A very happy birthday to a very special website!

Just a quick shout out to Astronomy Picture of the Day, which turns 15 today. I have followed them religiously for the last several years and their archive is a marvel to behold. If you listen to AstronomyCast, and you should, you will know that the last century has seen repeated fundamental transformations of our understanding of the universe. APOD documents that exciting, ongoing scientific revolution and brings it to you every day.
