Apologies in advance to iOS users for pointing to a Flash-only resource, but Cary and Michael Huang’s “The Scale of the Universe” interactive page on NASA’s Astronomy Picture of the Day site is a fascinating update to the classic “Powers of Ten” video created in the 1960s by designers Charles and Ray Eames. We were particularly amused to see Boeing’s Everett, Washington aircraft plant (on the scale of Vatican City) and the virtual Minecraft world (larger than Neptune). follow link
