"Dust & Us" is a brief tour of the dark regions in galaxies that form stars and planets. This tour gives a new perspective on how important dust, which we normally think of as a nuisance, is to creating planets like the one upon which we live.
For more information and video clips related to this tour, go to the PBS NOVA Dust and Us Site which has interactives and video clips chosen in collaboration with WorldWide Telescope (WWT) scientists to provide background information for the Dust & Us tour.
