Another planet has been found in the habitable zone

9:06 am

Planets without end: Another planet has been found in the habitable zone.

Gliese 163c could have a size between 1.8 to 2.4 Earth radii, depending if it is composed mostly of rock or water, respectively. It receives on average 40% more light from its parent star than Earth from the Sun, making it hotter. In comparison, Venus receives 90% more light from the Sun than Earth. We do not know the properties of the atmosphere of Gliese 163c but, if we assume that it is a scaled up version of Earth’s atmosphere, then its surface temperature might be around 60°C [140°F]. Most complex life on Earth (plants, animals, and even humans) are not able to survive at temperatures above 50°C [122°F], however, plenty of extremophilic microbial life forms can thrive at those temperatures or higher.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

A new study of the Earth’s past climates has revealed that during warming periods the number of species multiplied.

The article spends a lot of time explaining that just because global warming in the past was beneficial for life does not mean that global warming today will be a good thing. Or to put it another way: “Absolutely not! We mustn’t think that! It can’t be! Never!!!! My fingers are in my ears! La-la-la-la-la-la-la-la-la-la!”

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 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.

The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.

The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.

It appears that the lab has been researching the useful properties of these nanocrystals, which is a good thing. However, I can’t help wondering why they are now building a production plant. Shouldn’t this be left to the private sector? What business is it of the Forest Service to be a producer of this product? It could be that the plant is aimed not at production but at figuring out how to make it affordable and practical, a goal that might make sense for a government agency to pursue. If not, however, it seems inappropriate for a government agency to use taxpayer dollars to run a facility aimed at selling a product to the private sector.

The article, as well as the lab’s webpage, do not make this clear.

The head of the Russian space center that built the upper stage that failed on two recent Proton launches has been fired.

The head of the Russian space center that built the upper stage that failed on two recent Proton launches has been fired.

Putin’s action here suggests the Russians are taking these problems seriously. especially with the looming competition from SpaceX. At the same time, the boss doesn’t actually build anything, and firing him won’t fix anything if there aren’t also changes on the factory floor.

“Healthy Ridicule.”

5:34 pm

“Healthy ridicule.”

It is healthy for America that the president be criticized and even mocked. Deference to a Dear Leader has no place in a democracy. It’s healthy for race relations, too, that he be judged on his record rather than held to a lower standard in the name of racial progress. When a black politician is treated just like any other politician, that’s genuine progress.

And then there’s this:

Obama’s journalistic supporters live in a bizarre alternate reality in which a politician’s actual words mean nothing. When the president says something foolish and offensive, he didn’t say that. Meanwhile every comment from a Republican can be translated, through a process of free association, to: “We don’t like black people.”

Taranto’s second point above suggests to me that there are a lot of people on the left whose recent behavior is making them ripe targets for some very healthy ridicule.

New Horizons — on its way to Pluto — will take a look at a different Kuiper Belt object in January 2015.

New Horizons — on its way to Pluto — will take a look at a different Kuiper Belt object in January 2015.

The encounter will take place at a range of about 75 million km, a distance somewhat subject to change depending on how the probe makes its course correction. At such a great distance, New Horizons will not be able to discern features on the surface of the KBO, nor will it be able to make spectroscopic observations to try to determine the composition of the surface material.

However, New Horizons will be in an excellent position to look for small, close-in moons around the object. It will also be in a position to observe the object’s phase curve, which is a measure of how the reflectivity of the surface changes as a function of viewing angle. This will reveal a great deal about the fluffiness of the surface material (note – fluffiness is a technical term meaning, roughly, “the opposite of dense”). These two observations cannot be made from Earth, even with the most powerful telescopes available.

“While partisan activists tune in when their team’s big show is on the air, most unaffiliated voters view the conventions as a waste of time and money.”

Scott Rasmussen: “While partisan activists tune in when their team’s big show is on the air, most unaffiliated voters view the conventions as a waste of time and money.”

Read the whole thing. His analysis of the meaninglessness of the political conventions to the ordinary voter is right on the money. More significant, his willingness to separate himself from the political atmosphere of Washington and try to empathize with those ordinary voters illustrates clearly why he is today’s most reliable pollster.

Police once again raid the wrong house and kill a pet dog.

Police once again raid the wrong house and kill a pet dog.

What is it with these damn cops and their eagerness to kill dogs? There is simply no justification for this. First, the dog is someone else’s property. They have no right to destroy it, even if they do have a warrant. Second, there are many better and more humane ways to pacify a dog than killing it. With all their training, paid for by tax dollars, you’d think someone might tell them this.

Scientists have determined that the shape of a beer glass can influence how much beer you drink.

6:40 pm

Science marches on! Scientists have determined that the shape of a beer glass can influence how much beer you drink.

After watching video of both sessions and recording how much time it took for the drinkers to finish their beer or sodas, Attwood’s team found that one group consistently drank much faster than the others: the group drinking a full glass of lager out of curved flute glasses. In a paper published this month in PLoS ONE, the team reports that whereas the group with straight glasses nursed their 354 milliliters of lager for about 13 minutes, the group with the same amount of beer served in curved glasses finished in less than 8 minutes, drinking alcohol almost as quickly as the soda-drinkers guzzled their pop. However, the researchers observed no differences between people drinking 177 milliliters of beer out of straight versus fluted glasses.

The last sentence reveals the large amount of uncertainty that surrounds this important research.

The makers of a documentary critical of the Occupy Wall Street movement have received threats of violence against themselves and their families

5:58 pm

Leftwing civility: The makers of a documentary critical of the Occupy Wall Street movement have received threats of violence against themselves and their families in advance of the film’s premiere.

“We’ll be legitimately raping Brandon Darby and Lee Stranahan for the next several days while they are tied up with the movie premier at the RNC,” reads an email from occupyaunmasked2012@gmail.com. The email includes Darby’s and Stranahan’s cell phone numbers.

One tweet reads, “While @Shanahan is in Tampa this week, should Texas rapists be told where to find his wife since he supports the rape of everyone else?”

“My wife is home with our four kids and freaked out,” Stranahan told The Hollywood Reporter. “She’s sick to her stomach.” Stranahan and Darby each said their home addresses have been published online by those who claim sympathy to OWS.

Two astronauts completed an eight hour spacewalk today, extended because of problems with several stuck bolts.

Two astronauts on ISS completed an eight hour spacewalk today, extended because of problems with several stuck bolts.

Williams and Hoshide initially progressed well through their tasks, but the astronauts struggled with difficult bolts when removing a faulty power box from the exterior of the space station, and then again when replacing the defunct unit with a new spare.

More information here. In the end they were forced to leave the replacement unit only temporarily attached because the bolts would simply not screw in. It was thought there might be debris in the screw holes.
