Leading astronomers in Australia, Britain, Holland, Puerto Rico, and the United States take part in a mammoth examination of the universe we inhabit.
Introduced by Magnus Magnusson and Ian Roxburgh

Never before, in the thousands of years for which men have wondered about the meaning of what goes on in the sky, has there been so dramatic a period of discovery as this. Astronomers have detected events of breathtaking violence which seem to defy the known forces of nature.
It's now thought likely that some stars are so utterly crushed that the earth, on the same scale would be reduced to a mere hundred yards across. Indeed, it may be that matter is being squeezed out of existence and vanishing from our universe altogether, leaving behind only a black hole of gravity, like the grin of the Cheshire Cat.
There is strange new evidence, too, on the origin of our entire universe. For the first time astronomers are on the brink of establishing its history and fate.
