Visualized: Cassini probe gets a glimpse of Saturn's shadow
The Cassini space probe has collected quite a few memories of Saturn in its eight years, swinging by the planet's moons and even listening to lighting storms. Even so, we're being treated to an uncommon sight today: the dark side of Saturn. A newly processed set of 60 images, originally taken in October, shows what the gas giant is like from near the center of its shadow. The slightly trippy color scheme stems from a mix of visible, near-infrared and violet light in the collage. Sitting in the darkness allows for more than just pretty pictures, as well -- it reveals details about Saturn's atmosphere and rings that would otherwise be obscured by sunlight. Just be sure to etch this mosaic in your memory. The last time Cassini had an opportunity for this kind of snapshot was in 2006, which rules out any quick retakes.
Alt-week 12.15.12: rivers on Titan, electric handcuffs and crashing into the moon
Alt-week takes a look at the best science and alternative tech stories from the last seven days. Space, it's the final frontier, where no-one can hear you scream in frustration at not knowing who the villain of Star Trek: Into Darkness is, as well as where 50 percent of our stories take place this week. NASA's planning to crash satellites into the moon, someone's patented an electo-shock handcuff and there's a river on Titan that you wouldn't want to canoe-down. This is alt-week.
NASA's Cassini can hear it when lightning crashes on Saturn
Some folks can fall asleep to the calming pitter patter of gentle rain. Yeah, we're not those people. But we could be swayed into a somnolent stupor if those sounds came from epic storms -- on Saturn. Captured by NASA's Cassini probe last March, this 11-second clip of AM radio-like electrostatic is actually the agency's first glimpse into storm activity on the planet's Northern Hemisphere. Alright, so we admit the recording's more of a weak 'snap, crackle and fizzy pop' than outright terror-inducing awe, but still these are the noises of another world. Would it help if we told you this storm's been raging since December 2010 and hasn't shown any signs of stopping? Shocking, we know. It's not all doom and gloom, though as the folks behind Cassini think this is simply a sign of impending summer. So basically, it's spring break at the saturnine Señor Frogs.

Cassini space probe exits safe mode just in time for its flyby of Enceladus
Apparently our faithful Windows 98 laptop isn't the only thing that goes into "safe mode" from time to time. For the last three weeks, the Cassini spacecraft has been in standby as it orbited Saturn due to a glitch, or "flipped bit," which prompted a shutdown of all but the most essential of the probe's operations. Engineers have been unable to determine what exactly prompted the error, although a subsequent examination of the vehicle's systems shows that all the spacecraft's responses were proper, paving the way for a reactivation of its instrumentation this previous Wednesday. If all continues to go smoothly, this will set the stage for a study of the moon Enceladus during a fly-by on November 30. This marks the sixth time that the spacecraft has gone into safe mode since its launch in 1997.
