So far, the smoggy moon looks free of impact craters, shows streakiness or wind-scouring and harbors dark boundaries against a lighter 'shoreline'. Whether the moon actually has oily lakes will not be clarified until radar and stereo views are processed in the next 24-hours. Moon Shadows http://www.astrobio.net/news/article1265.html For much of the Americas, Wednesday's lunar eclipse highlights the delicate question of whether our Moon is the thing that actually stabilizes the Earth in its habitable, climatic zone. Their complementary sizes can be observed in dramatic fashion when the Earth's shadow intersects the moon's orbit. Magical Xanadu http://www.astrobio.net/news/article1264.html The region of most interest on Titan is a continent-sized, bright area called Xanadu. Images acquired while the Cassini probe approached the moon suggest a landscape shrouded by heavy clouds and contrasting albedo. Yale Lock on Martian Ages http://www.astrobio.net/news/article1263.html A Yale geology team has tested an isotope method to correlate the age of martian meteors to how uranium and thorium decay to form helium. An important byproduct is a profile of how the rock may have been heated during its ejection or atmospheric entry.
