The Rose
The spinning vortex of Saturn’s north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image from NASA’s Cassini spacecraft. Measurements have sized the eye at a staggering 1,250 miles (2,000 kilometers) across with cloud speeds as fast as 330 miles per hour (150 meters per second).
A fascinating short video and full explanation can be found on NASA’s site:
PASADENA, Calif. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.
In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.
Very cool. If I ever have reason to revise Communion of Dreams, I would certainly include reference to The Rose since most everything happens on and around Titan.

Via NPR, this gorgeous, stunning vid:
And while I think the music they use is wonderful, I think they missed an obvious choice …

As something of a follow-up to yesterday’s post, news today of the discovery (thanks to the Kepler mission) of three exoplanets which are very good candidates for harboring life. First, their size is within an order of magnitude of Earth’s — and, specifically, less than twice the size of Earth — meaning that they’re not gas giants such as Saturn or Jupiter. Secondly, and at least as importantly, they fall within the “habitable zone” in their star system. That’s the so-called “Goldilocks Zone” where liquid water can exist (it’s not too cold and not too hot).
This is exciting! As it is put in the article:
Two of the three detailed in the new findings in the journal Science are of particular interest: Kepler-62-e and Kepler-62-f. William Borucki, the chief scientist for NASA’s Kepler telescope, says the planets are slightly wider than Earth, but not too big. Kepler-62-e is a bit toasty, like a Hawaiian world and Kepler-62-f is a bit nippy, more Alaskan, Borucki tells the AP.
“This is the first one where I’m thinking, ‘Huh, Kepler-62-f really might have life on it,’ ” said study co-author David Charbonneau of Harvard. “This is a very important barrier that’s been crossed. Why wouldn’t it have life?”
Why, indeed?

From the opening pages of Communion of Dreams:
Jon sat there for a moment, trying to digest what Seth said. According to what pretty much everyone thought, it wasn’t possible. SETI, OSETI, META and BETA had pretty much settled that question for most scientists decades ago, and twenty years of settlement efforts throughout the solar system hadn’t changed anyone’s mind. Even with the Advanced Survey Array out at Titan Prime searching nearby systems for good settlement prospects, there had never been an indication that there was an intelligent, technologically advanced race anywhere within earshot.
It’s one of the very basic questions of space science: are we (sentient beings) unique? Rare? Common? There are a lot of ways to think about it, and here’s a nice piece on NPR discussing some of the relevant parts of the question and what we’re doing about it. An excerpt:
So, to address the first part of the question we must find out how unique the Earth is. We then should figure out how unique life, and humans, are. Fortunately, thanks to NASA’s Kepler mission, we are making huge progress in the first part of the answer. A key finding is that the majority of stars (around 70 percent) have at least one planet orbiting around them. Based on the data so far (2,740 planet candidates and 115 confirmations), Kepler scientists estimate that some 17 percent of these are Earth-size, meaning with similar mass and rocky composition as the Earth, and possibly close enough to their parent star that water, if present, could be in its liquid state.
More good news arrived on this front earlier this month as NASA authorized the construction of Kepler’s successor, TESS (for Transit Exoplanet Survey Satellite). With launch scheduled for 2017, TESS will survey a much wider area of the sky than Kepler, while focusing mostly on stars that are closer. This way, it will use spectroscopy to resolve at least part of the atmospheric composition of the exoplanets. The goal is to find telling signs of life-related compounds such as ozone, water, carbon dioxide and, if we’re really lucky, even chlorophyll. Successful detection would be very exciting, as it’d point to what optimists expect, a few fairly close Earth-like planets with metabolizing beings.
I hope I live long enough that science is able to make a definitive affirmation of life, then intelligent life, outside our own planet.
Until then, well, there’s science fiction.

I should be working in the bindery. Really.
But I came in here to send an email, then paused to check MetaFilter, and saw something which scared me. Something not exactly safe for work.
So of course, I had to share.
Welcome to the future:
That’s the business end of a, um, male sex toy.
Yeah.
And if that isn’t scary enough, here’s this bit from the actual tech article:
It also occurs to me that as amazing an experience as it is, it might be even better, in a purely physical sense, if I was given full control over it – maybe even just a series of different patterns like most girls’ vibrators have. I bring the idea up with RealTouch Director of Sales, Scott Rinaldo, and he tells me that a plan to open-source the development of third party apps is already up and running.
What could possibly go wrong?

I’ve been entirely preoccupied with a big book conservation project which landed in my lap unexpectedly and needed attention right away (and trying to keep work going on St. Cybi’s Well), but a news item I saw the other day has been kicking around in my head. Er, so to speak. It’s the notion that the quality of dental hygiene & health in the modern era is *much* worse than it was before the advent of civilization. Here’s a good passage from one of the better articles which sums this up:
Our mouths are now a gentrified shadow of their former selves. And as Carl Zimmer described earlier this week, ecosystems with an impoverished web of species are more vulnerable to parasites. He was writing about frogs and lakes, but the same is true of bacteria and mouths. The narrow range of microbes in industrialised gobs are more vulnerable to invasions by species that cause disease, cavities, and other dental problems. “As an ecosystem, it has lost resilience,” says Cooper. “It basically became a permanent disease state.”
Of course, current thinking is that this is due to a fairly radical change in diet between the two time periods, with our reliance now on domesticated grain crops.
But I know the real reason:
“He had a nutty theory that early man had been shortlived, but impervious to disease. Something about being able to trace back mutation clues to some proto-genes that suggested a powerful ability to heal.” Jackie frowned.
Yeah, that’s from almost the end of Communion of Dreams. And is a topic we’ll revisit in the prequel.
Hehehehehehehe.

OK, that last post kinda churned around in my head a bit, reminded me of something else having to do with robotics.
I didn’t post anything about this a week ago when it made the rounds, but check it out:
The ability to toss a pole back and forth like that, while flying, is pretty cool. And I bet if they can do that, then tossing a ball back and forth would also be possible — if not now, then in the very near future.
So, what I want to know is: when is someone going to come up with an honest-to-God game of “Quadrocopter Quidditch”? Should be eminently doable.
