The New Heavens
George Ellery Hale
A hundred-inch mirror on a California mountain opened new heavens to human eyes. George Ellery Hale traces the instruments, from early telescopes to the great reflector, that revealed the structure of the universe. Clear, visionary, and grounded in real astronomy. A guide to the tools and discoveries that expanded the cosmos. Turn the great telescopes toward the stars with the man who built them.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
