The 54th Carnival of Space, that is, hosted by David of Altair VI. That’s Altair VI the blog, not the planet. I’ve been lined up to host the event next week.
Meanwhile, here’s a Cassini radar image of the highlands of Xanadu, one of the regions identified on Titan, moon of Saturn as a quasi-continent. Scientists are assuming the meandering channels bear methane or ethane rivers. The Cassini site always gives the dimensions of these images, but I like checking my Earthling atlas for comparisons. This rectangle of Titan is a shade smaller than Iceland. (For the American-centered universe, that’s about the size of West Virginia.)
