Arecibo Observatory

Arecibo Observatory in Puerto Rico is a part of the National Astronomy and Ionosphere Center. This national research center is operated by Cornell under a cooperative agreement with the National Science Foundation (NSF). The observatory was conceived in 1960 by former Cornell electrical engineering professor William E. Gordon. It is the largest radio telescope in the world–the main reflector dish measures 330 meters (1000 feet) in diameter and covers an area of 18 acres.

Research at Arecibo is diverse and exciting–scientists travel from around the world to further their work with Arecibo’s facilities. They have applied the technology to a range of projects investigating planets, pulsars, quasars, outer galaxies, and dark matter.

In 1997 engineers completed a $25 million upgrade to the Arecibo facility (shown at right). A Gregorian reflector system now hangs from the main detector area 137 meters (450 feet) above the main reflector dish. The Gregorian dome contains two relfector dishes, a radar transmitter, and microwave receivers. The secondary and tertiary reflectors channel the signal from the main reflector into the receivers.

About Dr. Rex

I'm originally from Puerto Rico. I was born in Santurce and raised in Rio Piedras. Have lived in Florida since 1999. I have a doctorate degree in Medicine; completed in 1976. My Internal Medicine specialty was completed in 1979. Worked for Puerto Rico's health system until 1985. At this time, I'm happily retired after working for the federal government for almost 28yrs. I want to offer any knowledge that I have to anyone "out there" who is interested. My views are liberal in almost every sense. My knowledge is "eclectic" - a bit of everything. Music and reading are my passion. Blogging has also become a very interesting endeavor. Metaphysical topics attract me. I'm interested in news reporting human issues like injustice, discrimination and abuse - the "wrongly" affected. My intention is to bring this knowledge to an understandable level and to help anyone in need. I'm open to questions and will answer them to the best of my ability. Currently working on an enterprise whose main mission will be to bring peoples of all walks of life together. To be one .... since we ALL are ONE!! The future looks bright and promising!!!
