Before this visit I would never have guessed that a telescope could weigh 17 million pounds! Or that it takes 10 summers to paint a telescope. (When they are done, they start all over again.) The sensitivity of the system is hard to fathom. It is located in a radio free zone be cause earth-bound radio waves can create distractions.... More

This attraction was amazing. You paid $6, watched a video and saw a couple of demonstrations, then we took a bus tour of the grounds. You could buy disposable cameras in the gift shop to take as many pictures as you want. No cell phones or digital cameras allowed. It was truly something to see. They also have a cafe... More

This was an amazing place. The Exhibit Hall is full of of terrific, interactive displays. The video and presentation were informative (even for me..the most unscientific minded), great for kids 10+. I had no idea this existed, and for $6 (under 10 free), I was educated and amazed. Best value going!

It was worth a visit for the approx. hour tour and to visit the exhibit room. We spent about 1 1/2 hours there.

Admission to the display area is free but if you want to see the giant radio telescope (which you do) you have to go on a tour which does cost. Tours are on the hour and you will first watch a short video in the theater and a small science demonstration with liquid nitrogen. You will then board a shuttle... More

Enormous observatory dish so big it can hold two football fields, the only bad thing is that you can't take pictures as it disturbs the hunt for alien life in space.

While I enjoy the nerdy aspect to places such as the NRAO, today’s visit left us impressed with the size and scale of the telescopes but less than impressed with the exhibits in the hall used to explain and illustrate the process. The exhibit hall itself (and the main building for that matter) is much smaller than pictures of the... More

This facility has numerous different radio telescopes, ranging from the original 1937 garage built telescope to the world's biggest fully rotating/tilting 110 meter diameter behemoth. The visitors center is modern and very educational (not everyone understands the electromagnetic spectrum - but after visiting... More

Our tour guide was more interested in proving how smart he was than in ensuring everyone had a good tour. A child asked a question on the tour and the answer given was not even helpful to me. I'd recommend the tour as there are not many radio telescopes in the country and so it is something different. I'm glad... More

Camped here a couple weeks ago for a family oriented bike event that was awesome. Toured the installation, amazing! The satellites are HUGE! In the middle of a gorgeous valley is nestled this scientific facility straight out of Contact. The presentation was fascinating (granted I am a sucker for this kind of stuff). Grounds and buildings are really clean. Mountain... More
