The European VLBI Network (EVN) is an interferometric array of radio telescopes spread throughout Europe (and beyond) that conducts unique, high resolution, radio astronomical observations of cosmic radio sources. It is the most sensitive VLBI array in the world, thanks to the collection of extremely large telescopes that contribute to the network.

The map to the right shows EVN and other participating stations, color-coded via:

• Yellow/Red: current operational EVN stations
• Cyan/Red: existing telescopes soon to be EVN stations
• Cyan/Blue: new EVN stations under construction
• Pink/Purple: non-EVN stations that have participated in EVN observations
• Green/Brown: non-EVN stations with whom initial EVN tests have been carried out

VLBI provides astronomers with their sharpest view of the most energetic phenomena in the universe, including expanding supernovae, pulsars, flare stars, star-forming regions in molecular clouds, the environment surrounding nearby and distant galaxies, gravitational lenses, starburst galaxies and distant active galactic nuclei.^[1]

The European VLBI Network (EVN) was formed in 1980 by five of the major radio astronomy institutes in Europe and Geodetic Dept of the University of Bonn...    READ MORE »
