Twice each century, a rare event takes place as Venus passes across the face of the sun.
According to NASA, the last event happened in 2004 and will occur again on June 5 and 6, 2012. Although the entire eclipse will be visible from certain countries, in the United States it will only be visible as it begins on June 5. The sun will set before the event ends.
Venus will be seen as a small dot gliding slowly across the face of the sun, the Transit of Venus website explains. Experts warn viewers to take precautions and not stare directly into the sun (see video for details).
Viewers who miss this week's event will not have another chance to see the transit of Venus. The event will not take place again until December 2117.
The Transit of Venus event will be carried live on the SLOOH space camera site. For those interested in watching the event in person, the Charlie Elliott chapter of the Atlanta Astronomy Club is holding a viewing party at Bay Creek Park in Loganville from 6-7 p.m. on June 5. Another viewing party will be held at , 3855 Fence Road in Dacula, from 5:30 p.m. to 8:45 p.m. According to the astronomy club website, three telescopes will be available at Little Mulberry for safe viewing of the transit as well as a limited number of solar glasses.
