ハーシェル宇宙望遠鏡
The main area of research in Tuorla is active galactic nuclei; about half of the researchers are working on the topic. Other areas are dark matter, cosmology, astrodynamics, binary stars, solar neighborhood, solar physics and astrobiology. The optical laboratory (Opteon) produces high quality optics for telescopes. In particular, the main mirror of the ESA spacecraft Herschel Space Observatory was ground and polished at Tuorla.
