In Arecibo, Puerto Rico lies a great radio telescope. For 53 years, the Arecibo observatory had been the largest radio telescope on the planet, and was the largest operational radio telescope in the world for all but 10 months of its existence. Constructed in 1963, the impressively massive 305 meter (1000 foot) radio telescope helped stage significant advances in the astronomical sciences. Arecibo remained the prime telescope of the SETI (Search for Extraterrestrial Intelligence) and METI (Messaging to Extraterrestrial Intelligence) projects, both initially formulated by NASA but later formed into a nonprofit organization. The Arecibo Observatory, without a doubt, is the most famous radio telescope on the planet, having been featured in popular novels like Contact by Carl Sagan (which is my favorite book, by the way) and in popular movies like Contact (again, by Carl Sagan, and again, also my favorite movie) and James Bond, and in popular TV shows like The X-Files. The Arecibo Observatory lives in fame for its astonishing contributions to the advancement of the astronomical sciences, but it appears that all great things come to an end.
