomical research activities, please see

The ESO Fellowship Programme: ESO-Germany

The ESO Headquarters is situated in one of the most active research centres in Europe, next to the campus of the Technical University of Munich (TUM), boasting one of the highest concentrations of astronomers. High-calibre scientists, instrument experts, and other professionals are all within easy reach, providing fellows with valuable opportunities to start collaborations and learn new skills. ESO's offices are adjacent to the Max Planck Institutes for Astrophysics and for Extra-terrestrial Physics and close to the observatory of Munich's Ludwig-Maximilian University. On the Garching campus, ESO also participates in the ORIGINS Cluster, which gathers nearly 200 scientists, and the IMPRS Programme for PhD students. For a list of current ESO staff and fellows, and their research interests please see The ESO Fellowship positions in Garching are 3 years in duration. In addition to developing their independent research programmes, ESO Garching Fellows are expected to engage in functional work for 25% of their time. During this fraction of time, Fellows are trained in crucial areas of high-level technology and/or actively participate and contribute to ESO projects which they select from activities proposed by different departments. Details on the nature of the projects can be found here

The ESO Fellowship Programme: ESO-Chile

The ESO Vitacura Office, in Santiago, is where ESO Fellows have the possibility to interact with Instrument and System Scientists, and Science Operations Managers from Paranal, ALMA, La Silla, and APEX Observatories. There is also a continuous flow of visiting astronomers and observers that allows stimulating scientific interactions with the international community. ESO Chile is an excellent place to increase collaborations with the Chilean astronomical community and with astronomers at other international observatories located in the country. The Joint ALMA Observatory is also located on ESO's Vitacura campus, further enhancing the scientific environment available to ESO Chile Fellows. For a list of current ESO astronomers and their research interests, please see: ESO Fellowships in Chile are granted for 4 years. During the first three years, the Fellows are assigned to one of the Science Operation groups of Paranal or ALMA, where they contribute at a level of 80 nights per year, corresponding to 50% of their working time. Fellows with duties at ALMA will have opportunities to participate in ALMA operations, including observing at the telescope, data processing, software testing, serving as technical experts in the ALMA proposal review process, and developing new capabilities for the array. At Paranal, Fellows act as support astronomers, doing service-mode observations or helping visiting astronomers to achieve their scientific goals. They are also expected to join an Instrument Operations Team. In the role of Instrument Fellow, they gain an in-depth knowledge of various aspects of a given instrument such as engineering and technological characteristics, specific operational aspects, and data reduction. In these environments, ESO Chile Fellows have the opportunity to develop useful skills in project management, team coordination, and communication in a multi-disciplinary environment. Exploiting this unique mix of technical knowledge and their close contact with the science carried out at the Observatories, ESO Chile Fellows can build a solid research programme that can boost their future career. The work of a fellow involves duties and responsibilities at the Observatory. The ideal candidate is able to demonstrate comprehension of general science cases outside the candidate's field of research, has good communication skills, is able to work independently, has time management skills, and is able to take personal responsibility.

ESO Chile Fellows may choose to spend the fourth year either at ESO's astronomy centre in Santiago, at ESO Headquarters in Garching, at any astronomy/astrophysics institute in an ESO member state or in ESO's strategic partner, Australia. There are no functional duties during the fourth year except in the case that the fourth year is spent at ESO Chile, where Fellows are expected to carry out functional work for up to 25% of their time. Under certain conditions, the Fellow may also be hosted by a Chilean institution where they will be eligible to apply for time on all telescopes in Chile through competition for Chilean observing time.


The programme is open to applicants who will have achieved their PhD in astronomy, physics or a related discipline before 1 November 2023. Early-career scientists from all astrophysical fields are welcome to apply. Observational, theoretical and computational astrophysics are all areas where ESO Fellows can benefit from one of the most vibrant and stimulating scientific settings anywhere in the world.

Remuneration and Contract

We offer an attractive remuneration package including a competitive salary and allowances, comprehensive social benefits, and we provide financial support for relocating families.
