This site from Molecular Expressions provides a visualization of the vast distance scale in the universe. An interactive Java zooms in on a sequence of images starting as a view of the entire Milky Way galaxy and going all the way to subatomic particles. The site also provides an explanation of the convenience of exponential notation and an activity called "Perspectives: Powers of Ten."

I am a 57 year old African American male who recently enrolled in an astronomy class. I feel lost. When I was in grade school some hundred light years ago, education was a deprived comodity for me. Now that it is made available, it is difficult for me to remember all the terms. Can anyyou give me some advise for doing well in this new subject. The interrest is there, it is the comprehension that is getting in my way.
9-12: 4A/H3. Increasingly sophisticated technology is used to learn about the universe. Visual, radio, and X-ray telescopes collect information from across the entire spectrum of electromagnetic waves; computers handle data and complicated computations to interpret them; space probes send back data and materials from remote parts of the solar system; and accelerators give subatomic particles energies that simulate conditions in the stars and in the early history of the universe before stars formed.
