Journey through the cosmos with In Saturn’s Rings, heading to IMAX in 2014 (video)
Ever since NASA's Cassini-Huygens spacecraft entered Saturn's orbit in 2004, filmmaker Stephen van Vuuren has been enthralled with its progress. So much so that he's spent years collecting over a million insanely high-res photos from Cassini's mission and quilted them together into a 45-minute film called In Saturn's Rings. Without relying on CGI or fancy visual effects, van Vuuren has patched together a seamless visual journey through our solar system, culminating in a breathtaking view of Saturn's rings and moons. Distributed by BIG & Digital, the movie is expected to make its way to IMAX theaters sometime in 2014, though there's no word yet on a specific release date. The first official trailer dropped today, and you can watch it -- in 4K if you've got the right screen -- after the break.

NASA creates the first topographic map of Titan, Saturn’s largest moon
Scientists observing Saturn's moon Titan with NASA's Cassini spacecraft have boldly gone where no man has gone before -- visually, anyway. Using radar imagery collected from nine years of Cassini flybys, researchers were able to patch together the first global topographic map of Titan, published in the July 2013 issue of Icarus. Ralph Lorenz, a member of the Cassini radar team at Johns Hopkins, said, "Titan has so much interesting activity -- like flowing liquids and moving sand dunes -- but to understand these processes it's useful to know how the terrain slopes." In particular, understanding the moon's terrain can reveal a lot about its dynamic climate system. Like Earth, Titan's atmosphere is composed primarily of nitrogen, but the liquids and vapors on the moon's surface are made of methane and other organic chemicals integral to the creation of complex life. By studying the relationship between atmosphere and terrain, researchers hope to learn more about the evolution of life in its earliest stages, and inspire curious minds to turn their eyes toward Titan.

Visualized: Space hurricane! NASA’s Cassini records super cyclone on Saturn (video)
If the crashing sound of lightning striking Saturn wasn't enough to excite your inner-meteorologist, then perhaps footage of a raging extraterrestrial hurricane will win you over. After orbiting the ringed planet for nine years, NASA's Cassini probe has managed to snag video of a super storm on the celestial body's north pole. Cloaked by the darkness of winter, the hurricane's eye became visible as Saturn's northern hemisphere transitioned into spring. Unlike the tropical cyclones of Earth (see: Hurricane Katrina, Sandy and Irene), this furious typhoon has been spinning for several years and has winds that flow at speeds exceeding 300MPH. Further differentiating itself from our world's whirlwinds, this alien cyclone is locked to its planet's north pole and is fueled by small amounts of water vapor instead of an actual ocean. Completely in a category of its own, the hurricane's eye measures about 1,250 miles wide and is surrounded by fluffy white clouds the size of Texas. To see this Saturnian fury in all its glory, check out the video after the break and feel free to leave your gratuitous hurricane names in the comments below.
