Quick Tip...

Keep your Eclipse Shades or protective eyewear in a safe place to use when major sunspots emerge.  You never know when our nearby star will become active, allowing you to view safely the dynamic sun.  For daily solar weather reports, see

A transit of Venus is so rare that, up to June 8, 2004, no human then alive had witnessed this celestial event.  Simple as transits may seem, they are instrumental in defining our place in the cosmos.  Historically, global expeditions timed transits of Venus to quantify the size of the solar system.  In the modern era, astronomers use spacecraft and other techniques to seek earth-class planets transiting distant stars.   Then next transit of Venus is June 5-6, 2012.

"Transit of Venus dot org" will guide you to instructions for safe viewing; interactive education and hands-on activities; global observing programs for students; background information and tutorials; insights into historical endeavors and the adventures of explorers; the role of spacecraft and the search for extra-solar planets; and miscellaneous items relating to the transit of Venus.  

Google's Zeitgeist feature rated the Transit of Venus as the 
#1  Most Popular Event of June 2004.

Safety! "Do not look at the sun without proper eye protection."  While that warning is seemingly obvious, what does it mean to the person who still wants to witness the transit of Venus?  Suggested viewing techniques help you to enjoy the sight without losing yours.  Observers are still responsible for their own eye safety.
