All these links provide variations on the classic "Powers of Ten" zoom in/out
approach to teaching a sense of distance in the universe.
- "Quarks to Quasars" zoom in/out
- 42 orders of magnitude from quarks to the observable universe
- distances in meters (scientific notation) and also in mm, m, km, etc.
- explanation of each image
- no plug-ins required, images easy to download for a class off-line
- Florida State zoom in/out
- quarks to local galaxies (10 million light years)
- distances in meters (scientific notation) and also in mm, m, km, etc.
- very little explanation of each image
- requires java, hard to download and use off-line
- can buy a screensaver version
- Aspire zoom out
- from 1 meter (girl) to Virgo Cluster of galaxies
- distances in meters with scientific notation
- explanation of each image
- requires flash/shockwave, hard to download and use off-line
- NASA
astronomy zoom out
- NOT by powers of 10, but with one zoom for each "interesting" scale
- smallest scale is Earth, largest is observable universe
- distances in km with no scientific notation (but lots of zeroes!)
- detailed explanation of each image if you click on a link
- no plug-ins, easy to download images for off-line class
