The Transit of Venus and Kepler Mission
On June 5th, 2012, the world watched as the planet Venus passed between the Earth and the Sun. The Transit of Venus only occurs twice every 120 years, and this was only the 7th occurrence since the invention of the telescope. Transits are a way for astronomers to measure planets and even discover new ones. NASA's Kepler mission is discovering new planets outside of our solar system.
