Hidden from human view, accessible only to sensitive receivers
attached to huge radio telescopes, the invisible universe beyond
our senses continues to fascinate and intrigue our imaginations.
Closer to home, in the Milky Way galaxy, radio astronomers listen
patiently to the ticking of pulsars that tell of star death and
states of matter of awesome densities. All of this happens out
there in the universe hidden from our eyes, even when aided by the
Hubble Space Telescope. This is the story of radio astronomy, of
how radio waves are generated by stars, supernova, quasars,
colliding galaxies and by the very beginnings of the universe
itself. The author discusses what radio astronomers are doing in
the New Mexico desert, in a remote valley in Puerto Rico, and in
the green Pocahontas Valley in West Virginia, as well as dozens of
other remote sites around the world. With each of these
observatories, the scientists collect and analyze their data,
"listening" to the radio signals from space in order to learn what,
or perhaps who, is out there as well. The author specifically
highlights enormous changes that have occurred in the field over
the past 50 years, including the political reality of radio
astronomy and what that could mean for the future.
