How big is the Galaxy Zoo collaboration now?
Every once in a while, usually at the summer AAS meeting, the Zookeepers like to play a game called “How big is our collaboration now?” Last time, it was inspired by Chris and I attending a baseball game in St. Louis, and realizing that there were enough Galaxy Zoo volunteers to fill the stadium three times over. That led us into a discussion of “what else are we bigger than”?
Today, the Galaxy Zoo collaboration has 230,000 volunteers. How does that compare?
In terms of baseball, here is how we stack up against my home team’s stadium, Camden Yards in Baltimore (photo courtesy of Flickr user Kevin Farner, click for a larger image):
What about compared to other major milestones? Here is our list of things we are bigger than:
- Portsmouth and my hometown of Orlando
- The British Army
- The number of Quakers in North and South America
- The U.S. Libertarian Party
- …and 48 American Astronomical Societies!
Can you think of other places or organizations that we are bigger than?
