ASTRON Netherlands Institute for Radio Astronomy

ASTRON, the Netherlands Institute for Radio Astronomy, makes discoveries in radio astronomy possible. This requires not only astronomical research, but also world-class radio telescopes and continuous technological innovation. ASTRON operates two well-known observatories in the Netherlands, which rank among the world's best radio telescopes: the Westerbork Synthesis Radio Telescope and LOFAR, the Low Frequency Array.

ASTRON plays an important international role and is a world leader in the development of new instruments for astronomy. ASTRON develops the necessary technology in close cooperation with industry. This also leads to innovations in telecommunication, security and data processing. Wireless Internet also has its origins in the radio astronomy research done at ASTRON.


The Stichting Radiostraling van Zon en Melkweg (SRZM) was established on 23 April 1949. The first radio telescope at Dwingeloo was built and used by SRZM. In the 1960s, this forerunner of ASTRON initiated the development of the Westerbork Synthesis Radio Telescope (WSRT). ASTRON was given its current name in the late 1980s.
