Carl Sagan and Ann Druyan – Comet

Carl Sagan and Ann Druyan – Comet

The first edition of this lavishly illustrated book coincided with Halley’s comet’s 1986 appearance, and the second edition was timed for 1994’s Hale-Bopp comet. A further 20 years of observation—not to mention landing freaking satellites on comets and returning samples to Earth—make some of the science here dated. But Sagan and Druyan’s book contains their trademark accessibility and sense of wonder, which will never be obsolete.
