The first solar eclipse to cross the continental United States in two decades will occur on May 20.

7:09 pm

Set your calendar: The first solar eclipse to cross the continental United States in two decades will occur on May 20.

An annular solar eclipse occurs when the moon passes between the earth and sun, but the lunar disk does not completely block out the sun and instead leaves a “ring of fire” visible around the moon at the point of maximum eclipse. Most anyone west of the Mississippi will see a partial eclipse, but the real treat will be for those located in the 200-mile wide path of the eclipse which will trek east from the California / Oregon border through Nevada, Utah, Arizona, New Mexico, and finally set below the horizon in west Texas.

Remember, you will need good eye protection if you choose to look.

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.

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

ATK today announced that it is building its own manned capsule for its Liberty solid rocket.

6:58 pm

The competition continues to heat up: ATK today announced that it is building its own manned capsule for its Liberty launch system.

The capsule’s first two flights are scheduled in 2014, both abort tests, followed in 2015 by an orbital flight and, finally, a crewed orbital flight. The spacecraft is designed for ten flights each, and ATK plans to build a minimum of four capsules. All flights will be launched by the Liberty launcher, and ATK is not actively exploring adapting the capsule for other [launch vehicles].

Liberty is based on the upgraded shuttle solid rocket boosters that were developed for the Ares rocket, now cancelled.

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.

An Indian tribe has sued and three researchers have countersued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.

Fighting over bones: An Indian tribe has sued and three researchers have counter-sued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.

Not surprisingly, the problem here stems from a poorly written federal law amended by a bureaucratic rule in 2010 that gives any Indian tribe control over any ancient human bones found in the U.S., even if those bones come from a human that lived long before the tribe even existed.

A trend, not a fluke: Indiana Republicans dump Senator Richard Lugar for a tea party favorite.

A trend, not a fluke: Indiana Republicans have dumped incumbent Senator Richard Lugar for a tea party favorite.

In related news, a prison inmate has gotten the highest percentage of votes, 40 percent, of any candidate in any previous state primary against Barack Obama.

Washington politicians had better stop ignoring the fiscal concerns of the tea party. The federal budget has got to be brought under control.

One astronomer has found that the habitable zone around some smaller stars is smaller than first calculated because of tidal heating.

One astronomer has found that the inner edge of the habitable zone around some dwarf stars is smaller than first calculated because tidal forces overheat planets close to the star.

Then again, this heating might expand the habitable zone in other directions. Stars might overheat when close to the star, but get a boost of needed heat when they would normally be too far away.

Richard Rogers – Edelweiss

6:01 pm

An evening pause: From The Sound of Music (1965). The context: The Nazis have taken over Austria, and plan to arrest Captain Georg Ludwig von Trapp and his family at the end of this concert. This lovely song, Edelweiss, is initially sung by von Trapp as a farewell to his nation. As the song unfolds, however, it becomes instead a song of defiance against the Nazis, by the von Trapps and the audience.

Always, always, we must stand for freedom.

Astronomers now believe that Type 1a supernovae — used to discover dark energy — can be produced in two different ways.

9:52 am

The uncertainty of science: Astronomers now believe that Type 1a supernovae — used to discover dark energy — can be produced in two different ways.

Type Ia supernovae are known to originate from white dwarfs – the dense cores of dead stars. White dwarfs are also called degenerate stars because they’re supported by quantum degeneracy pressure. In the single-degenerate model for a supernova, a white dwarf gathers material from a companion star until it reaches a tipping point where a runaway nuclear reaction begins and the star explodes. In the double-degenerate model, two white dwarfs merge and explode. Single-degenerate systems should have gas from the companion star around the supernova, while the double-degenerate systems will lack that gas.

For astronomers, this possibility raises several conflicting questions. If two different causes produce Type 1a supernovae, could their measurement of dark energy be suspect? And if not, why is it that these two different causes produce supernovae explosions that look so much alike?

Massachusetts state officials are restricting the kinds of foods that can be sold at bake sales.

We’re here to help you: Massachusetts state officials are restricting the kinds of foods that can be sold at bake sales.

Bake sales, the calorie-laden standby cash-strapped classrooms, PTAs and booster clubs rely on, will be outlawed from public schools as of Aug. 1 as part of new no-nonsense nutrition standards, forcing fundraisers back to the blackboard to cook up alternative ways to raise money for kids.

Scientists have found that a solar Grand Minimum 2800 years ago might have caused a period of cooling in Europe

Scientists have found that a solar Grand Minimum 2800 years ago might have caused a period of cooling in Europe.

The evidence for this link is at this moment slim, based upon a single data point from a lake in Germany. Nonetheless, it is further evidence that the Sun’s production of sunspots is more important to global climate than climate scientists had previously believed.
