Contacting ET: Our Hopes and Fears
by Leonard David, Space.com
High-tech telescopes on the ground and
in space
that perform daunting astronomical peep shows in a search for
Earth-like worlds aim to answer one of humankind's most
monumental questions: “Are we alone?”
Arguably, a more pointed question might be: “Just how crowded is
