Its main premises are in Metsähovi, Kirkkonummi, 35 kilometers west of the university's Otaniemi campus.

The observatory currently operates a 13.7 metres (45 ft) diameter radio telescope, and has an array of four 5.5 metres (18 ft) dishes to serve as a compact interferometer called the 'Metsähovi Compact Array',[1] as well as several smaller radio telescopes and instruments.

The observatory is staffed by some 20 researchers, engineers, and students, mostly from Aalto University and the Finnish Centre for Astronomy with the ESO.

The observatory observed the near-total Solar eclipse of March 20, 2015 at 11.2 and 37 GHz.
