LOFAR detects gigantic radio sources in the universe

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

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.

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.

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.

Aurorae discovered on distant stars suggest hidden planets

Using the world’s most powerful radio telescope, LOFAR, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.

Periodic Fast Radio Burst found bare, unobscured by strong binary wind

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a Fast Radio Burst after all.

Most detailed-ever images of galaxies revealed using LOFAR

After almost a decade of work, an international team of astronomers has published the most detailed images yet seen of galaxies beyond our own, revealing their inner workings in unprecedented detail.

Vidi grant awarded to astronomer Harish Vedantham

Astronomer Harish Vedantham of the Netherlands Institute for Radio Astronomy (ASTRON) and the University of Groningen has been awarded a ‘VIDI' grant of 800,000 Euros from the Netherlands Organization for Scientific Research (NWO).

The galaxy with a wagging tail

One of the most massive galaxies at the centre of the Abell 1775 cluster has a 2.5 million light-year long tail – twice as long as previously thought – that appears to be “wagging”.
