Transit of Mercury

This is when Mercury is between the Earth and the Sun. It is happening on May 9, so don't miss it. It you are on the other side of the planet, then you can go watch it on lifestream, and there will be live stream. This only happens about once in every eight years, so seize the opportunity. Venus also transits the sun since it it closer to the sun than Earth is but its transit already passed; in 2012. Its next transit don't occur until 2117, so unless you have extremely good health and live for another 101 years, you won't be able to see Venus transit the sun.
