Arecibo Observatory

I’m in Puerto Rico for the DNS-OARC Workshop and ICANN 61 meeting. Yesterday, with some conference friends, we visited the world famous Arecibo Observatory. From it’s completion in 1963 until about mid-2016, it was the world’s largest radio telescope (at which time it was overtaken by the Aperture Spherical Telescope in China).

Here are some photos from our trip.
