The Crab Pulsar Wind Nebula (also known as a plerion, or synchrotron nebula.) At the heart of the Crab Nebula lies a pulsar, a spinning, stellar scale object with the density of a neutron, left over as the result of a supernova, in particular one caused by the collapse of a massive star. This Chandra X-ray image clearly shows some of the structure surrounding the Crab's pulsar. As usual, this is an APOD image.

Merry Christmas (and goodbye Eartha Kitt)
Eartha Kitt's death was announced today. I think that's a very sad thing. I recommend staying with the video all the way through "Old Fashioned Girl" to hear "Santa Baby" sung by the first, and the best, interpreter of that song. Not to mention the little poke she takes at Madonna's ill-considered attempt at the tune.

Saturnebula!
Fomalhaut b. It's the first visible light image of an extrasolar planet. Though it's just a speck in this image, it's an incredible milestone. Fomalhaut itself is one of the brightest stars in the sky, located about twenty-five light years from earth in the constellation Piscis Austrinus. I'm not sure the toroidal dust disk surrounding Fomalhaut, imaged here, really counts as a nebula, as such; being apparently an analog of the Kuiper belt surrounding the Sun. However, this is such a cool discovery that bending the definition to be sure it's included in this feature seems perfectly justified. The sharp definition of the inner boundary of the cloud was one of the clues that led to the conclusion that there was a planet here to be found. The planet itself is thought to be three times the size of Jupiter, with a much larger ring system than Saturn - which might, in fact be what was actually imaged here.

Saturnebula!
Just when I think the good images of galaxies are starting to dry up, this comes along. For those who aren't aware, the Hubble Space Telescope had been offline. After having been brought back online, this was one of the first images (within the first couple of days, at any rate) captured - a pair of gravitationally interacting galaxies known as ARP 147. A spectacular pair of ring-shaped galaxies, one face on, one nearly perpendicular to our viewpoint. This is an APOD image, you can click through for more explanation and a higher resolution view, as always.

Saturnebula!
Ok, in an effort to broaden this feature, since distinctive pictures of galaxies aren't an infinite resource, I'm rechristening (and retiming) it as Saturnebula. Yeah, it's a slightly goofy construction, but it's distinctive, and it's probably easier to post on Saturdays anyway - plenty of Friday Galactic Blogs went up on Saturdays in any case. I'll be pretty broad in my definition of "nebula," to encompass any cool galactic photos I find, consistently with older definitions like that of Messier.
This particular beauty is a depiction of the Veil Nebula, the leftovers from a supernova in the direction of the constellation Cygnus at an approximate distance between 1400 and 2600 light years. It spans three degrees in the night sky (six times the apparent size of a full moon) but is notoriously difficult to see in visible light, despite an apparent magnitude of about seven, which nearly as bright as the dimmest naked eye stars (corresponding to an apparent magnitude of about six.)
It's an APOD image, and you know the drill.

The Obamaclypse Is Upon Us!
Spooky secondary effects of an election apparently leaning toward the Democrats! Mark Levin's head literally explodes!
The following pull is almost randomly selected from the gusher of a single run-on graf of stream-of-consciousness word spew. It's lucky this election is coming very soon, if only to preserve whatever sanity is left among the right-wing punditariat. Good golly.
Excerpted from The Obama Temptation:
Charles Gibson and Katie Couric sought to humiliate Palin. They would never and have never tried such an approach with Obama. But beyond the elites and the media, my greatest concern is whether this election will show a majority of the voters susceptible to the appeal of a charismatic demagogue. This may seem a harsh term to some, and no doubt will to Obama supporters, but it is a perfectly appropriate characterization. Obama's entire campaign is built on class warfare and human envy. The "change" he peddles is not new. We've seen it before. It is change that diminishes individual liberty for the soft authoritarianism of socialism. It is a populist appeal that disguises government mandated wealth redistribution as tax cuts for the middle class, falsely blames capitalism for the social policies and government corruption (Fannie Mae and Freddie Mac) that led to the current turmoil in our financial markets, fuels contempt for commerce and trade by stigmatizing those who run successful small and large businesses, and exploits human imperfection as a justification for a massive expansion of centralized government. Obama's appeal to the middle class is an appeal to the "the proletariat," as an infamous philosopher once described it, about which a mythology has been created.

While I'm at it...
Liberalism is the yin to conservatism’s yang. We need each other and can’t make America a better place without the constant tug and pull of conflict between the two ideologies. What in many countries is a source of revolution, our war of ideas with liberalism and theirs with conservatism makes us both better. It forces us to come up with new approaches to solving problems in order to compete in the marketplace of ideas. This is a free market that Obama, no matter what his proclivities, cannot shut down.
To which, I might add, nor could George W. Bush.
I haven't really followed Moran's blogging - I don't know if he always been quite this reasonable, but I'm definitely going to keep reading.
Red State of Mind
All of which leads me to this crystaline example of complete disingenuousness:
Ok, that's the setup. Now for the dénouement:Turns out, according to sources we have in Texas, that Nick Lampson's wife is not even registered to vote in Texas 22.
She lives in Beaumont, TX - at an address well outside of the district - and this is where she is registered. She's in the 2nd District, and is represented by Republican Ted Poe. The address is on Collier Road in Beaumont.
Why does this matter? Well, two weeks ago, Democrat Congressman Nick Lampson's cronies accused Pete Olson of voter fraud. They claimed he had voted improperly in a Connecticut Special Election while he was working for Texas in Washington, D.C.
Even the most basic research shut down this wacky theory. It turned out that on the day of the supposed vote, Pete Olson was traveling from Capitol Hill to Texas on Senate business in his role as Chief of Staff for Texas Senator John Cornyn. He has the airline receipt to prove it.
And as you might expect, it also turned out that Connecticut does not require a photo ID or signature from anyone casting a vote. Of course, the idea that Olson would somehow go from 1998-2005, voting like clockwork in nine different elections (according to the Democrats' own records), and interrupt it to drive up to Connecticut to participate in an unimportant special election just doesn't pass the smell test. Well, for anyone but crazy liberals who happen to be supporting Nick Lampson, like Matt Glazer and others.
Pete Olson's experience shows us why you should be required to show a government issued photo ID before voting. But let's hope Nick Lampson wasn't counting on his wife's vote - if he gets it this year, something's wrong.
So Nick Lampson's wife has a different address than he does. Somebody who might know Nick Lampson accused Pete Olsen of voter fraud. Some mumbo-jumbo about a "smell test." (Why is it that nutcase conservative demagogues insist on sniffing everything?) Et voilà an apparent opening to smear Lampson about a future event and his wife's hypothetical voting habits.
This guy makes AoS look reasonable.

LHC First Light

Last night a proton beam made its first lap of the Large Hadron Collider, with minimum drama, and almost no ending of the world. (Of course we did inch ever so closer to the Big Rip overnight, but that would have happened even without the LHC.)

Isaac Hayes
Kathy G posted this first. But it's timely, and fits a theme: songs my band covered reluctantly despite my bullheaded enthusiasm. The bastards.
Isaac Hayes was sui generis and a sublime artist.
Ok, just for contrast
This is much closer to the orginal, though it lacks Eno's wailing, screaming, siren/synth. This is how to achieve weight and power with rock and roll. Keep control of the pace, keep the energy just a hair under a boil, and hint at letting it all just crash through to the surface. Cale is masterful when he's at his best.
Sorry Elvis...
But John Cale owns this song. Though this isn't the best recorded version by Cale. That would be the version on the Slow Dazzle album. Still this is pretty nice.
Not Every Violation of the Law Is a Crime!
Not every wrong, or even every violation of the law, is a crime. In this instance, the two joint reports found only violations of the civil service laws.
So despite the far-reaching consequences of politicizing the Justice Department, despite the obvious moral hazard in letting your boss's people off easy, despite the clear violation of the law, nobody gets prosecuted. It must be nice to be defendant, judge, and jury on the same case.
We'll see if Patrick Leahy is a hero, or is just paying lip service on this one, but he's making some good mouth noises (NYT):
Mukasey's remarks "appear premature based on the facts and evidence that congressional investigators and the inspector general have uncovered so far"
Mukasey sees no need to adjust the status of employees who were hired under the flawed process. But he does encourage those were wrongfully treated to reapply.
What a guy.
These guys can't leave soon enough.
