The High Commissioner of India to South Africa, Prabhat Kumar, formally handed over the official banner of the Inter-University Centre for Astronomy and Astrophysics (IUCAA) to the South African Astronomical Observatory (SAAO) in Cape Town. The banner will be permanently displayed at the Southern African Large Telescope (SALT) facility, serving as a powerful symbol of the long-standing scientific partnership between India and South Africa. This ceremony reinforces the commitment of both nations to collaborative research in the fields of astronomy and astrophysics within the BRICS framework.
Symbolic Banner Handover at Cape Town
The ceremony, held at the SAAO headquarters, marked a milestone in the decade-long partnership between Indian and South African astronomical institutions. High Commissioner Prabhat Kumar emphasized that the placement of the IUCAA banner at the SALT facility is not merely symbolic but represents the Government of India’s dedication to global scientific innovation. The SALT facility, located in Sutherland, is a premier site for deep-space observation, and the permanent display of the Indian institution’s banner acknowledges India’s status as a key stakeholder in the project.
This gesture also highlights the growing synergy between the two nations in sharing high-tech infrastructure and academic resources. The SAAO, which was founded in 1820 and serves as South Africa’s national center for optical and infrared astronomy, provides the operational base for several international telescopes, with SALT being the most prominent.
Understanding the Southern African Large Telescope (SALT)
The Southern African Large Telescope (SALT) is the largest single optical telescope in the Southern Hemisphere. Situated near the town of Sutherland in the Northern Cape province, it features a hexagonal primary mirror array measuring 11 metres across. Completed in 2005, the telescope is designed to detect light from distant stars, galaxies, and quasars that are a billion times too faint to be seen with the naked eye.
The IUCAA-SALT Partnership and Technical Contributions
India’s formal involvement with SALT began in 2007 when IUCAA joined the international consortium that funds and operates the facility. Other major partners include South Africa, the United States, the United Kingdom, Poland, Germany, and New Zealand. This partnership provides Indian astronomers with guaranteed observing time on one of the world’s most powerful telescopes.
Beyond observational access, Indian scientists have made significant technical contributions to the telescope’s instrumentation. A key example is the development of the SIDECAR Drive Electronics Controller (ISDEC), a sophisticated system used for data acquisition and control in SALT’s advanced spectrographs. Currently, Indian and South African engineers are collaborating on a new camera detector and controller system, which is slated for installation as a major technological upgrade in the coming months.
Role of IUCAA in India’s Astronomy Landscape
The Inter-University Centre for Astronomy and Astrophysics (IUCAA) is a premier autonomous institution located in Pune, Maharashtra. Established in 1988 by the University Grants Commission (UGC), it was envisioned as a center of excellence to promote research and teaching in astronomy across the Indian university system. The institution was brought to life by renowned astrophysicist Prof. Jayant Narlikar, who served as its founding director.
Located on the campus of the Savitribai Phule Pune University, IUCAA provides state-of-the-art facilities for researchers and coordinates with various universities to foster a culture of high-end scientific inquiry. It plays a pivotal role in India’s participation in major global projects, including the Square Kilometre Array (SKA) and the Laser Interferometer Gravitational-Wave Observatory (LIGO)-India. By partnering with international facilities like SALT, IUCAA ensures that Indian academia remains at the forefront of global astronomical discoveries.
Science as a Pillar of BRICS Cooperation
The astronomical collaboration between India and South Africa is a key component of the broader BRICS (Brazil, Russia, India, China, and South Africa) scientific agenda. With India holding the BRICS chairship in 2026, the focus on joint space and astronomy initiatives has intensified. Scientific cooperation within this bloc aims to leverage shared data and infrastructure to address global challenges and advance human knowledge.
Looking ahead, the partnership is set to deepen with several high-level meetings scheduled for later in 2026. India will host the BRICS Astronomy Working Group Meeting, as well as the SALT workshop and board meeting in October and November. These gatherings will serve as platforms for scientists from member nations to discuss future upgrades, data-sharing protocols, and the next generation of collaborative research projects in the Southern Hemisphere.
