The European Southern Observatory (ESO) offers an exceptional opportunity for PhD students to conduct research in a dynamic and scientifically rich environment. Our Studentship Programme allows students to work at one of the world's leading observatories for a period of one to two years.

As the premier intergovernmental astronomy organisation in Europe, ESO boasts a vibrant community of approximately 110 staff astronomers, 40 fellows, and 40 PhD students. Our researchers are at the forefront of discoveries across a wide range of fields, from exoplanets to cosmology, making ESO one of the most collaborative and stimulating scientific environments globally.

Eligibility and Supervision:

• The ESO Studentship positions are open to students enrolled in a PhD programme in astronomy or related scientific fields, including observational, theoretical, and fundamental astrophysics.
• Students will work on their Studentship project under the formal supervision of their home university supervisor, while being co-supervised by an ESO staff astronomer, or by a team comprising an ESO staff astronomer and a fellow.
• Studentship positions in Garching (Germany) are hosted at ESO's Headquarters.

Application Process:

• Applicants should coordinate their research project with their prospective ESO supervisor and their home institute supervisor. Applications can be made for a minimum of one year and up to two years.
• Applicants are strongly encouraged to contact their prospective ESO supervisor well before the application deadlines (the next deadline is 20 April 2026). A list of potential ESO supervisors and their research interests can be found at the end of the announcement.
• Thesis writing is expected to take place at the home institute after the Studentship, although exceptions may be granted if well justified.

Benefits of the Programme:

• ESO students benefit from a collaborative, international, and multidisciplinary environment that encourages innovation and creativity.
• Students are involved in the latest scientific developments and have opportunities to network with top researchers.
• ESO students can also engage in co-organising regular science events such as Journal Clubs, topical coffees, and seminars. Additionally, they may participate in conferences hosted at ESO and mentor master's students in collaboration with ESO fellows or staff astronomers.
• University PhD supervisors of the candidates are encouraged to apply for the ESO Visitor Program (https://www.eso.org/sci/activities/garching/personnelvisitors.html) to support their scientific visit during the Studentship period.

Opportunities for Learning and Outreach:

• Students in Garching can attend lectures through the International Max-Planck Research School on Astrophysics.
• ESO students also have the opportunity to participate in a variety of outreach activities.
