Metsähovi Radio Observatory

Metsähovi Radio Observatory

Metsähovi Radio Observatory is the only astronomical radio observatory in Finland.

Metsähovi’s main instrument is the 14-metre radio telescope, used around the clock, every day of the year. Its observational data is used, e.g., for studying active galaxies, the Sun, and the rotation of the Earth.

Research

The research activities at Metsähovi are concentrated on radio observations done at millimetre waves and microwaves (2-150 GHz). The main areas are solar millimeter and microwave radiation, variable quasars and active galaxies, and very long baseline interferometry (VLBI).

The research in technology includes development of data acquisition, data processing, receivers and receiving methods. Metsähovi hosts researchers and students especially from the Department of Electronics and Nanoengineering and the Finnish Centre for Astronomy with ESO.

Active galaxies

The backbone of Metsähovi's observations are the long-term lightcurves of radio-bright active galaxies at high radio frequencies. Our 37 GHz light curves span four decades for many sources.

Solar research

The Sun is the nearest star and thus a premium target for observations to understand how stars work.

Very Long Baseline Interferometry (VLBI)

Very Long Baseline Interferometry (VLBI) is a technique where radio telescopes all over the world are all observing the same source at the same time at the same frequency, thus operating as one gigantic virtual telescope.

Learn more about Metsähovi Instruments

Metsähovi operates multiple instruments for studying the universe in radio frequencies. In addition to operating and developing radio telescopes and their receivers, Metsähovi also runs extremely accurate atomic clocks and and specialized computers for interferometric observations.

Metsähovi's receiver

Metsähovi's main receivers

The essential feature of a radio astronomy receiver is the capability to detect very weak radio signals as sensitively as possible. In radio telescopes and antennas, the receiver is the central part, doing the actual data collecting.

Coordinates of Metsähovi

The location of a radio observatory needs to be known precisely. The Metsähovi 14-metre radio telescope's coordinates are one of the most accurately known in Finland. In fact, the Finnish coordinates are partly based on measurement done in Metsähovi.
