About Obbservatorio De Arecibo

The Arecibo Observatory is the world’s massive radio telescope.  It was introduced in 1963. Radio astronomy, Radar astronomy, and atmospheric science are the three major areas of research this observatory is used for.  The observatory became popular and gained identification when it appeared in films, television, and gaming production.  The observatory is used to study the Earth’s ionosphere and point at different positions in the sky and track those positions for an extended period as the Earth rotates.

This place is the best for people who are interested in space and science. Others might find it slightly boring. The climb from the parking lot to the exhibit and telescope might be challenging for people with mobility issues. Make sure you take the necessary precautions. There are minivans for the physically challenged to ride up to the entrance. The displays at the entrance are interactive and fun. They show a film about the history and understanding the nature of the observatory. It is a very informative movie. After the movie, you can see the radio telescope which is the best experience you will ever get. It is an amazing, beautiful, and impressive sight! If you are into science, this place should be on your travel circuit.
