  Ever wondered what dark matter is or why galaxies collide? Or why the Moon is gradually drifting away from Earth? Space is really, really big, as Douglas Adams once pointed out, and there is no better guide to it than Fred Watson, who answers one hundred questions on astronomy, such as:
  
  * Does the Earth wobble?
  
  * How do we know there is dark matter?
  
  * Do collisions of galaxies happen today?
  
  * What makes planets round?
  
  * Where is the nearest black hole?
  
  * Are there other universes?
  
  * How do we measure light years?
  
  This highly entertaining and informative introduction to our planet and the universe we live in is a must-read for science-lovers and enquiring minds of all ages.
