ERIS 2022 School inspires next generation of radio astronomers

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.

TOPIC-led consortium develops CSP-Low for SKA

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.

ASTRON-led consortium working on SKAO

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.

NenuFAR officially becomes a LOFAR super station

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

Westerbork and the future of GigaHertz 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.

Flurry of new discoveries as incredible new image revealing 4.4 million galaxies is made public

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.

Cosmic flashes discovered in a surprising location in space

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

Astronomers find largest radio galaxy ever

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.

Gigapixel radio image of the Universe using Europe as a radio telescope

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.

Two ERC Starting Grants awarded to (space) weather research projects with the LOFAR radio telescope

The European Research Council (ERC) has awarded two of its prestigious Starting Grants to ASTRON scientists for research projects using the LOFAR radio telescope. One project will use LOFAR to create detailed images of lightning on Earth, the other aims to detect space weather events and magnetic fields around exoplanets.

Volcanic ‘activity’ in black holes blows monumental bubbles spanning hundreds of thousands of light years

An international team of researchers, which included astronomers from the Netherlands Institutes for Radio Astronomy (ASTRON) and Space Research (SRON) as well as Leiden University, observed the full extent of the evolution of hot gas produced by an active black hole for the first time.

Inheemse blik op de hemel in Leiden tentoongesteld

Op zaterdag 16 oktober opent de bijzondere tentoonstelling Onder onze hemel (origineel Shared Sky), een culturele blik op de sterrenhemel door Aboriginal Australische en Zuid-Afrikaanse artiesten, in de Oude Sterrewacht in Leiden.

We are moving our Dwingeloo Test Station for LOFAR2.0 for the next series of tests, as part of a big #LOFAR upgrade, which will enable it to collect even more data and increase its accuracy. @RTVDrenthe visited us to take a look themselves.

2 days ago, the Sun emitted a strong solar flare, which might reach Earth today. Last August, @mabrentjens, radio astronomer at ASTRON, explained what effects these solar flares can have on our technologies.
