Guy Murchie, "Music of the Spheres," Dover, 1967. No edition stated--presumed first thus. 2 vols.
"The Material Universe-from Atom to Quasar, Simply Explained."
Volume I: "The Macrocosm: Planets, Stars, Galaxies, Cosmology" and Volume II: "The Microcosm: Matter, Atoms, Waves, Radiation, Relativity" both included.
Both are somewhat reading worn, with Vol. I bearing heavier wear to covers than Vol. II. Both remain in sound shape with clean text.
