One of my favorite astronomy sites is APOD (Astronomy Picture of the Day). There you can see a new astronomy picture every day (they didn't mess around with the name), usually something which relates to ongoing missions, or recent news stories in astronomy. Yesterday's APOD was quite unusual. I'm still trying to figure out why it counted as an "astronomy picture", being neither about astronomy, or a picture, but I liked it so much that I wanted to link to it and post it here. So here's the link with the full description: APOD for July 23rd. And below is the "picture", entitled "Happy People Dancing on Planet Earth". Neat stuff.
PS. I want to figure out how to put an APOD sidebar into my blog - like there is in the AAS Public Policy Blog. Can anyone help? I thought it would be easy, but I'm stuck!
