Coronavirus measures for ASTRON

Health comes first. That is why ASTRON is temporarily closed until at least Monday 6 April 2020. We work from home and do our best to continue our research and services as well as possible.

ASTRON will strive to continue LOFAR science observing to schedule. Users should be aware that operations are running remotely, but debugging and general support will not be as timely as you would normally expect from us.

ASTRON will strive to continue Dutch station maintenance. But there will be no international station maintenance visits until further notice. Participant visits to ASTRON, JIVE or Dutch partners is not possible.

WSRT operations will run uninterrupted.

If you have any questions, you can send an email to We hope you and your families stay safe.

LOFAR images cosmic radio monsters

Pareidolia is a tendency that pushes humans to see shapes in clouds or faces in inanimate objects. The picture shown here is a composition of four cosmic radio sources that can in fact look like a scary monster. To obtain this effect, the sources have been rearranged compared to their original position in the sky but their apparent sizes were preserved.
