NOVA investigates what science can do in helping to solve murder—in understanding why it occurs, and how the rate might be reduced—and explores the work of people who have the stark job of dealing with death: the police, pathologist, scientists and psychiatrists.

Sophisticated instruments used by astronomers enable earthlings to see beyond what was once the cloudy barrier of the Milky Way, to a universe of perhaps 100 billion other galaxies. NOVA takes a trip into outer space to see these clusters which are as old as time and several million light years away.
