Radio astronomers join global standards body seeking to address satellite interference
The Committee on Radio Astronomy Frequencies (CRAF) has been admitted as an I-member of the International Special Committee on Radio Interference (CISPR), the international body that sets standards to prevent electronic devices from interfering with each other.
Astronomers pinpoint the source of the brightest one-off fast radio burst ever
An international team of astronomers has localized one of the brightest non-repeating fast radio bursts (FRBs) ever observed to a nearby galaxy.

Astronomers uncover white dwarf system emitting bright radio pulses with strange rhythm
Researchers identify a mystifying Long-Period Transient with 100% polarized radio emission, suggesting new type of cosmic radio source. A team of astronomers at ASTRON, the Netherlands Institute for Radio Astronomy, has discovered a mysterious new cosmic radio source that challenges current theories about how dead stars can produce such powerful emissions. Using the LOFAR (Low Frequency Array) radio telescope, the team picked up the unusual signal as part of a study led by astronomer Sanne Bloot. This research was published today in the scientific journal Astronomy & Astrophysics.

When the launching of powerful supermassive black hole jets persists over megayears, these flows become the largest galaxy-made structures in the Universe, attaining multi-megaparsec extents. By pumping thermal, magnetic, and cosmic ray energy far beyond galactic borders, megajets affect the distribution of matter and magnetism in the Cosmic Web. Over the last years, thanks to sensitivity gains of large-scale radio surveys, such as LoTSS, it has become clear that megajets --- generally thought to be rare and cosmologically insignificant only years ago --- are not only common, but possibly the dominant source of black hole feedback to the Cosmic Web.
8th LOFAR Data School
Wed 16 Sep 2026 - Wed 23 Sep 2026
We are happy to announce that the 8th LOFAR Data School (LDS2026) will take place at ASTRON, the Netherlands Institute for Radio Astronomy (Dwingeloo, The Netherlands) from 16 to 23 September 2026. RATIONALE The goal of the school is to assist the participants in the generation and analysis of LOFAR science ready data. The school will cover the […]
