Venus will transit the face of the Sun on June 5, forming a small black silhouette against the brilliant Sun. For most of the United States, the transit will be in progress as the Sun sets. Only Alaska and Hawaii will see the entire event. This is the last Venus transit until 2117. Although it is visible to the unaided eye, you need eye protection to view it safely, such as dark welder's glass. [Sun image: NSO]
