The transit of Venus may be finished until 2117, but videos and pictures of the phenomenon are continuing to gush all over the Internet. If you missed Tuesday's nearly seven-hour astronomical spectacle, you can get up to speed with a 39-second video from NASA's Solar Dynamics Observatory. If you've got a little more time, sit back and watch the three-minute version with a soaring soundtrack.
Another time-lapse video from the SDO team lasts just 12 seconds — but it shows one of the most scientifically significant phenomena surrounding the transit: the "Arc of Venus," an interval during which sunlight is refracted around Venus' disk, creating a "ring of fire." Close analysis of the refracted light can provide insights into the dynamics of Venus' mysterious atmosphere.
The video also gives you a taste of the optical "black drop effect" that occurs when Venus crosses the edge of the sun's disk:
Here's a jaw-dropping view of Venus crossing the edge of the sun's disk from Japan's Hinode sun-watching satellite. You can make out the thin arc of sunlight refracted by the planet's atmosphere:

Over the past couple of days, we've run lots of pictures of Venus crossing over the sun's disk, but I can't pass up the opportunity to share some of the transit pictures that were shared by Cosmic Log correspondents. Here's a selection:







Thanks to everyone who submitted pictures, including Brian Helm, Adam Rybczynski, Jim Belfiore, Jacqueline Croasdale, Tommy Fortunato, Gary Brandon, Robert Schmidt, Steve Siedentop, Justin Van Hassel, Amy LeBaron, Xihui Zhang, Christopher Klug, David Hall, Jim Walsh, Bruce Korsmeyer (from Venus, Texas!), Steve Moulding, Kevin Palmer, Don Heaton, Brian Sinofsky, Tom Rejzek, Dave Holbrook, Sean Kinslow, Ameer Hassoun, John Melson, Veronica Hernandez, Jarra McGrath, Jason Heinitz, Howard Chan, Sam Stouffer, Eric Steele, Tim Baker, Dinar Dalvi, James Owen and Andrew Lee.
We won't have to wait until 2117 for the next astronomical photo op: Keep an eye out for coming attractions, highlighted by the Delta Aquarid and Perseid meteor showers of late July and mid-August.
