Spectacular New Views of Saturn's Polar Vortex 49

sighted writes "Today the robotic spacecraft Cassini returned some jaw-dropping images of the odd hexagon in the planet's north polar region. The hexagon has been seen before, but the change of season has more fully revealed the feature in visible light. Cassini also zoomed in on the churning vortex at the north pole itself. The south pole features a similar maelstrom."

Student Publishes Extensive Statistics On the Population of Middle-Earth 218

First time accepted submitter dsjodin writes "There are only 19% females in Tolkien's works and the life expectancy of a Hobbit is 96.24 years. In January 2012 chemical engineering student Emil Johansson published a website with the hope for it to become a complete Middle-Earth genealogy. Now, ten months later, he has published some interesting numbers derived from the database of 923 characters. The site features a set of unique graphs helping us understand the world Tolkien described. Perhaps the most interesting ones are showing the decrease of the longevity of Men and the change in population of Middle-Earth throughout history. The latter was also recently published in the September edition of Wired Magazine."
