Shortly after 6 p.m. on Tuesday, a small black dot will begin moving across the face of the Sun, an event that is turning New York City — not usually an epicenter of astronomy — into an interplanetary kind of town, with astronomy buffs and telescope jockeys in parks, on street corners and along piers. The rare astronomical event, known as the transit of Venus, comes in pairs about once every century, with the previous one occurring in 2004. The next one will not take place until 2117, making the Spaces Science, Cities Full, Buckets Lists, Final Frontier, Point Nytimes Com, Venus Crosses, Vantage Point, Venus Transitional, Venus Sliding
Venus will transit the sun on June 5, 2012. You will be able to see this celestial event (wearing appropriate eye protection!) at dusk in the United States. This will be the one and only time you will be able to view the Transit of Venus as it will not occur again until 2117. Read technical information about the transit on the NASA website.
Venus is visible above Earth's moon, which is illuminated solely by light reflected from Earth. Because of Venus's nearness to Earth and the way its clouds reflect sunlight, it appears to be the brightest planet in the night sky. Photo: NASA
