The Transit of Venus. Sounds like an amusement park ride that needs a motion sickness warning, doesn’t it? Well, it’s not.
The Transit of Venus is the rare passage of that planet between the Earth and the sun, and the two-day event, which happens just twice every 113 years, will be visible from Southern California between 3 and 8 p.m. today—and not again until December 2117 (good news for your pet turtle and no one else).
Here’s where you can see it:
1. At the Griffith Observatory, where specially filtered telescopes will be available (along with astrology experts) to transit watchers from noon to midnight.
2. Online via NASA.
3. Online at Astronomers Without Borders, where a live-stream of the event will be posted along with commentary from astrologers.
Not in L.A.? The handy infographic below from TransitOfVenus.org illustrates where the spectacle will be visible from Earth and when.
One thing to keep in mind: It was good advice when Mom and Dad told you never to look directly at the sun. To see the transit safely, you’ll need to protect your eyes with proper solar filters, and, sadly, Ray Bans won’t cut it. Click here for more info on what eyewear will.
UPDATE, 3:36 p.m.: Both Astronomers Without Borders and TransitOfVenus.org are having technical difficulties. NASA Edge's live Web cast is streaming here.
