With the Sun beginning to warm the landscape in the southern hemisphere of the Red Planet and winds whipping up here and there forming dust devils that kick the powdery, rust-colored topsoil into the atmosphere, the Mars Exploration Rovers have been experiencing sure signs of a Martian spring this month.

I've had a fun morning of noodling around learning how to write KML files, and have produced one for Google Mars that shows you all of the Mars Orbiter Laser Altimeter tracks that cross the area Opportunity has driven through already, as well as the area of Endeavour crater.

Two nearly simultaneous announcements by scientists that they have detected entire planetary system deep in space have set the astronomical community abuzz.

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.
