This brief article describes what can be expected of the skies in the summer of 2004 with quite a few celestial thrills to anticipate. In addition to the planet viewing opportunities, there is a very rare Venus transit of the Sun and the annual Perseid meteor shower. The 2004 summer also marks both an end and beginning for the Cassini/Huygens spacecraft. It is also the beginning for Cassini/Huygens in that the exploration of Saturn will just be starting as the spacecraft enters orbit during the first few days of July. This article provides insight into the many expectations for the summer of 2004 and the best ways to view them with sections on the visible planets from May to August; celestial events; and a calendar of the moon phases. A brief list of Internet resources concludes the article.
