The mapping of the atmospheres and surfaces of some extrasolar planets, even at distances of many light years, is now possible.
Set to launch before year’s end, construction of China’s next lunar probe, Chang’e 2, appears to be on schedule, at least according to Chinese news sources.
Two stories from the so-called “city of brotherly love”:
First, a woman whose son was murdered decided she needed to protect herself. She legally obtained a concealed carry permit and purchased a gun, only to have the police come to her home, arrest her, and confiscate it. Key quote:
“I thought they were coming to my door to tell me they had my son’s murderer,” [the woman] said. “But they were coming to take me and my gun, and now I’m defenseless.”
In the second story, it appears that Philadelphia police are making a policy to arrest security guards and confiscate their guns, even though the guns were lawfully obtained and legally permitted. At least nine different security guards have experienced this form of Philadelphia thuggery. Key quote from Lieutenant Fran Healy, special adviser to the police commissioner:
“Officers’ safety comes first, and not infringing on people’s rights comes second.”
By the way, Philadelphia is the same city that now wants to charge a $300 business license for anyone writing a blog, regardless of whether they are running a business or hobby, and thus effectively stifling free speech.
An evening pause: From Stephen Sondheim’s Pacific Overture, the song “Someone in a Tree,” from the 1976 Broadway production.
It’s the fragment, not the day
It’s the pebble, not the stream
It’s the ripple, not the sea
That is happening.
Not the building but the beam
Not the garden but the stone
Only cups of tea
And history
And someone in a tree.
This amazing Hubble image, showing a strange spiral to the left of the bright star, is not of a galaxy. Instead, it is a binary star system where the material from one star is being sucked away from it by the other, thus producing the spiral pattern.
What is most fascinating about this discovery is that this kind of phenomenon has been predicted for decades, by both astronomers and science fiction writers. Consider for example this quote from Larry Niven from his short story, The Soft Weapon, where he describes what he thinks the binary star Beta Lyrae might look like:
There was smoke across the sky, a trail of red smoke wound in a tight spiral coil. At the center of the coil was the source of the fire: a double star. One member was violet-white, a flame to brand holes in a human retina, its force held in check by the polarized window. The companion was small and yellow. They seemed to burn inches apart, so close that their masses had pulled them both into flattened eggs, so close that a red belt of lesser flame looped around them to link their bulging equators togehter. The belt was hydrogen, still mating in fusion fire, pulled loose from the stellar surfaces by two gravitional wells in conflict.
The gravity did more than that. It sent a loose end of the red belt flailing away, away and out in a burning Maypole spiral that expanded and dimmed as it rose toward interstellar space, until it turned from flame-red to smoke-red, bracketing the sky and painting a spiral path of stars deep red across half the universe.
The space war continues. Mike Griffin gave a speech today where he once again attacked the Obama administration’s proposals for NASA.
If you are a baby boomer who grew up in the 1960s, such as myself, there are some very safe assumptions that anyone can make about your history and political views, both during the 1960s and the decades that followed.
For example, in the 1960s you were almost certainly against the Vietnam War. You were also likely to oppose President Lyndon Johnson and his Vice-President Hubert Humphrey. You cheered Eugene McCarthy’s anti-war campaign for President, and you probably also despised President Nixon and passionately wished that George McGovern had won the 1972 Presidential campaign.
Almost certainly you participated in some anti-war protests somewhere during the 1960s. Some of you were in Chicago for the protests during the Democratic National Convention in 1968, while others were likely to have participated in the numerous university sit-ins that were rampant throughout the country in the late 1960s.
Sadly, many of you at that time would have probably considered the police “pigs” and the military “evil” (even if those insults seem totally unfair, disgusting, and almost unforgivable to you now).
On a personal level, you probably experimented with drugs, had fun with rock ‘n roll, and even more fun with sex. Many of you also probably participated in the hippie culture at events like Woodstock and places like San Francisco and the Lower Eastside of Manhattan.
Above all, you abhorred authority. You were raised to be very independent-minded and » Read more
A new climate theory: The Pakistani floods and Russian heatwave this summer might explain why the hurricane season going on right now in the North Atlantic started off so slow.
Back to the drawing board! Though the theories say it can’t happen that fast, scientists have found evidence that 16 million years ago the Earth’s magnetic field flipped polarity in less than five years. Even more depressing for the theorists is that this is the second such fast flip researchers have discovered.
Profile in courage: Danish cartoonist Kurt Westergaard was given an award in Germany yesterday at a freedom of the press conference. Key quote:
“It does not matter if we think his cartoons are tasteful or not, if we think they are necessary and helping or not,” [German Chancellor Angela] Merkel said at the ceremony in the city of Potsdam. The question, she said, was, “Is he allowed to do this? Yes, he is.”
Westergaard’s drawing is below. Though it might offend some, the drawing of a cartoon is never justification for violence. That so many Muslims seem to think their religion justifies such violence, however, tells us a great deal about the nature of that religion.
An evening pause: The opening from the 1964 film, Robinson Crusoe on Mars. Though quickly dated by real events in the 1960s space race, this entertaining and surprisingly rational film shows how a determined man can survive, if he simply uses his brain.
Freedom of speech alert: Despite having gotten permission to be there, campus officials ejected students and members of the Young American’s for Freedom from the Palm Beach State College campus during club rush, apparantly because the officials disagreed with the students’ literature. Key quote:
On the day of club rush, officials approached the group and after seeing information about the organization and its ideals criticizing Barack Obama’s economic policy, Ms. Ford-Morris was visibly disturbed by the material presented, published by the Heritage Foundation, criticizing President Obama’s administration. College officials then called the campus police to assure the group left campus. Ms. Ford-Morris denied having ever talked to Ms. Beattie about giving permission to the organization to be a part of PBSC club rush.
Update: The name for Young American’s for Freedom has been corrected. Thank you, readers!
Deep Impact gets its first look at its next target, Comet Hartley 2. The closest approach is set for November 4.
On August 18, 2010, the Mars rover Opportunity took this panorama image of the Martian terrain. Up close, patches of bedrock can be seen where the sand had blown clear. In the far distance the rim of Endeavour Crater, the rover’s long term destination, pokes up over the horizon.
Update: A press notice from JPL today notes that Opportunity has now traveled about half of the 11.8 mile distance to Endeavour Crater. As it took two years to go this far, the journey still has two years to go, assuming the rover survives that long.
The Sun continues to show a reluctance to come out of its solar minimum. Today NOAA’s Space Weather Prediction Center published its monthly graph, showing the sun’s developing sunspot cycle in comparison with the consensis prediction made by the solar science community in May 2009. As you can see below, actual sunspot activity remains far below what was predicted by the red line.
As I noted when I posted the July and August graphs, the Sun’s ramp up to solar maximum continues to be far slower and weaker than predicted. After two hundred years of watching a vibrant and strong solar cycle, it appears increasingly likely that we are heading towards some quiet time on the Sun.
We’re here to help you: The Senate Judiciary Committee, by order of its chairman Patrick Leahy (D-Vermont), will hold hearings on September 14 to review the regulation of firearms in commerce.
Scientists develop first tractor beam, although it can only move tiny objects less than two yards. Worse, “because this technique needs heated gas to push the particles around, it can’t work in the vacuum of outer space like the tractor beams in Star Trek.”
Launchpad 39B, where 53 shuttle launches took place, is about to be torn down.
Preparations for the next shuttle flight are on hold due to a water main break.
The chart below, found here, shows current worldwide military spending as a percentage of GDP. The redder (or darker) the color, the higher the spending.
What does this tell us about Islam and the Islamic world?
The reason the Danish privately funded suborbital rocket did not launch on Sunday was because the power had accidently been cut off to an ordinary hair dryer, purchased at a Danish supermarket and installed in the rocket to keep the valve from freezing.
An evening pause: One week ago today the rocket company ATK test fired the first stage solid rocket motor of the Ares I rocket. At the moment, no one knows if this rocket will even be built, as the Obama administration opposes it while Congress argues a variety of options. Regardless, watch this video of the test and you will understand why it is fun ito build rockets.
The Lunar Reconnaissance Orbiter has released another lunar cave image, this time showing a double pit entrance with a natural bridge between them. [Thanks to reader James Fincannon for the tip.]
From the caption: “The bridge is approximately 7 meters wide on top and perhaps 9 meters on the bottom side, and is a 20 meter walk for an astronaut to cross from one side to the other.”
A Russian astronaut has been twice denied a routine but financially important honor after returning from space, and the Russian astronaut corps might strike over it.
Alex Callage, one of the members of my gun range, has just been chosen by the Air Force to train for the Olympics as a pistol shooter. Go Alex!
The uncertainty of science: The melt rate of the icecaps is half what was previously calculated.
Collision alert! Two small asteroids are going to zip past the Earth this week, both passing closer than the Moon.
New poll news from several normally liberal news sources (Washington Post, NBC, ABC) all show that the voters are really eager to fire Congress in 2010.
A preprint paper published today on the Los Alamos astro-ph website shows further evidence of the decline in the strength of the Sun’s magnetic field over the past ten years. Extrapolated into the future, this data also suggests that the next solar maximum will be the weakest in 200 years, and that the solar maximum after that will have no sunspots at all. You can download the paper here [pdf].
