We mentioned William Herschel (1738-1822)who discovered Uranus and was the first to suggest that the Milky Way was the densest part of a "Spiral Nebula".
However, he was also interested in extraterrestrial life and was convinced that life could be found on each and every body in the universe. Thus he postulated that the Moon was inhabited by civilised insects which could be observed by noting the changes on its surface. His most amazing belief, however, was that the Sun was inhabited and existed on a solid body beneath the glowing surface that we see.
His Solarians led very busy lives as because there was no night they did not need to sleep.
