Extract:

We are not alone in the universe. A few years ago, this
notion seemed farfetched; today, the existence of
extraterrestrial intelligence is taken for granted by most
scientists. Even the staid National Academy of Sciences
has gone on record that contact with other civilizations
"is no longer something beyond our dreams but a natural
event in the history of mankind that will perhaps occur in
the lifetime of many of us." Sir Bernard Lovell, one of
the world's leading radio astronomers, has calculated
that, even allowing for a margin of error of 5000%, there
must be in our galaxy about 100 million stars which have
planets of the right chemistry, dimensions, and
temperature to support organic evolution. If we consider
that our own galaxy, the Milky Way, is but one of at least
a billion other galaxies similar to ours in the observable
universe, the number ofstars that could support some form
of life is, to reach for a word, astronomical.
