POPSThe Coming Ice Age "Earth’s climate is controlled by the Sun. In comparison, every other factor is trivial. The coldest part of the Little Ice Age during the latter half of the seventeenth century was marked by the nearly complete absence of sunspots. And the Sun now appears to be entering a new period of quiescence. August of 2008 was the first month since the year 1913 that no sunspots were observed. As I write, the sun remains quiet. We are in a cooling trend."

POPSMars get it,s share :) Basically, if the Moon got some and the Earth, it's only natural that sooner of later we will find some on Mars

POPSRichard Dawkins' jaw-dropping talk on our bizarre universe Richard Dawkins discusses the question of limits on human understanding. As a species we evolved to cope with the world within a particular range of physical dimensions. These determine our common sense view of the world. How far can the plasticity of our brains transcend this limitation?

POPSLiquid flowing on surface of Saturn moon
But scientists were able to conclude the areas were liquid after studying data from a Cassini instrument able to distinguish chemically different materials based on the way they absorb and reflect infrared light. The visual and mapping instrument spotted a lake, Ontario Lacus, in Titan's south polar region during a flyby in December, NASA said. The lake is roughly 7,800 square miles, slightly bigger North America's Lake Ontario. "Detection of liquid ethane confirms a long-held idea that lakes and seas filled with methane and ethane exist on Titan," said Larry Soderblom, a scientist with the US Geological Survey in Flagstaff, Arizona. "The fact we could detect the ethane spectral signatures of the lake even when it was so dimly illuminated, and at a slanted viewing path through Titan's atmosphere, raises expectations for exciting future lake discoveries by our instrument." Scientists ruled out the presence of water ice, ammonia, ammonia hydrate and carbon dioxide in Ontario
