TRANSIT OF VENUS: The 2012 Transit of Venus is finished, and it lived up to the hype. The inky-black silhouette of the second planet was wondrous to behold as it slowly glided across the solar disk on June 5th and 6th. Images from around the world may be found in the Realtime Transit of Venus Photo Gallery.
For the first time, a spacecraft has taken Hubble-quality photos of a Venus transit. NASA's Solar Dynamics Observatory recorded the event from geosyncronous orbit 36,000 km above Earth's surface. Click to view sample of the data SDO gathered:
SDO was able to track Venus across the full disk of the sun using a variety of white-light and extreme ultraviolet filters. The resulting movies are not only visually beautiful, but also full of scientific potential, especially for researchers who wish to study the strange dynamics of Venus's atmosphere.
The view from Earth wasn't bad either. "I knew I would not be able to take a better image of the transit than SDO, so I had to come up with something that SDO could not do, something that is seen only through Earth's atmosphere," says Mila Zinkova of San Francisco, California. "This something was, of course, a mirage."

"The upper frame shows Venus distorted by the reafractive action of Earth's atmosphere," she explains. "In the lower frame Venus is back to her normal self. I took both pictures using a Canon Powershot SH40."
