(They were open from 30 November 2023 to 01 March 2024 and we received over 3000 submissions!)

There will still be UNCONFERENCE sessions:

The IAU General Assembly will include “unconference sessions” which will allow for talks to be proposed and voted upon at the event itself. Practically it would mean that anyone attending the IAU GA (in person or online) will be able to propose a talk, workshop or discussion session and all the other attendees will have an opportunity to vote for their favourites. The proposals with the highest votes will be given a space in the venue to present their talk/workshop/discussion session. This means that any gaps in topics can be proposed, as well as new scientific developments that may have taken place since the submission of abstracts closed. Unconference sessions are an excellent way for participants to take to a stage and present any work/topic that is new and/or of interest to the other participants.

The text below is for information only. If you wish to submit a late abstract or make any changes you may contact the chairs of the respective SOCs to obtain their permission. The organisers will be as flexible as possible about logistics but the scientific decisions rest with the respective SOCs.

  • Abstracts are invited for
    • Oral Presentations (in-person or online)
    • Posters (in-person or online)
    • Further information such as modalities for online and in-person presentation and specifications for posters will be shared later
  • Submit your abstracts at the link below. You will receive an automated email confirmation when you successfully submit an abstract. Please note that submitting the abstract without completing all required fields will SAVE the application but NOT submit.
  • Saved and Submitted abstracts will be visible on your dashboard and can be amended until the deadline of 01 March 2024.
  • Refer to the Programme for detailed information on the various scientific sessions and meetings.
  • Abstracts may be submitted without registering for the meeting. However, registration is required by 01 March 2024 if you are also submitting a grant application (note that this is also the deadline for early bird rates).

For detailed instructions, see our step-by-step guide on submitting abstracts/grants. For any queries, email us at registrations@astronomy2024.org.

Deadline for abstracts: 01 March 2024 

The exact time of the deadlines indicated is midnight UTC-12 (in other words, there should be nowhere in the world where it is still that date)

Guidelines for IAU Grants

  • IAU Grants are expected to be attributed to qualified participants to whom only limited means of support is available, e.g., colleagues from economically less privileged countries and young scientists.
  • IAU Grants are expected to be the seed money in ensuring the participation of a selected beneficiary, rather than adding comfort for colleagues whose attendance is already assured.

Eligibility for IAU Grants

  • Eligible participants for the IAU Grants need to submit (at least) one abstract to be presented at the General Assembly.
  • IAU membership is not required.
  • Grants are given only to participants with accepted abstracts.
  • All applicants should register for the conference before the grant application deadline and select the “Offline Payment” option (no payment is required until the outcomes of the grants are known). In this way even unsuccessful grant applicants will still receive the lower early bird rate.

Selection for IAU Grants

  • The SOCs grade the application for its scientific merit. If a participant submits multiple abstracts, they will all be considered.
  • The IAU General Secretary allocates grants based on the overall funding available, the above criteria, and the input of the SOCs. The General Secretary informs the IAU Executive Committee of their decision.
  • The final allocation is expected to show a reasonable distribution of gender and country of work.

*If you are in a country affected by conflict, international sanctions or any other situation preventing your physical participation in the IAU General Assembly, please contact the IAU secretariat (link) to discuss virtual participation fee waivers.


The African Astronomical Society (AfAS) and the National Organizing Committee of the IAU General Assembly 2024  (IAU-GA2024) invite Africa-based astronomers and students to apply for grants to attend this landmark event, as it marks the first time the assembly will be held on the African continent. These grants are an effort to promote the participation of Africa-based astronomers and students in this significant international conference, to foster participation, inclusion and growth in the field of astronomy within Africa. They are intended as seed funding to ensure participation rather than adding comfort for those whose attendance is already secured. The funding for these grants comes primarily from the South African Department of Science and Innovation, with additional support from the LSST Discovery Alliance (LSST-DA). An independent review panel will be appointed by AfAS, in consultation with the funders, to assess grant applications based on the eligibility and selection criteria..

Eligibility for Africa Grants:

  1. Residence and Institutional Affiliation: Applicants should reside, and be affiliated with an institution based on the African Continent.
  2. Abstract Submission and grant application: Applicants must submit one or more abstracts for the conference, and must complete the grant application questions, which are available during abstract submission.
  3. Membership: Membership of professional bodies such as AfAS or IAU is not required.
  4. Conference Registration: Applicants should register for the IAU-GA2024 before the grant application deadline, selecting the “Offline Payment” option (no payment is required until the outcomes of the grants are known). This also ensures that even unsuccessful applicants benefit from the early bird rate.

Selection for Africa Grants: 

  1. Quality of Abstract: Preference will be given to participants with high quality abstracts that are relevant to the IAU-GA2024.
  2. Means of Support: Priority will be given to applicants with limited means of support or those based in (African) countries that are on the United Nations list of least developed countries.
  3. Inclusion: Selection will take into account gender and geographical distribution among recipients.


We list some of the other grants offered by entities besides the IAU and the National Organizing Committee. Please visit the relevant websites below for further information.

For individuals seeking funding we advise contacting your institution who may be able to offer support in searching for funding opportunities. Please also check with your national research funding body if they will fund conference attendance. Finally, grant alert portals such as Funds4NGOs may also provide useful information on potential funders.

Australian High Commission on South African Direct Aid Program

Dear Astronomers,

We are delighted to invite applications from researchers across Africa for an exclusive hands-on workshop on the James Webb Space Telescope (JWST), to be held in conjunction with the International Astronomical Union General Assembly (IAU GA) in Cape Town.

This workshop offers a unique opportunity for researchers to gain practical experience with JWST data and tools. Participants will first attend the IAUS#391 symposium between 6-9th August, ensuring a comprehensive understanding of the latest developments and research in cosmic history through JWST. The hands training will take place on the 9th of August. In addition to the workshop and symposium, a networking event will be organised, allowing participants to meet and engage with international researchers working with JWST. This will be an excellent opportunity to build connections, exchange ideas, and foster collaborations within the global astronomy community.

Limited travel grants are available to support select participants supported by Australian High Commission on South African Direct Aid Program.

To apply, please fill up the short form here https://forms.office.com/r/95A2svb6gi by the 7th of June 2024.

We look forward to your participation in this exciting event and to advancing our collective understanding of the cosmos through the unparalleled capabilities of JWST.

For any questions please contact: Dr. Themiya Nanayakkara (wnanayakkara@swin.edu.au)
