The Senegalese Agency for Space Studies (ASES) has announced the commencement of construction works for the Astronomical Observatory of Senegal (OAS), a landmark scientific facility set to become the first astronomical infrastructure of its kind in West Africa. ASES has also confirmed that the official launch ceremony for the observatory, to be installed in Khombole in the Thiès region, will be held on 13 November 2025.

Key Observatory Features

The Observatory will comprise several advanced facilities aimed at strengthening research, training, and scientific collaboration in astronomy and astrophysics, including:

  • A 600 mm optical telescope designed for high-precision astronomical observation and the study of celestial phenomena.
  • Four C14 telescopes equipped with deep-sky research and astrophotography capabilities.
  • An Astronomy and Astrophysics Training Institute to be established for local capacitiy building and promotion of scientific research and education.
  • Modern research facilities designed to enhance observational research.

Fully remotely operated, the facility is expected to integrate seamlessly with international research networks, opening up the African skies to the global scientific community. It reflects a strategic effort by ASES to bridge the gap between education, research, and applied science, while creating new opportunities for skill development in astronomy and astrophysics.

The initiative underscores Senegal’s continued investment in space exploration and astronomy, building on earlier efforts such as SPACEBUS 2025, the country’s nationwide astronomy and space science outreach programme, as well as its participation in deep-space cooperation frameworks like the Artemis Accords and the International Lunar Research Station initiative. The construction and hosting of such a landmark astronomical facility will further strengthen Senegal’s capabilities in space and astronomical research, while also contributing to Africa’s collective advancement in astronomy and space sciences.
