The blistering hot exoplanet where it snows.

These results have led to a suggestion that [HD 189733b] could continually experience silicate snow. In the lower atmosphere of [the exoplanet], magnesium silicate sublimates, that is, it passes directly from a solid into a gas. But we know there are small silicate particulates in the upper atmosphere. Formation of these particulates requires that the temperature be lowered, and so must have been formed at a temperature inversion in the atmosphere. The generally windy conditions would help some of the tiny particulates grow into respectable snow crystals.

Lord Monckton tries to educate a college professor and his students about the science of climate change.

This is why:

“We shall lose the West unless we can restore the use of reason to pre-eminence in our institutions of what was once learning. It was the age of reason that built the West and made it prosperous and free. The age of reason gave you your great Constitution of liberty. It is the power of reason, the second of the three great powers of the soul in Christian theology, that marks our species out from the rest of the visible creation, and makes us closest to the image and likeness of our Creator. I cannot stand by and let the forces of darkness drive us unprotesting into a new Dark Age.”

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

An up and down Sun

11:52 pm

close-up

Late last week NOAA’s Space Weather Prediction Center released its monthly update of the ongoing solar cycle sunspot activity, covering February 2012. Though I am slightly late in posting it, as I do every month, you can now see the full graph below the fold. I have also created a close-up of the graph’s relevant area, shown on the left, because it is hard to decipher what is happening on the full graph.

Since the Sun began it ramp up to solar maximum back in 2009, the pattern has been consistent, two steps forward, one step back. First there are several months in a row in which the number of sunspots show a steep rise, followed immediately by several months in which the sunspot numbers decline just as steeply, though by not as much. All told, since 2009 we have seen this pattern repeat four times.

February’s numbers have continued that pattern.

Playing hardball

9:23 am

The director of Russia’s manned program told the press today that the Russians do not have that a signed contract with NASA to fly astronauts to ISS after 2015, despite NASA’s announcement that such an agreement exists.

If true, NASA’s management has committed a very serious error which will cost the U.S. a great deal of money in the coming years, especially if there are significant delays in getting the new commercial companies online to provide the U.S. an American capability for ferrying humans to orbit.

A Thank You From Japan

7:01 am

One year ago today Japan was hit with one of the most powerful earthquakes in recorded history, followed almost immediately by one of the most powerful tsunamis in recorded history. Since then, that nation and its people have done an incredible job recovering from that disaster, proving once again that there really is no limit to what humans can do.

The video below is their thank you to the rest of the world for the help and support brought to Japan by people everywhere. As they say, “Arigato.”

I say, bless you all for never giving up.

The spaceship companies in Mohave are hiring

7:44 am

Want a job building spaceships? The spaceship companies in Mohave are hiring.

There are several hundred open positions in Mojave as companies such as the Spaceship Company, XCOR and Scaled Composites begin to ramp up operations. “It’s ironic that we’re having a recruitment problem in Mojave,” said Stu Witt, CEO and general manager of the Mojave Air and Space Port. He added that this is a good problem to have.

A new bill in Congress would clarify the rights of 1960s astronauts to the space-flown artifacts they took home after their flight.

A new bill in Congress would clarify the rights of 1960s astronauts to the space-flown artifacts they took home after their flight.

What I don’t like about this is that it is so specific, only protecting the rights of the astronauts from the 1960s. Why not extend these rights to all those who fly on NASA missions?

In the Oklahoma primary last week Barack Obama only garnered 57% of the vote, and actually lost in 15 counties, 12 to a pro-life activist and 3 to a state’s Democratic senate candidate from 2010.

What does this tell us? In the Oklahoma primary last week Barack Obama only garnered 57% of the vote, and actually lost in 15 counties, 12 to a pro-life activist and 3 to a state’s Democratic senate candidate from 2010.

What it tells me is that there is a much stronger upwelling of hostility to Obama than anyone in the political world right now imagines. Granted, this is Oklahoma, a very conservative state. Nonetheless, for a sitting President to do this poorly among voters in his own party does not bode well for that President — or his party — come November.

Two Democratic senators have introduced legislation that would repeal the indefinite detention of Americans authorized by the National Defense Authorization Act of 2012 that was passed in November.

Good for them: Two Democratic senators have introduced legislation that would repeal the indefinite detention of Americans authorized by the National Defense Authorization Act of 2012 that was passed in November.

My only complaint is this: Why did these same two senators, along with 81 other senators and 283 House members vote for this unconstitutional obscenity in the first place?

The Senate’s tea party caucus has introduced a budget plan aimed at balancing the federal budget by 2017.

1:42 pm

The Senate’s tea party caucus yesterday proposed a budget plan aimed at balancing the federal budget by 2017.

The news article gives a broad outline of the plan, including some basic changes to several entitlement programs, a freezing of government spending at 2008 levels, and the elimination of four government agencies and the privatization of the TSA. A detailed look will probably find that some of these proposals are poorly thought out or impractical. However, at least these senators are proposing something, unlike the Democrats, who in the Senate have not even introduced a budget for more than three years.

smaller planets are preferentially found in low-eccentricity orbits.

9:24 am

More Kepler results: From the abstract of a preprint paper published today on the Los Alamos astro-ph website:

The mean eccentricity of the Kepler candidates decreases with decreasing planet size indicating that smaller planets are preferentially found in low-eccentricity orbits.

In other words, the smaller a planet is, the more likely its orbit will be circular like the Earth’s. This result is encouraging news for the search for life on other worlds. Before Kepler, astronomers had found that the orbits of most exoplanets were far more eccentric than the orbits of the planets in our solar system, a condition that scientists thought was unfriendly for the development of life. These new results counter that conclusion. The orbits of the planets in our solar system might not be as unusual as first thought.
