The largest Radio Observatory in the World. First place sending signals to aliens. Great place to visit. It’s a must! One day trip.

This is the largest radio telescope in the entire world, right in our backyard. It's in a remote location in Arecibo, but worth an afternoon visit. It's a once in a lifetime experience and you will learn alot about the work and all the data that is collected there.
