Venus Transit 2012 - by Solar Dynamics Observatory
Wrapping my mind around the sizes and distances one is seeing here... that black disk, Venus, is the same size as Earth. And in these pictures, the sun is more than twice as far from Venus as Venus is from the Earth.
Venus is our twin planet; the same size and composition, and a close companion in our orbits around the sun. But because the bulk of its atmosphere is made of carbon dioxide, an extreme greenhouse effect has ravaged the surface. Temperatures there can reach a scorching 870 degrees Fahrenheit (470 degrees Celsius).
