One of the most gorgeous sights we have been privileged to see at Saturn, as the arrival of spring to the northern hemisphere has peeled away the darkness of winter, has been the enormous swirling vortex capping its north pole and ringed by Saturn's famed hexagonal jet stream.Here are the images, in glorious hi-rez [ciclops.org].
Today, the Cassini Imaging Team is proud to present to you a set of special views of this phenomenal structure, including a carefully prepared movie showing its circumpolar winds that clock at 330 miles per hour, and false color images that are at once spectacular and informative.
Last week, Rob told you how scientists announced that they'd found two Earth-like planets orbiting the star Kepler-62. One of those, Kepler-62e, now ranks as the most Earth-like exoplanet we've ever found. Of course, all of this is relative.
What I like about this chart is that it kind of shows you how "Earth-like" doesn't really mean, "Man, that is totally exactly like Earth." Instead, you should translate it more as, "Welp, this is about the closest to Earth that we've found so far." Even Kepler-62e, as you can see, is much larger than the Earth and Mars. And size matters when it comes to actual habitability. As does density — and we don't know what Kepler-62e is made of yet. It's also worth noting that #2 on this list, the infamous Gleise 581g, is really a planet candidate, rather than a planet. We aren't actually certain it exists, just yet.
Popular Science has a neat little breakdown explaining what life might be like on Kepler-62e, if we could go there. But it's worth keeping the context in mind on these Earth-like planets. Don't pack your bags just yet.
On Sunday, NASA launched three PhoneSats into orbit. House in a standard "cubesat" structures, a Google-HTC Nexus One serves as the onboard computer and sensor system, taking photos of Earth. Aamateur radio operators are monitoring the transmissions and picking up data packets that will be recombined here on Earth. According to a NASA press release, the use of commercial-of-the-shelf parts, a minimalist design, and limited mission requirements kept the cost of each satellite as low as $3500.

Two of the five planets seen circling a distant star may be capable of supporting life, reports the team operating the Kepler Space Telescope. Relatively close to Earth's size and within their sun's habitable zone, the worlds—1200 light years away—are the most tantalizing yet in a search that began in 2009. [The Atlantic]
For hand towels, astronauts get those little vacuum-packed pucks that you kind of have to unravel into a towel. But what happens when you actually put the towels to use?
Two Nova Scotia high school students, Kendra Lemke and Meredith Faulkner, submitted this experiment to Canadian Space Agency and got to see astronaut Chris Hadfield actually test it out on the ISS. The results are seriously extraordinary and you need to see them.
Want to build a DIY version of the Hubble Space Telescope? I posted last year that the Vehicle Power Interface Console used at the Goddard Flight Center during pre-launch testing of the HST was for sale on eBay for $75,000. Well, now the seller has significantly sweetened the deal by throwing in this stately and elegant two-person HST control console presumably also used during pre-launch testing.

This super special space chic fashion forward dress has a real NASA image from the Mars Curiosity Rover, also with a rover "track" print on the other side. It it made from custom printed non-fading, durable Lycra stretch fabric with a cotton stretch black backing for a lovely slimming effect. There is also a cute silver strap detail at the top. Very comfortable fabric, easy fitting.
The Curiosity lettering is hand studded with crystals for extra fanciness. You'll surely impress your friends with this one! Hem is 32" but can be adjusted if you add a note.
A television company in Holland is seeking volunteers for a one-way trip to Mars. The good news is that the sort of people who would volunteer to be on a reality TV show will be on a one-way trip to Mars.
Photographer Göran Strand created this stunning time-lapse video made from photographs of the aurora borealis as seen from Östersund, Sweden on March 17, 2013. The video consists of 2,464 images taken over four hours. The extreme intensity of the aurora borealis display resulted from a huge solar storm spurred by two solar flares that erupted on March 6.
