Featured Map for 5 June 2012:
Transit of Venus 2012

The transit of a planet occurs when the planet passes between the viewer and the face of the Sun. Viewed from Earth, only transits of Mercury and Venus are possible. Venus, being relative large and close to Earth, creates a discernable, circular spot on the face of the Sun. These rare events occur in pairs, separated by eight years, with more than a century between one pair and the next. The second in a pair occurs today, starting at 22:09:38 UTC.

Today's Featured Map, created by NASA (not using the Great Circle Mapper), shows when and where today's transit of Venus will be visible.
