"From Stargazers to Starships" follows an earlier site "The Exploration of the Earth's Magnetosphere". "Stargazers" deals with the world of gravity--of massive planets and stars, and the way spaceflight is achieved despite their strong pull. "Exploration" on the other hand looks at the hot (but usually rarefied) gases which fill most of space, which are ruled by magnetic and electric forces rather than by gravity. The polar aurora, the radiation belts, the solar wind, magnetic storms, "space weather", cosmic radiation--this is the site which tells you all about them.
