A rare astronomical event will take place TONIGHT!
The planet Venus will pass between Earth and the sun, appearing as a small black dot moving across the sun’s bright disc. It’s known as the transit of Venus, and it won’t happen again for more than 100 years!! Be advised: as with solar eclipses and any natural phenomenon involving the sun, it’s extremely important to protect your eyes. Do not look directly at the sun; the easiest advisable way to view any solar events is through a pinhole camera. From the Eastern U.S. and Eastern Canada, the first visible appearance of Venus should occur around 6:03 p.m. EDT (2203 GMT). From the Western U.S. and Western Canada, this should occur around 3:06 p.m. PDT.
There are a ton of things like local viewing parties and online events to mark the occasion. Check it out here - http://venustransit.nasa.gov/transitofvenus/
