ASTRONOMERS UNIVERSE THE INVISIBLE UNIVERSE -...

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.
