A Perseid meteor streaks down the Milky Way over the Saskatchewan Summer Star Party in the Cypress Hills of southwest Saskatchewan, at Cypress Hills Interprovincial Park, a Dark Sky Preserve. The Milky Way shines to the south. About 350 stargazers attend the SSSP every year. Observers enjoy their views of the sky at left while an astrophotographer attends to his camera control computer at right. (KEYSTONE/SCIENCE PHOTO LIBRARY/Alan Dyer/VWPics/SCIENCE PHOTO LIBRARY)
