South Africa has made history as the first African nation to host the International Astronomy Union’s General Assembly, the largest global meeting of astronomers.
The two-week event began on 6 August 2024 in Cape Town, bringing together thousands of scientists, educators, and space industry leaders both in person and online. Organizers say the gathering will spotlight Africa’s growing role in astronomy and strengthen international scientific partnerships.
The assembly was officially opened by Science, Technology, and Innovation Minister Professor Blade Nzimande, who addressed delegates from around the world. Keynote speakers include trailblazing astronauts Dr. Mae Jemison, the first African-American woman in space, and Dr. Sian Proctor, who became the first Black woman to pilot a spacecraft. Both will share insights on diversity, innovation, and humanity’s future in space.
The International Astronomy Union (IAU) General Assembly is held every three years and is coordinated for 2024 by the African Astronomical Society. This year’s program features over 2,000 presentations across more than 300 sessions, with topics ranging from planetary science to radio astronomy.
Six symposia, 12 multi-session focus meetings, poster presentations, and award lectures will showcase the latest discoveries and advancements in the field.
According to the Department of Science and Innovation (DSI), one of the most anticipated moments will allow attendees to speak live with astronauts aboard the International Space Station using amateur radio. This collaboration is part of the Amateur Radio on the International Space Station (ARISS) program, which promotes direct public engagement with space missions.
The event is expected to boost public interest in astronomy across Africa, with organizers highlighting the continent’s heritage in stargazing and its rapidly advancing space science infrastructure.
The exhibition hall includes participation from the South African Radio Astronomy Observatory (SARAO), the South African Astronomical Observatory, NASA, the European Space Agency, the National Astronomical Observatory of Japan, the US National Radio Astronomy Observatory, and several South African agencies.
The 2024 assembly aims to strengthen collaborations between African and international institutions, paving the way for future research projects and technology development. Officials say hosting the world’s largest astronomy gathering is not only a milestone for South Africa but also a step forward for the global scientific community.
According to recent reports from SA News, the 32nd General Assembly will also highlight public engagement initiatives and outreach programs designed to inspire the next generation of scientists across Africa.
