Saturn's tiny moon, Pan, was captured on March 7 during a flyby by NASA's Cassini spacecraft. The images captured during the flyby are the closest images ever taken of the moon which has an average diameter of only 17 miles.
Pan's prominent equatorial ridge gives it a distinctive flying saucer shape. The ridge is believed to be the result of material from Saturn's rings raining down on the moon.

I was in Salt Lake City on business a while back and decided to go to the Clark Planetarium and they had some extremely cool stuff.
This is a picture of a live feed they have. I have a couple short videos I took on my phone. The videos are kind of impressive, but do not even come close to doing justice to what the actual live feed looks like.

I want to know how they keep the rubber on the wheels from degrading during space flight. It's cold enough to rupture tires in space, and that thing has been in that icy coldness for two years, but it landed on its rubber wheels just fine.
It's clearly not the same material as we have on domestic car tires. Wonder what it's made of.

Tires are a black art. You can make them behave almost anyway you want by slightly tweaking the chemical compounds in the mixture, but you sacrifice other properties obviously. I've studied vehicle dynamics and some race engineering, and even those guys don't know what the hell tire engineers do half the time. That's arguably the most important part of a race car!
But really if there is no load on the tire its probably not going to crack. It's probably a couple steps up from a winter tire you get on your car.

Hibernating Aliens May Explain Why We Haven't Found Any Other Life Yet
Scientists have proposed a rather interesting reason for why we haven’t found aliens yet, a problem known as the Fermi Paradox (if life is so abundant, where is everyone?). They propose intelligent aliens could be in a state of hibernation, waiting for the universe to get colder so they can be more productive.
This idea was proposed in the Journal of the British Interplanetary Society, with a pre-print available on arXiv. The paper was written by Anders Sandberg, Stuart Armstrong, and Milan Cirkovic of the Future of Humanity Institute at the University of Oxford, and picked up recently by Gizmodo.
Some people think that a civilization much more advanced than our own might become a digital race. That is to say, they’ll live as artificial intelligence inside computers, doing away with more limiting fleshy bodies. Experts including Elon Musk have suggested this is a logical progression in the far future.
If we are not alone in the universe (which we have no evidence for yet), one could therefore further propose that an advanced alien race might have gone down this route. But in order to make the most of their new digital bodies, they might not like the universe at the moment.
The temperature of the universe right now is 3 degrees Kelvin above absolute zero. That’s rather chilly, but that temperature will continue to drop as the universe expands. Sandberg and his colleagues argue that the temperature in the future could allow for 1030 more computational processes than are currently possible.
“We hence suggest the 'aestivation hypothesis',” the researchers write in their paper, adding that “the reason we are not observing manifestations of alien civilizations is that they are currently (mostly) inactive, patiently waiting for future cosmic eras.” Aestivation is basically hibernation to avoid hotter temperatures, not cooler ones.
