PRAXIS BOOKS NEW EYES ON THE UNIVERSE - STEPH...

New Eyes on the Universe - Twelve Cosmic Mysteries and the Tools We Need to Solve Them gives an
up-to-date broad overview of some of the key issues in modern astronomy and cosmology. It
describes the vast amount of observational data that the new generation of observatories and
telescopes are currently producing  and how that data might solve some of the outstanding
puzzles inherent in our emerging world view. Included are questions such as: What is causing
the Universe to blow itself apart? What could be powering the luminous gamma-ray bursters?
Where is all the matter in the Universe? Do other Earths exist? Is there intelligent life out
there? The renowned author explains clearly  without recourse to mathematics  why each question
is puzzling and worthy of research. Included in the study of the wide range of sensitive and
powerful instruments used by scientists to try and solve these problems are ones which capture
electromagnetic radiation and 'telescopes' for cosmic rays  neutrinos  gravitational waves  and
dark matter. This book discusses twelve areas of active astronomical research  ranging from the
nature of dark energy to the existence or otherwise of extraterrestrial civilizations  and
devotes one chapter to each topic. Although astronomers tackle each of these questions using
information gleaned from all possible wavelengths and sources (and this is emphasized
throughout the book)  in this work the author dedicates each chapter to a particular
observational method. One chapter covers X-ray telescopes for investigating black holes  while
another uses infrared telescopes to learn more about planetary information.
