Venus: Cloud 9 observatory
Venus, the second planet from the sun, isn’t very hospitable to life, to say the least. With a dense atmosphere composed of 96 percent carbon dioxide and a mean surface temperature of over 850 degrees Fahrenheit (making it hotter than Mercury, the closest planet to the sun), it’s hard to imagine it ever being a tourist destination.
But this poster does a good job of making Venus look inviting. The text reads: “See you at the Cloud 9 observatory. The best place in the Solar System to watch the Mercury transit.”
What is this transit? It takes place when Mercury passes in front of the sun, showing up as a moving black dot. It's visible from Earth, but it’s easy to imagine that it would be a lot more spectacular seen from Venus.
