Bok Prize

Professor Bart Jan Bok was Director of Mount Stromlo Observatory from 1957 to 1966. He energetically promoted the undergraduate and graduate study of astronomy in Australia and set up the Graduate School of Astronomy at the Australian National University.

Bart shared a successful scientific collaboration with his wife, Dr Priscilla Bok. Together they also published the highly popular astronomy book The Milky Way. As a talented populariser of astronomy, Bart is particularly remembered for his entertaining broadcasts on ABC radio.

The Bok Prize is awarded annually by the Astronomical Society of Australia to recognise outstanding research in astronomy or a closely related field, by an Honours student or eligible Masters student at an Australian university.

The prize consists of the Bok Medal together with an award of $1,000 and ASA membership for the following calendar year. The recipient is invited to present a paper on their research at the Annual Scientific Meeting of the Astronomical Society of Australia, where the prize will be presented.

Nominations for the 2025 Bok Prize will open in December 2024 with a closing date of mid-February 2025.


To be eligible for the Prize, the nominee:

  • must have been an Honours student or eligible Masters student* at an Australian university in the previous calender year (ie. at 30 June in the year prior to the award).
  • must have completed their degree requirements in the previous calendar year.
  • must have been carried out research in an area of astronomy or closely related field.

* Eligible Masters students are those who have entered their Masters degree from a 3 year undergraduate degree. Students who completed an Honours year before entering the Masters degree are not eligible for the Bok prize.


Nominations must adhere to the following guidelines:

  • each Australian university can submit a maximum of two nominations per year (unless a special case can be made for an additional nomination).
  • nominations must be endorsed by the Head of the nominee’s academic unit, in consultation with their academic staff. The Head should also certify that the applicant’s degree requirements have been completed during the previous calendar year.
  • nominations must be submitted by the candidate’s supervisor.
  • the nomination must include an electronic copy of the Honours/Masters thesis.
  • the nomination must include a brief statement (~1/2 page) by the nominee, clearly describing their major contributions to the research, the resources they used and the help they received. This may already be included as part of the thesis.
  • the nomination must also include a completed Supervisor’s Statement – this is a confidential statement by the nominee’s supervisor detailing the highlights of the research, indicating the relationship of the submission to the student’s course requirements, and highlighting the originality of the work. Please use the Supervisor’s Statement form (Word or pdf).

Nominations should be emailed to the ASA Prizes and Awards Coordinator, Dr Tanya Hill –

An assessment committee nominated by the ASA Council will evaluate the submitted materials and make a recommendation to the ASA Council. The decision of the ASA Council is final, including a decision not to award the prize in any given year.

Limited travel funds to support attendance at the ASA Annual Scientific Meeting may be made available at the discretion of the ASA Council.
