The Interweb is abuzz over the 2012 transit of Venus, and there are tons of gorgeous images coming out, but my favorites are these two below from NASA.

From NASA's Solar Dynamics Observatory:
On June 5-6 2012, SDO is collecting images of one of the rarest predictable solar events: the transit of Venus across the face of the sun. This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.
