New Kepler results!

Scientists released additional Kepler results [pdf] today, this time describing what they are learning about the stars being observed rather than any planets that might be orbiting them. In studying each star’s minute variations of light, the astronomers can track how the star itself is oscillating like a bell ringing. From this they can do a kind of stellar seismology, finding out a great deal about what is going on inside the star. The data has thus:

  • produced the most precise measurements of the size and age of another star beside the Sun. KIC 11026764 has a radius 2.05 times the size of the Sun, and is now believed to be 5.94 billion years old, slightly older than the Sun’s 4.57 billion years. Though larger than the Sun, this star is a G-type star like the Sun. So far, Kepler has observed about 1500 solar-type stars. The astronomers are still analyzing this data, with results to follow.
  • measured the oscillations of a thousand red giant stars, ranging from slightly larger to dozens of times larger than the Sun. The larger the star, the faster the oscillation and the larger the amplitude, which in turn has confirmed the theories about how the nuclear processes in the core of stars evolve over time, shifting from burning hydrogen to helium. Since these red giants are what our Sun will be like when it reaches old age, we are thus learning something about the Sun’s future.
  • and provided the most precise measurements ever of RR Lyrae stars, a class of unusual variable stars that have puzzled astronomers for more than a century. From this data the astronomers hope to find out exactly why these stars fluctuate as they do.

Another European on trial for reporting the facts about Islam

Freedom of speech alert! Geert Wilders is not the only European on trial simply for reporting factual information about Islam and the Koran. In Vienna, Austria, feminist and anti-jihad activist Elisabeth Sabaditsch-Wolff faces prison simply because she conducted “public seminars in which she described Islamic doctrine, quoted from the Koran, and explained to her listeners what she considers the dangers of Islam.” Her trial date is now set for November 23. More information can also be found at Jihad Watch.

The website Gates of Vienna has started a campaign to support Sabaditsch-Wolff, and is asking websites and bloggers worldwide to support her. I am glad to lend my voice to her cause. Any government that wants to put a citizen in jail, merely for expressing an opinion or stating facts, should be condemned as loudly as possble. If you go to the campaign site above, you can read about the history of the case in detail as well as find ways you can lend your own support. Also, Elisabeth Sabaditsch-Wolff’s legal defense fund can be found at http://english.savefreespeech.org/ .

Closing caves for the convenience and power of the government

A variety of federal government agencies are moving aggressively to shut down human access to all American caves, including those on private property. Key quote:

In Wisconsin, where white nose syndrome has not yet appeared, wildlife managers want to get a jump on the disease by declaring G. destructans [the fungus associated with the syndrome] an invasive species, and declaring four species of bats threatened. Those designations would give wildlife agencies access to new sources of funds. They would also โ€œgive police power to the agencies to go onto private land to prevent damage to these newly named threatened species,โ€ said [Peter] Youngbaer, [white nose syndrome liaison for the National Speleological Society]. โ€œWe fear that private landowners will be fearful of allowing even inadvertent access to caves, and thus move to seal caves shut. Theyโ€™ll be causing more damage to the bats that theyโ€™re ostensibly trying to protect.โ€ [emphasis mine]

As a caver, I not only have a strong personal interest in this story, I know a lot about bats and caves from personal experience. As a science writer who has also written about white nose syndrome for Science, I am also very familiar with the present state of the science. Based on this background, I find the actions of these government officials unconscionable. As one commenter to this article very correctly noted:

“There is currently *no* evidence that humans have spread this disease, but mountains of evidence for bat-to-bat transmission. The possibility does exist that humans *could* spread it, but even at its worst a human vector would be quite statistically insignificant in comparison to the bat-to-bat transmission.

In other words, closing all caves to human access can accomplish no good, and a great deal of harm. Yet, this is exactly what these government officials and environmental bureaucrats wish to do.

Back in March 2008, soon after white nose syndrome was discovered, I wrote the following:

I am beginning to believe strongly that the situation has worrisome political overtones linked to the unstated desire of some people to limit access to caves. . . . Some people are distorting the situation for their own purposes, either consciously or unconsciously. . . . Some of those people might have an agenda (closing caves to cavers) that is entirely irrelevant to the issue of white nose.

The article above only serves to confirm my opinions from 2008. The government officials who are demanding the indiscriminate closure of caves and the unfettered control over caves on private property are not really interested in protecting or saving the bats. In fact, their actions might actually do great harm to the bats, as the closures, the regulatory restrictions, and the threat to private property will antagonize both cavers and landowners, thus guaranteeing their unwillingness to cooperate with scientists.

So what do these government officials want? As far as I can tell, what they really want is power. And they are using white nose syndrome as a hammer to gain it.

Sadly, I fear that they are going to succeed. Today’s environmental laws are rigged to their advantage. The press is generally on their side. And the opposition to this power grab is diffuse and weak.

Once again, we see the death of freedom. And it dies, not by a single devastating blow, but by the death of a thousand cuts.

Hubble marches on: Pinwheel of star formation

Despite its age (20 plus years), the Hubble Space Telescope continues to produce amazing images. The mosiac below shows the beautiful pinwheel galaxy NGC 3982. From the caption:

NGC 3982 is located about 68 million light-years away in the constellation Ursa Major. The galaxy spans about 30,000 light-years, one-third of the size of our Milky Way galaxy. . . .The arms are lined with pink star-forming regions of glowing hydrogen, newborn blue star clusters, and obscuring dust lanes that provide the raw material for future generations of stars. The bright nucleus is home to an older population of stars, which grow ever more densely packed toward the center.

It’s the out of control spending, stupid!

Watch this so-called panel of expects on MSNBC as they desperately try to figure out why why women play such a large part in the tea party movement. Totally baffled, the best these out-of-touch “gurus” can come up with is “taxes” and “women pay the family bills.”

Putting aside their blatent bigotry (“Women as we all know are smarter than men.”) and childishly shallow generalizations (“Something about finding a voice.”), these empty headed fools, emblematic of most modern elite intellectuals, can’t see the obvious elephant in the room.

It’s the out-of-control government spending, stupid! On Monday the Treasury Department released numbers showing that since Barack Obama took office just two years ago, the debt of the federal government rose by $3 trillion.

This graph, courtesy of Gateway Pundit, gives some context to the increase in the debt:

Federal Deficit since 1997

Spending was horrible under George Bush. The public was worried about it. Now spending has gone insane under President Obama, and the public is more than worried, the public is outraged and spitting nails. That these elites don’t see this either means they are incredibly stupid, or they want the country to collapse in a sea of debt. In either case, they shouldn’t have the jobs they do.

Republicans weaseling out already?

Republican senator Judd Gregg (R-New Hampshire) suggested Monday that it would be better to restructure the healthcare bill than repeal or defund it.

Idiot. I think he and the rest of the Republican Party are being as clueless as the Democrats if they think this strategy will work. They should instead pay very close attention to what Sarah Palin said on the same day about a third party threat:

“Some in the GOP, it’s their last shot,” Palin said Monday evening on Fox News. “It’s their last chance, and we will lose faith and we will be disappointed and disenchanted from them if they start straying from the bedrock principles that can grow our economy.”

I am also reminded of this prescience Iowahawk post. As he says so eloquently, “Retards.”

Have global warming scientists admitted that carbon dioxide is not the main greenhouse gas?

In a paper published on Saturday in the Journal of Geophysical Research – Atmospheres of the American Geophysical Union, scientists from the Goddard Institute of Space Studies (where scientists have generally been strong advocates of human-caused global warming) outlined the key atmospheric molecules that contribute to the greenhouse effect. Key quote from the abstract:

We find that water vapor is the dominant contributor (โˆผ50% of the effect), followed by clouds (โˆผ25%) and then CO2 with โˆผ20%. All other absorbers play only minor roles.

The scientists also noted that even if carbon dioxide in the atmosphere were to double, these percentages would not change significantly.

Does this mean that carbon dioxide is a minor player in creating global warming? This remains unclear. First, the above research is essentially only modeling, not actual data. Second, the scientists themselves note that the interplay of any two of these molecules (such as water and carbon dioxide or water and cloudiness) can have a greater effect than just one molecule alone, which makes these percentages by themselves incomplete.

Nonetheless, these results are important politically. These global warming scientists have placed themselves on record as admitting that cloudiness appears more significant that carbon dioxide in creating the greenhouse effect. And since the combination of water and clouds can have an even greater influence on the climate than either alone, the scientists are also admitting that water is by far the most important greenhouse molecule. Any future climate models as well as political action must take this fact into consideration.

Dried up lake beds on Mars?

A paper published on Saturday in the Journal of Geophysical Research – Planets of the American Geophysical Union, scientists suggest that the polygonal shaped cracks seen in the crater floors on many Martian craters could be evidence of ancient lakes. The evidence also suggests that the lakes were formed by the impact that created the crater. The energy of the impact melted underground ice to form a temporary lake inside the crater, which eventually dries out, leaving behind the polygons. From the abstract:

We propose desiccation to be a dominant mechanism for the formation of Crater Floor Polygons without ruling out thermal contraction as a possible contributor in some cases. This implies that lakes or water-rich sediments occupied the craters in the past. Many such aqueous environments have no apparent external source of water, and thus, hydrothermal processes occurring shortly after the impact event may be viable explanations for the observed evidence.

Chicago mainstream reporters threaten reporter asking tough questions of Emanuel

Updated and bumped.The police have now issued an arrest warrent against reporter Jay Levin. (This is based on his behavior in the video below. He is the reporter in the red wind breaker, threatening another reporter, William Kelly, who was asking tough questions of Rahm Emanuel.) Key quote:

This morning, I [William Kelly] filed a police report and signed an arrest warrant against Jay Levine for assault. The Chicago police have already reviewed the video and agreed that an assault was committed.

——
Is there no wonder people joke about a “state-run” media? Here, Chicago mainstream reporters threaten a reporter when he tries to ask Rahm Emanuel some tough questions. More here. Best line from CBS reporter Jay Levin:

Let him finish or I’m going to deck you!

Watch the whole video. The good stuff begins at around one minute.

Sorry that much of today’s posts relate to politics and not science or space. I can only follow the news where it takes me.

Charles Lollar vs Steny Hoyer

Steny Hoyer must be in trouble. At the Charles County Candidate Forum on Wednesday, he lowered himself to actually debate his opponents for the upcoming Congressional election, the first time I have seen this happen since I moved to his district in 1999. However, his Republican opponent, Charles Lollar, got the last word, and made Hoyer look bad.

Recent landslide on Mars

Mars Reconnaissance Orbiter has taken this image of what appears to be a recent landslide on Mars, located on the southeast wall of Zunil crater. When the landslide took place is not known, though the color suggests that it happened so recently that the debris has not yet been covered by wind-blown dust.

Two Democratic candidates try to silence their opposition

Freedom of speech alert! Rather than debate their opponents, two Democratic House candidates are trying to shut them up.

In the first case, incumbent Steve Driehaus (D-Ohio) is trying to use election laws to block an anti-abortion group from putting up billboards against him. Ed Morrissey at hotair.com has more details.

In the second case, incumbent Kathy Dahlkemper (D-Pennsylvania) is trying to get radio stations to pull the radio ads of another anti-abortion group which attack her for her healthcare vote.

In both cases, the Democratic candidates voted for the Healthcare bill, and seem to want to hide that fact now from the voters. Not only does this illustrate the contempt they have of freedom of speech, it shows us just how toxic the healthcare bill has become politically. I suspect that this law is going to dog the Democrats who voted for it for years to come.
