Test ranges, observatories and ground stations are a hand-picked list kept in this project rather than a published catalogue: no catalogue answers which of the world's thousands of observing sites belong on a map of it. The article below is what lets the choice be argued with.

## What it is

Onsala Space Observatory (OSO), the Swedish National Facility for Radio Astronomy, provides scientists with equipment to study the Earth and the rest of the Universe. The observatory operates two radio telescopes in Onsala, 45 km south of Gothenburg, and takes part in several international projects.
