The LOFAR telescope shows first fringes

A team of astronomers and engineers at ASTRON, the Netherlands Institute for Radio Astronomy, has successfully detected correlated interferometric radio signals, so-called "fringes", from the sky with the first three, recently completed, full-scale LOFAR stations. Read more

Building LOFAR: CS302 - the first LOFAR station V

A cabinet is placed at each LOFAR station to house the receivers, digital processing boards and other equipment needed for the initial processing and calibration of the antenna signals. Read more

Building LOFAR: CS302 - the first LOFAR station IV

The placement of the High Band Antenna (HBA) tiles (which operate between 115 and 250 MHz) is quite an elaborate procedure. Read more

Building LOFAR: CS302 - the first LOFAR station III

Each LOFAR station has 96 Low Band Antennas (LBAs). In the Netherlands these are connected to 48 receivers, which means that half the 96 antennas can be used at any time. Read more

Building LOFAR: CS302 - the first LOFAR station II

In each LOFAR station about 25 km of coaxial cable is used for the connection of the HBA and LBA antennes. Read more

Building LOFAR: CS302 - the first LOFAR station I

The flatness requirements for a LOFAR station are quite strict and the antennas need to be placed accurately. Read more

Spectaculaire luchtfoto’s tonen bouw LOFAR

 ASTRON is deze zomer begonnen met het inrichten van het 400 hectare grote centrale gebied voor de LOFAR radiotelescoop tussen Exloo en Buinen in Drenthe. Op spectaculaire luchtfoto’s zijn de inrichtingswerkzaamheden te zien. De foto’s tonen onder andere een grote terp, de superterp genoemd. Deze cirkelvormige superterp   Read more

LOFAR picks up speed

 Het Max-Planck-Institut für Radioastronomie heeft nauw samengewerkt met ASTRON, het Nederlandse Instituut voor Radioastronomie, om het eerste internationale LOFAR radiotelescoop station te realiseren. Read more

First international LOFAR station in Effelsberg

The Max Planck Institute for Radio Astronomy has teamed up with The Netherlands Institute for Radio Astronomy, ASTRON, to realise the first international telescope station of the LOFAR radio telescope. Read more

ASTRON opent radio observatory control room

 Op 6 december opent ASTRON met een korte ceremonie haar nieuwe Radio Observatory Control Room in Dwingeloo. Vanuit deze Control Room worden de sterrenkundige waarnemingen van zowel de LOFAR als de Westerbork radiotelescoop gecoördineerd. Read more
ASTRON initiated LOFAR as a new and innovative effort to force a breakthrough in sensitivity for astronomical observations at radio-frequencies below 250 MHz.
