Scheiner, Julius (1858–1913)
Astrophysicist at the University of Potsdam who, in an 1891 essay, wrote
on the likelihood of extraterrestrial life adapting itself to a wide variety
of environments. He considered the possibility of life based on silicon
rather than carbon (see silicon-based
life). Of the other planets within the solar system, he thought it beyond
doubt that Mercury, Venus,
and Mars were inhabited, while Jupiter,
Saturn, and Uranus,
he decided, might be capable of supporting life. Since, in his estimation,
the Sun was orbited by at least three inhabited worlds, he thought it reasonable
to suppose that every other star in space should be orbited by at least
one.
