This tour takes you on a journey that spans 25 orders of magnitude, beginning on Earth, looking at objects roughly one meter in size, and spanning the Universe to scales that are roughly 1025 meters in size.

The tour stops at several points and gives you an opportunity to do your own exploring at various scales - Earth scales, Solar System scales (typically measured in "Astronomical Units"), Galaxy scales (typically measured in "light years" or "parsecs"), and Extragalactic Scales (typically measured in "Megaparsecs" or millions of parsecs.)
