Have you 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, astronomer to the stars.
Watson has taken the many, many questions that have been asked by
listeners of his popular, long-running radio shows, and answered them
in Why Is Uranus Upside Down?
This highly entertaining and informative introduction to our planet and
the Universe we live in is a must-read for enquiring minds of all ages.
