Thanks to the Whiteboard Blog and Teachers Love SMART Boards for the link: http://www.numbersleuth.org/universe/ This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. Numerous hot points along the zoom slider allow for direct access to planets, animals, the hydrogen atom and more. As you scroll, a handy dial spins to show you your present magnification level.
