The two-faced crust of Mars
I am always a sucker for research that uses very simple observations to come to profound conclusions, and that is definitely the case with “The dual nature of the martian crust: Young lavas and old clastic materials” by Josh Bandfield, Chris Edwards, David Montgomery, and Brittany Brand. This paper suggests that the martian crust has a dual nature, where the oldest rocks are actually softer and easier to erode, while more recently lava flows have led to much more durable terrain.

Spectacular Lava Lake Photos
Here’s a little something to keep you occupied while I try to do All The Things this week. The Big Picture has a spectacular series of photos of the world’s largest lava lake in Nyiragongo Crater in Africa. Enjoy!

Hell on Earth (and Io)
If you don’t follow the Boston Globe’s photoblog The Big Picture, you’re really missing out. The topics range widely from current events to pictures of saturn, and the photos are of course always stunning. Yesterday was an especially awesome set of photos from the indonesian sulfur mine Kawah Ijen. The photos were taken at night, and sulfur has the interesting quality that it burns blue, resulting in some spectacular and otherworldly scenes of fire and brimstone.
