On June 5 (and June 6 in some places), the world gets to witness a once-in a-lifetime celestial happening -- the transit of Venus, a super-rare astronomical event in which it's possible to view Venus' passage across the sun from Earth.

Why "once in a lifetime?" The transit of Venus "occurs in a pattern that repeats every 243 years, with pairs of transits 8 years apart separated by long gaps of 121.5 years and 105.5 years," according to Bill Nye's Planetary Society. The last transit took place on June 8, 2004, and the next transit occurs on December 11, 2117.

We've already seen some great shots snapped by CNET photographer James Martin today at the Griffith Observatory in Los Angeles, but we astronomy geeks at Crave wanted to see even more. So we scoured Flickr and found a few nice people around this vast Earth willing to share shots of the silhouetted Venus journeying across the sun. We also mixed in a couple of NASA grabs for good measure.

Photographer H.L. Tam captured some amateur astronomers setting up a telescope with a solar filter at the Avenue of Stars in Tsim Sha Tsui, Hong Kong.
