Enormous labyrinth terrains crisscross the surface of Saturn's largest moon, Titan.
As methane and ethane rain down, they slowly carve away at the landscape by some undetermined method to create mazes that stretch for tens of kilometers. New research has revealed how extensive these puzzling mazes are on Titan's surface, and provides insight into how they formed.
First spotted by NASA's Cassini mission in 2010, the labyrinths bear a faint resemblance to geographic features found on Earth, in places like Papua New Guinea and China, as well as on Mars . Cassini only recently completed mapping the surface of Titan , revealing that the mazelike features make up a little over 1 percent of the moon's landscape.

"When we first saw them, we knew the terrain was special," Cassini team member Michael Malaska told Space.com. Malaska, a planetary geologist at NASA's Jet Propulsion Laboratory in California, presented efforts to characterize the labyrinth terrain at the Lunar and Planetary Science Conference (LPSC) in The Woodlands, Texas, in March. At the same meeting, Thomas Cornet, a researcher at the Saclay Nuclear Research Center in France, modeled how parts of the alien landscape might dissolve to form the labyrinth features.
Achieving a perfect score in the 1980s video game Ms. Pac-Man is something to brag about, which is probably what Microsoft's artificial intelligence is doing right now, assuming it actually knows how to brag.
Entrepreneur Don Panoz, founder of the Panoz motorsport and sports car brand, as well as the DeltaWing project, is back with yet another automotive startup, this time focused on electric car development.
If you were one of the many who diligently tuned in to watch NASA's fancy cloud-building canisters deploy from its rocket and create a bunch of colorful wisps in the atmosphere, you were undoubtedly disappointed to learn that nature's own clouds had ruined the party. NASA was forced to postpone the experiment, which is a bummer, but the good news is that it's back on track for tonight, and you can still watch it live.
