Arecibo Observatory

This gigantic radio telescope has contributed to scientific discoveries since the 1960s, and has appeared in many movies and television shows.

The Arecibo Observatory is the world’s largest radio telescope and one of Puerto Rico’s most well-known attractions. It has featured in many Hollywood blockbusters, including the James Bond movie GoldenEye and Contact, starring Jodie Foster. 

During the past 50 years, the Arecibo Observatory has played a crucial role for researchers in the fields of radio astronomy, radar astronomy and aeronomy. Today, this icon is on the list of American Historic Place and attracts visitors from around the world wanting to learn about the scientific practices. 

Start off  at the visitors center, where the in-depth exhibit  guides you through the history of the observatory. There are lots of details to satisfy the science enthusiasts, however even novices will have their interest held. There’s an interesting twenty-minute film explaining many of the discoveries made by this gigantic telescope, and then you can join a free guided tour.

Walking through the observatory, you’ll appreciate the scale of the world’s largest radio telescope. At over 1000 feet (300 meters) in diameter, it’s a sight to behold. The location in the middle of the jungle makes for a great photograph. Ask your tour guide to point out the specific parts of the observatory that served as backdrops for movies and TV shows. After a few hours here, you’ll walk away with an appreciation of  this unique research facility as well as the role that astronomers play in the 21st century.
