Radio astronomy

​Onsala Space Observatory provides scientists with equipment to study the Earth and the rest of the Universe. Facilities for radio astronomy are described on this web site (see links in the left column). 

The observatory's host department at Chalmers, Earth and Space Sciences, has a research group in Radio astronomy and astrophysics which is a frequent user of the observatory's telescopes and other facilites.​​

Here you can find a few examples of radio astronomical research with Onsala Space Observatory's radio telescopes.
