Hartebeeshoek Radio Astronomy Observatory

At HART‑RAO, researchers and visitors alike get a unique window into the cosmos. The observatory’s large radio telescopes detect faint radio emissions from distant stars, galaxies, pulsars, and other celestial objects. This allows astronomers to study phenomena invisible to optical telescopes — including radio galaxies, quasars, black‑hole jets, and the cosmic microwave background.

Beyond research, HART‑RAO plays an educational and community role. It helps foster interest in astronomy in South Africa, offering opportunities for student involvement, skills development, and public education. The data and discoveries contributed by HART‑RAO feed into global astronomical research networks, linking South Africa to international science efforts.
