The Invisible Universe: The Story of Radio Astronomy (Patrick Moore's Practical Astronomy Series)

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. This revised book provides an update on the state of radio astronomy and those sections no longer regarded as cutting edge have been removed. With this book, aimed at a lay audience, you learn what astronomers are doing with those huge dishes. With each of these observatories, the scientists collect and analyze their data, "listening" to the radio signals from space, in order to learn what is out there, and perhaps even if someone else may be listening as well. Hidden from human view, accessible only to sensitive receivers attached to huge radio telescopes, giant versions of backyard satellite dishes, the invisible universe beyond our senses continues to fascinate and intrigue our imaginations. We cannot really comprehend what it means to say that a galaxy is exploding, yet that is the nature of some of the distant radio sources in the furthest reaches of space. 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. And between the stars, radio emission from a host of over 120 complex molecules radiate outward to reveal a tale about chemical processes that produce the very stuff of life. And 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. In The Invisible Universe, you learn what astronomers are doing with those huge dishes in the New Mexico desert, in a remote valley in Puerto Rico, 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 is out there, and perhaps even if someone else may be listening as well This special issue of the Advances in Experimental Medicine and Biology presents much of the research described at the recent 2nd International Tissue Engineering Conference. Held in Crete, Greece as part of the Aegean Conference Series, the 2nd International Conference was organized by Dr. Kiki Hellman of the Hellman Group, Dr. John Jansen of the Nijmegen University Medical Center, and Dr. Antonios Mikos of Rice University. The conference brought over 150 researchers from around the world to the Knossos Royal Village Conference Center in Crete from May 22 to 27, 2005.
