Although Venus is only the planet second nearest the sun, its dense, toxic atmosphere traps heat in a runaway version of the greenhouse effect that warms up the Earth. As a result, temperatures on Venus reach 870 degrees F (465 degrees C), more than hot enough to melt lead.
Get ready for an intergalactic (ok, maybe intragalactic) adventure! Pop Chart Lab has distilled more than half a century of space travel into a beautiful print. The Chart of Cosmic Exploration features hand-illustrated renderings of every orbiter, lander, rover, flyby, and impactor to ever successfully slip the surly bonds of Earth's orbit. Plus all of our pretty-cool planets in our pretty-great Solar System. #colossal
When the Voyager 1 and 2 spacecraft flew by Saturn in 1980 and 1981, they were able to pay only fleeting attention to Titan, the second largest moon in the solar system (larger even than the planet Mercury) and the only solar system moon with an appreciable atmosphere. These images are from subsequent Titan flybys in 2005 and 2006. - Image credit: NASA / JPL / University of Arizona
