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.
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.
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.
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.
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.
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.
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.
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).
