This was surprisingly a highlight of our trip. We loved it! Really fascinating, the scale is amazing and they do some great talks. Combine with a morning at the caves and you'll have a day to remember

One of the biggest radio telescopes on the world. Second to the recently open China located one. So is the biggest in the Americas.
