In the news: Transit of Venus, 5 June/6 June 2012

If you miss this event, expect to wait over a century to see it again (in December 2117). A transit of Venus happens when the planet passes between us and the sun. Although the last transit occurred in 2004, the event is usually extremely rare. Use precautions—view through welder’s glass, as you would for a solar eclipse—if you plan to observe.
