is a once in a lifetime celestial event that won't happen again till 2117. But crummy weather in Smyrna-Vinings threatens to literally rain on Venus's parade.
Weatherbug says there's a 45 percent chance of rain through the day, but even if we can't catch Venus's transit across the sun in person we don't have miss it altogether. NASA is streaming live webcasts of the event from 11 different observatories across the globe.
Because the transit happens at different times for different locations, you can chose which broadcast to watch at your convenience. It's like TiVo for space.
