Book A contents include: stars and constellations; solar eclipses and coronas; dust clouds in space; radiant energy; galaxies in collision; shooting stars; black holes; supernovas, and much more. Book B contents include: analysis of individual planets; the use of global positioning systems; dark matter and gravity; orbits; weather satellites; life on other planets, and much more.
