NPR: Thanks to NASA’s Lunar Reconnaissance Orbiter, there are so many photos of the Moon streaming to Earth that scientists can’t keep up. So Oxford astrophysicist Chris Lintott has set up a website, MoonZoo, where anyone can log in and get trained to review and classify the tens of thousands of Moon photos. Among other things, participants will count the number of craters in an image and look for craters with boulders around the rim. This is the second citizen science project that Lintott has launched; in 2007 he launched GalaxyZoo to categorize images from NASA’s Hubble Space Telescope.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
