Research & Innovation

Radio telescopes are used to observe our universe and to provide astronomers with detailed images and spectra. We use antenna technology to receive radio signals from the universe. There are different types of antennas: dishes like the Westerbork Synthesis Radio Telescope (WSRT), and dipoles like the Low Frequency Array (LOFAR). We require many antennas to get the sharpest images from very weak signals. Combining the signals from all antennas is called interferometry and requires electronic boards, photonic links, supercomputers and a lot of algorithms and software.

Compact Receivers

Receiver systems in radio astronomy consist of a number of components, starting with the antenna, via a number of discrete electronic components to the digital electronic boards.

High Performance Computing

A radio telescope produces a data stream for each antenna. Since we use up to hundreds of thousands of antennas, these data streams are processed in parallel.

Calibration and Imaging

Several data processing steps are necessary before data from a radio telescope such as LOFAR can be turned into a scientific image of the sky.

Science Data Centre

The SKA will generate more data than we have processed and analysed ever before. To make this possible, innovation in hardware, software and expertise is crucial.

Many of ASTRON's scientific discoveries were made with the Dwingeloo radio telescope. To tell you a bit more about this, we have published the second video in our virtual tour.

Daily image of the week. To enrich the exhibition of Nebra sky disc at the @DrentsMuseum, ASTRON hosted a stand outside, demonstrating how we explore the universe nowadays, compared to how people did this 3,500 years ago (when the Nebra disc was made).

This week is #Pride Week. A more #diverse workforce fuels creativity, compassion, understanding, and the feeling of kinship and inclusion. At ASTRON we highly value diversity and make constant efforts to increase the diversity of our workforce.

Op 7 en 14 augustus staan we voor het @DrentsMuseum, dat de #Nebraschijf, een van de oudste sterrenkaarten ter wereld tentoonstelt. ASTRON-onderzoeker @AndreOffringa geeft binnen een lezing en wij doen voor het museum wat leuke proefjes. Hopelijk tot dan!
