The above aerial photo of the Radio Telescope Dish in Arecibo, Puerto Rico was taken by A.E. Amador and the postcard can be purchased in many locations.

You can notice that it is in the karst region of Puerto Rico, a unique limestone formation of little hills, caves, rivers.

There is a visitor center here that has set hours. Remember this is a radio telescope. It receives radio waves from the dish that are fed into a large bank of computers...... other than the computers and the radio dish there is nothing to see here ( no stars!)
