Radio astronomers see black hole come to life

42 million light years away, 20 million times the mass of the Sun, and coming back to life. A team of radio astronomers, led by Dr Megan Argo of the Jodrell Bank Centre for Astrophysics, and JIVE astronomer Dr Ilse van Bemmel, are watching a previously dormant black hole wake up in a dramatic display as material falls on to it for the first time for perhaps millions of years.

€15 million boost for European astronomy

Astronomers and astroparticle physicists today are celebrating a €15 million EU funding boost for European telescopes with the launch of the ASTERICS project (Astronomy ESFRI and Research Infrastructure Cluster), which will help solve the Big Data challenges of European astronomy and give members of the public direct interactive access to some of the best of Europe's astronomy images and data.

Inauguration of JIVE as a European Research Infrastructure Consortium (ERIC)

The radio telescopes of the European VLBI Network (EVN) regularly join forces in Very Long Baseline Interferometry (VLBI) observations, in order to explore the Universe at the highest possible angular resolution, mapping out gravitational lenses, resolving supernova explosions, pinpointing black holes and measuring the flows of material and the magnetic fields close to newly born stars.

W75N Outflow Onset

Astronomers Watch Unfolding Saga of Massive Star Formation - Dwingeloo, 2 April 2015, A pair of images of a young star, made 18 years apart, has revealed a dramatic difference that is providing astronomers with a unique, "real-time" look at how massive stars develop in the earliest stages of their formation.

ERIC decision for JIVE

- 12 December 2014 - A European Commission Decision adopted today will allow JIVE, the central facility of the European VLBI Network (EVN), to become an ERIC (short for European Research Infrastructure Consortium), making this international collaboration easier and more efficient.

Sharp radio images unravel the mystery of gamma rays in stellar explosions

DWINGELOO, The Netherlands (8 October 2014) - Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery revealed a probable mechanism for the gamma-ray emissions, which mystified astronomers when first observed in 2012.

3rd International VLBI Technology Workshop

JIVE will host the 3rd International VLBI Technology Workshop in November 2014.

Spectacular supernova’s mysteries revealed

DWINGELOO, the Netherlands (22 August 2014) New research by a team of European-based astronomers is helping to solve the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year.


DWINGELOO, The Netherlands (25 June 2014) - Astronomers have discovered three closely orbiting supermassive black holes in a galaxy more than 4 billion light years away. This is the tightest trio of black holes known to date and is remarkable since most galaxies have just one at their centre (usually with a mass between 1 million to 10 billion times that of the Sun).

JIVE director lectures on brightness and transparency

On 28 Februray 2014 Prof. Dr. H.J. van Langevelde, JIVE director, presented his lecture on galactic radio astonomy at the Leiden University. In the first part of his lecture he explains to the, mostly Dutch, audience his use of interstellar masers in the field of galactic radio astronomy. The second part of his lecture, in English, focussed on policy aspects.
