A Once In A Lifetime Event Holy Moly, Venus!! Remember this event this evening from 5:00 p.m up to 11:30 p.m. It won't happen in our life time again until 2117. The second half of a twice-in-a-lifetime astronomical event takes place on June 5, 2012: a transit of Venus across the face of the Sun. The planet will look like a small black dot slowly creeping across the Sun’s northern hemisphere. It will be visible across the entire United States, but you will need eye protection to view it. source:stardate.org
