If you're an astronomy buff and looking for a little bit of Friday Fun, you can pore high-resolution photos of the Moon and help NASA flag and identify previously unseen craters.
Moon Zoo is an interactive project between NASA and the public, powered by the Zooniverse engine. Participants can mark craters, identify interesting features — fissures, abandoned space gear, alien outposts? &mdash and help map the surface of the Moon in unprecedented detail.
If you're going to take a break and do a little aimless browser clicking you might as well head over to Moon Zoo and be the one who discovers the long-lost Moon Death Ray of Dr Zindartha. Have a favourite and fun project to share in the vein of Moon Zoo's crowd-sourced discovery? Let's hear about it in the comments. Thanks ptsgp!
