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.

What does the start of construction of SKA mean for the project and the Netherlands?

At a historic meeting of its Council on 25 June 2021, the SKA Observatory (SKAO) saw its Member States give the green light for construction of the SKA telescopes in Australia and South Africa to commence. We spoke to Michiel van Haarlem, head of the Dutch SKA Office at ASTRON, about what this important milestone means.

Green light given for construction of world’s largest radio telescope arrays

At a historic meeting of its Council last week, the recently formed SKA Observatory (SKAO) saw its Member States approve the start of construction of the SKA telescopes in Australia and South Africa.
