If you haven’t heard, 2009 is the International Year of Astronomy and, accordingly, lots of events are planned for the year. About a month ago, ESO (the European Southern Observatory) organized an event called “Around the World in 80 Telescopes” which had live webcasts from eighty telescopes in twenty-four hours. Of course, you can’t visit eighty telescopes and not include Arecibo Observatory. I can’t get the embedding to work right now, so head here to watch the video on Arecibo.

Of course, you should check out all the other telescopes, too. I’m making my way through them slowly.
