Today, SKA Observatory celebrates the start of on-site construction of the Square Kilometre Array (SKA).

On 17-19 October 2022, JIVE and ASTRON co-hosted the 3rd Next Generation VLBI workshop (ngSVLBI-3) in Dwingeloo, the Netherlands. The hybrid workshop was attended both in-person and remotely by about ninety participants from all over the world.

An international research team has discovered four radio sources of up to ten million light years in size: megahalos.

Over 70 students from all over the world participated in the 9th European Radio Interferometry School (ERIS 2022) hosted by JIVE and ASTRON in Dwingeloo (the Netherlands) on 19-23 September 2022.

The SKA telescopes are currently in the construction phase, and with it the central signal processor (CSP) for the SKA Low frequency telescope, called CSP-Low. CSP-Low will be integrated and delivered to site by a consortium led by the Dutch company TOPIC; ASTRON is one of its subcontractors. One of TOPIC’s specializations is designing and developing hardware, firmware, and software for sophisticated systems.

A consortium led by ASTRON is developing important software components for processing the vast amounts of data that the soon-to-be largest radio telescope in the world will produce.

The low-frequency radio telescope NenuFAR will be connected to the international LOFAR telescope, operated by ASTRON, the Netherlands Institute for Radio Astronomy.

The Westerbork Synthesis Radio Telescope (WSRT) has been a powerhouse of science since it began operations in 1968, making more than 50 years of discoveries in radio astronomy happen. Looking forward, we will strengthen our activities in Westerbork on VLBI, GNSS, data releases of the Apertif surveys, and developing next-generation technology for our instruments.

Over a seven year period an international team of scientists has mapped more than a quarter of the northern sky using the Low Frequency Array (LOFAR), a pan-European radio telescope. It reveals an astonishingly detailed radio image of more than 4.4 million objects and a very dynamic picture of our Universe.

Astronomers have observed mysterious flashes in the sky from an unexpected source, a globular cluster in the galaxy M81.

By a stroke of luck, a team led by Dutch PhD student Martijn Oei has discovered a radio galaxy of at least 16 million light-years long.

An international team of astronomers has created one of the largest and most detailed radio maps at megahertz frequencies thanks to Dutch supercomputers. This research, led by Frits Sweijen at Leiden University, has been published in Nature Astronomy on Thursday.
