The coming blindness of astronomy

Fried Egg Nebula

The European Southern Observatory today released this infrared image today of what astronomers have named the Fried Egg Nebula. Taken by the Very Large Telescope in Chile, the picture shows the concentric dust shells surrounding a post-red supergiant star, thought to be transitioning to the next stage of stellar evolution called a yellow hypergiant. As the press release explains,

The monster star, known to astronomers as IRAS 17163-3907, has a diameter about a thousand times bigger than our Sun. At a distance of about 13 000 light-years from Earth, it is the closest yellow hypergiant found to date and new observations show it shines some 500 000 times more brightly than the Sun. . . . If the Fried Egg Nebula were placed in the centre of the Solar System the Earth would lie deep within the star itself and the planet Jupiter would be orbiting just above its surface. The much larger surrounding nebula would engulf all the planets and dwarf planets and even some of the comets that orbit far beyond the orbit of Neptune. The outer shell has a radius of 10 000 times the distance from the Earth to the Sun.

Yellow hypergiants are in an extremely active phase of their evolution, undergoing a series of explosive events — this star has ejected four times the mass of the Sun in just a few hundred years. The material flung out during these bursts has formed the extensive double shell of the nebula, which is made of dust rich in silicates and mixed with gas.

According to the science paper [pdf] describing this research, the stage of yellow hypergiants is a preliminary to the star evolving into a luminous blue variable, of which Eta Carinae is the most famous. In this next stage a star is thought to have a good chance of going supernova.

Though this image is truely spectacular, taken by a ground-based telescope of a star 13,000 light years away, what I find most significant about this image is its fuzziness. It reminds me of the kind of images astronomers and the public routinely accepted as the best possible, before the launch of the Hubble Space Telescope.

NASA proposes major reconstruction of its launch facility at the Kennedy Space Center

9:25 am

NASA proposes major reconstruction of its launch facility at the Kennedy Space Center.

They say this modernization is intended to make Kennedy more competitive in the modern commercial space market, which I am sure is true. Another way to look at it, however, is that Kennedy is getting favored treatment by the government, receiving a huge subsidy from NASA that the other private spaceports in New Mexico and elsewhere were not even allowed to compete for.

Orbital Sciences has launch success

9:19 am

Orbital Sciences has a launch success, putting an Air Force reconnaissance satellite into orbit from the Kodiak Launch Complex in Alaska.

For Orbital, this success cleans off some of the stain left on the company from the recent launch failures of its Taurus 1 rocket. What would leave the company stainless, however, will be a successful first launch of its new Taurus 2 rocket, needed to carry its Cygnus capsule to ISS and scheduled for late this year.

NASA science administrator Ed Weiler is retiring after 33 years

9:12 am

Science administrator Ed Weiler is retiring after almost 33 years at NASA.

Among Weiler’s many achievements, he was crucial to getting the Hubble Space Telescope launched. Even more important, though others had conceived the idea of using the shuttle to maintain Hubble, he designed the maintenance schedule for the telescope. Seven years before it was launched, he insisted that a regular schedule of repair missions be placed on the shuttle manifest. He also insisted that a duplicate of the telescope’s main camera be built, so that if anything went wrong with the first a repaired unit could be launched quickly. It was his foresight here that made the first repair of Hubble in December 1993 go so smoothly. For this, astronomers will always be grateful.

Loreena McKennitt – The Stolen Child

8:01 pm

An evening pause: William Butler Yeats’ poem, The Stolen Child, set to song.

Away with us he’s going,
The solemn-eyed:
He’ll hear no more the lowing
Of the calves on the warm hillside
Or the kettle on the hob
Sing peace into his breat,
Or see the brown mice bob
Round and round the oatmeal-chest.

For he comes, the human child,
To the waters and the wild
With a faery, hand in hand,
From a world more full of weeping
than he can understand.

Democratic governor suggests the next Congressional election should be suspended

5:53 pm

North Carolina Democratic governor Beverly Perdue suggested that the next Congressional election should be suspended.

I think we ought to suspend, perhaps, elections for Congress for two years and just tell them we won’t hold it against them, whatever decisions they make, to just let them help this country recover.

I wonder why she really suggests this? Could it be because the Democrats are unpopular and risk losing more seats in 2012 than they lost in 2010?

Virtual monkeys typing Shakespeare

3:32 pm

A computer programmer has created a legion of virtual monkeys programmed to randomly type until the works of Shakespeare are reproduced.

If the nine-letter sequence appears anywhere in one of Shakespeare’s writings, it is matched against the relevant passage in a copy of the Bard’s complete works, and is checked off the list. The monkeys, which started typing on August 21, have already completed more than five trillion of the 5.5 trillion possible nine-letter combinations, but have so far only finished one whole work.

They appear to be doing better than Congress’s attempt to balance the federal budget.

No House Democrat will sponsor Obama’s job bill, preventing it from being introduced

11:48 pm

Boy, does this tell us how politically weak Obama has become: No House Democrat will sponsor Obama’s job bill, preventing it from being introduced for consideration.

Correction: it turns out that a Democrat did finally introduce Obama’s jobs bill to the House, though it took until September 22, three weeks after the President’s speech first demanding that Congress “pass this bill immediately.”

Veterans Administration Settles with Veteran’s Groups at Houston National Cemetery

10:36 pm

A victory for freedom: The Veterans Administration has settled the lawsuit filed against it by veteran’s groups at Houston National Cemetery over the VA’s attempt to stifle prayer at funerals. The key terms of the settlement:

  • The VA will not interfere with prayers during burial services.
  • The VA will not edit or control the speeches of speakers at ceremonies or events at the cemetery containing religious messages or viewpoints and cannot ban religious words in verbal communications between the volunteers and veteran’s families.
  • The VA will not ban religious speech or words like “God” or “Jesus” in condolence cards or gifts.
  • Payment by the VA of the veterans groups’ $215,000 in legal fees.

That it took a court suit to make the First Amendment clear to the VA is beyond sad.

Doctors rejecting the AMA over its support of Obamacare

10:23 pm

Repeal it! Doctors in large numbers are rejecting the AMA over its support of Obamacare. More significantly,

In February, the National Physicians Survey discovered that more than three times as many doctors believed that the quality of American health care would “deteriorate” rather than “improve” under ObamaCare. Nine of ten physicians think ObamaCare will have a negative impact on their profession.

Petition to repeal Obamacare on White House website

2:31 pm

Want to repeal Obamacare? Well, someone has posted a petition to repeal the law on the White House’s own website.

Essentially, the new White House petition website allows anyone to create a petition. Once it reaches 150 signers it becomes public. Once it reaches 5,000 the administration promises an official response.

What will the White House say if their own website is overwhelmed with signatories to a petition calling for the repeal of Obamacare? To find out I’ve added my name. You should to!

Obama: “You’ve got a governor whose state is on fire denying climate change.”

1:58 pm

Obama on Sunday at a fundraiser, attacking Rick Perry: “You’ve got a governor whose state is on fire denying climate change.”

Here is another example of a politician making a fool of himself. The wildfires in Texas have nothing to do with climate change. And if Obama thinks they do, he immediately shows himself to be completely ignorant of the science behind the Earth’s climate.

Faster than light?

10:05 am

Can neutrinos travel faster than light? After three years of gathering data, an experiment at CERN says they do, though by only a tiny amount.

[Physicist Antonio] Ereditato says that he is confident enough in the new result to make it public. The researchers claim to have measured the 730-kilometre trip between CERN and its detector to within 20 centimetres. They can measure the time of the trip to within 10 nanoseconds, and they have seen the effect in more than 16,000 events measured over the past two years. Given all this, they believe the result has a significance of six-sigma — the physicists’ way of saying it is certainly correct.

You can download and read a preprint of their paper here.

What I find intriguing about this result, other than its exciting groundbreaking possibilities, is how it illustrates sharply the contrast between normal and healthy science, and the sad and sick state of the field of climate science.

New York Mets – September 24, 1969

8:01 pm

An evening pause: In 1969 the lowly New York Mets, doormats in the National League from the moment the team was created in 1962, came out of nowhere to win the pennant and the World Championship of baseball. Forty-two years ago tonight I and my friend Lloyd attended the game in which the Mets clinched first place in the National League Eastern Division. Below is video showing highlights of the game plus the final out, with the crowd pouring onto the field. Though you can’t see me, I am in that crowd, jumping for joy at this most unlikely sports miracle. There was no rioting, only happy fans chanting “We’re number one!” in exuberant disbelief.

And I still have that small piece of turf from Shea Stadium, collected on that night, proof that the unexpected and improbable is always possible.
