Snapped on my first trip outside Amsterdam in the Netherlands, this is Dwingeloo Radio Observatory. Constructed in the 1950s, it has a diameter of 25 meters which at the time made it the largest radio telescope in the world. These days it’s no longer used for research and instead just by amateur radio enthusiasts, but it’s still located right by ASTRON, the headquarters for astronomy research in the Netherlands near the village of Dwingeloo.
Honestly I will be out at ASTRON so many times over the next few years I don’t feel obliged to give a full tour yet (already scheduled to go out twice next month, once for a full week!), but I thought it was a rather nice bit of scientific history to find hiding in a remote corner of Holland.
