Venus Transit 2012: Live chat on how to observe the transit
The chat is scheduled for 4 p.m. with Times reporter Ron Lin, who will be fielding your questions about the astronomical event.
Tuesday, viewers across the world take part in a nearly 400-year-old astronomical obsession — tracking a familiar neighbor, Venus, as its orbit carries it directly between Earth and the sun.
This rare event, known as a transit of Venus, takes place only once every century or so, usually in pairs spaced eight years apart. The next one won't happen until Dec. 11, 2117.
So this celestial affair has sky watchers abuzz, charged with a do-or-die feeling that this is something they absolutely need to see and study.
Venues around the world will provide viewing opportunities for the public. Viewing parties offering access to outfitted telescopes are being held through the evening at the Griffith Observatory, Columbia Memorial Space Center in Downey and UCLA Planetarium, and east of the Seeley G. Mudd Building at USC. Members of the Antique Telescope Society have already set up their centuries-old viewing devices in a parking lot atop Mt. Wilson above the San Gabriel Valley, where Edwin Hubble discovered that the universe is expanding.
