"You Are Here" shows the cosmos as it has never been seen before. With wisdom and wonder, Potter traverses the universe from its formation to its eventual end--while exploring everything in between.

If scientists can't touch the Sun, how do they know what it's made of? And if we can't see black holes, how can we be confident they exist? From the Sun and black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery.

This book is about observing dramatic cosmic events. You might think that the observation of gamma ray bursts, cataclysmic variable star outbursts, distant supernovae, and active galactic nuclei are beyond the range of amateurs - but this is not the case.
