Gener.:.l conclusions coocerning the occurence of 1ife in the universe a.re pre-
sented. It is predicted that out of 42 known stars, (including the sun} within
5 parsecs from us, only ti;ree stars have a good cba.nce of supporting
advanced living beings on their planets, if such planets exist. Three arguments
are presented for believing that the formation of r.lanets around r-tars is a
common phenomenon.

Stellar life histories are briefly discussed as well as prerequisites for a life-
supporting planet. It is suggested that most single stars of the main sequence
l)etween F5 and K5 could probably support life of an advanced form on thtl
planets revolving around thE:m. Temperature and atmosphere of Mars and
Venus are discussed in detail and speculations made as tc existence of lilc
there.

Applies current knowledge in astronomy, biology, botany, and chemistry to
i:.onsideration of theories about extraterrestrial life. Concludes that in
observable universe there must be millions of planets supporting carbon-based
life similar in principle to terrestrial forms but greatly var!ed in detail.

Press, 1940. 259 p.
Summarizes evidence on probability of life on other worlds provided by
astronomy: conditions necessary for birth of a planetary :;ystem may occur so
rarely that among the vast number of stars in any one stellar univtrse we
may expect to !ind only a very limited number that have a family of planets;
and among these families of planets, there cannot be more than a small
proportion where conditions are suitable for life to exist. Life elsewhere in
the un:.verse is therefore the exce}Xion and not the rule,
