Chapter 1 focuses on how Venus appears from Earth. The 584-day cycle where Venus goes through a full set of phases like the Moon is explained in detail. The fact that Venus’s phases can only be explained by a heliocentric theory and not the geocentric theory, something which was very important to the development of astronomy, is discussed.
Chapter 2 talks about the early depiction of Venus in science fiction as a world on which exotic life forms lived. It then goes on to talk about the later exploration of the Venus by spacecraft, which discovered a harsh hostile world, where the surface temperature is nearly five hundred degrees Celsius and the atmospheric pressure is a crushing 92 times that of Earth.
In Chapter 3, I discuss the ‘transit of Venus’, an astronomical event in which Venus appears to cross the surface of the Sun. Observations of the transit of Venus were critical to the development of astronomy in the seventeenth and eighteenth centuries.
The remainder of the book discusses what humans would need to do to live on Venus.
