Teachable Moment: This interactive website allows kids and adults to explore the scale of the universe from 10 27th power to 10to the -35th power. I love the fact that objects of the same scale are compared. Who knew that Halley's Comet was about the size of Mount Everest? Or that Ganymede was larger than Mars?
