Meanwhile, in the cosmic shooting gallery…

From Asteroid Apocalypse at the Daily Beast:

The city of Chelyabinsk in Russia bore the brunt of the celestial fireworks. A piece of rock, about 50 feet across and weighing more than 7,000 tons, came crashing to Earth. Traveling at a blinding speed of over 40,000 miles per hour, it created a sonic boom and shock wave that shattered windows across the city: 1,200 people were injured, mainly by the flying pieces of glass, and 52 were hospitalized, 2 of them in serious condition. Chelyabinsk, once known as one of the most polluted places in the world due to its storage of nuclear waste, will now be known as “meteor city.”

The asteroid packed a huge punch, the power of 20 Hiroshima bombs. It was a “city buster,” capable of flattening a modern metropolis and reducing it to rubble. It was a miracle that the asteroid exploded roughly 10 to 15 miles above ground: had there been a ground burst, it would have caused tens of thousands of casualties. If that asteroid had hit just a few seconds later, it would have created a tragedy on Earth.

…Lurking in space are asteroids even bigger than the city busters—to wit, “nation busters” big enough to destroy Germany or England. The most dangerous one is called Apophis, which is 1,000 feet across and will come dangerously close to Earth in 2029 and again in 2036. The most recent calculations show that Apophis will barely miss Earth in 2029, but will actually graze our atmosphere. But because of the uncertainty of its path as it whizzes past, there is a small possibility that its orbit may be perturbed so it might actually hit Earth in 2036. NASA scientists are reasonably confident it will still miss Earth in 2036, but the head of the Russian space agency takes the threat of a collision seriously, stating that we have to prepare for the worst. If Apophis hits Earth, it would have the force of approximately 20,000 Hiroshima bombs.

Read on for more about this frightening subject that is also one of the most compelling arguments for a strong space program that I know of.

Steve Jurvetson took this shot at the massive Meteor Crater in Arizona. Click that link for info from NASA and check out Hiking to the bottom of Meteor Crater for more shots from Steve’s journey! His Quarries, Mines & Holes slideshow is really cool too!

Just looked at Meteor Crater and wondered how big it was. Wikipedia says that Meteor Crater aka Barringer Crater got its names from the nearby town Meteor and Daniel Barringer. From there I wandered off to read about Barringer’s actions in the early 20th century and the list of the world’s largest impact craters (this one’s just a little guy!) and the curiously tiny impact craters of the United States.

Guns, etc.

Rolling Stone columnist Matt Taibbi is hands down my favorite pundit out there right now. In his latest column, Republicans Have Their Worst Week Ever, he writes that watching the GOP over the past week has been like watching the Three Stooges try to perform a liver transplant on roller skates.

Consider: Conservative action group Political Media launches Gun Appreciation Day and got 50 million people (which is a not insignificant 1.6%) to sign a whereas-packed petition that concludes with the money shot of:

Therefore, We the Undersigned petition the United States Government to cease and desist all efforts to disarm or short-arm the American people by limiting and disparaging the Second Amendment or rendering it a dead letter through federal legislation, interpretation and regulation.

I don’t even know what the means legally, except that maybe if you try to short arm them you’ll end up in the dead letter office.

But even before their excellent idea gets out of the gate, it stalls out, as obnoxious reporters check the list of “Gun Appreciation Day” sponsors and find that the “American Third Position,” a group that purports to represent the “unique political interests of White Americans,” is one of the event’s sponsors.

So now, Political Media has not only decided to hold its Gun Appreciation Event on a holiday meant to celebrate the life of a black leader who was a symbol of nonviolent protest and who was killed by a white man with a gun, it’s done so with the financial help of some yahoo white supremacist group. But this doesn’t derail the whole thing, as it’s of course just an innocent mistake. Political Media kicks “Third Position” out and appropriately issues a statement, saying, “We have removed the group and reiterate this event is not about racial politics, it is about gun politics.”

So far, so good, right? Well, then they go and actually hold their “Gun Appreciation Day” rallies all over the country, on Martin Luther King Day. And what happens? Five people get accidentally shot!

Definitely read on for more examples of Herculean idiocy including the suggestion that the film Django Unchained makes the argument for gun rights because there wouldn’t have been slavery if slaves had gun rights. Brilliant!

Here’s Matt on Totally Biased w Kamau Bell. A great interview on a great show, and I extra-heartily encourage you to watch Matt Taibbi & Chrystia Freeland on Bill Moyers show that explores income inequality, which is at its greatest in recorded history right now. Come on, watch it.

Kevin Dooley provided the photo and the title of this post, Guns, etc. Kevin is a wonderful photographer who shares his photos via Creative Commons, about which he writes (in part):

If you don’t care about making money from your images (at least at this stage of your life) but want them broadly seen, then you have to label your photos as Creative Commons and get on the open source photography bandwagon.

Habitable Exoplanets

NASA’s Kepler Mission is a spacecraft observatory that scans a single large area of the sky in the constellations Cygnus and Lyra. It simultaneously measure variations in the brightness of over 100,000 stars every half hour, searching for the half hour to half a day “winks” in light output that happen when a planet transits, aka passes in front of its star. Transits are only seen when the star’s planetary system is nearly perfectly aligned with our line of sight. For a planet in an Earth-size orbit, the chance of it being aligned to produce a transit is less than 1%, and the change in light akin to the dimming of a flea crawling across a car’s headlight and viewed from several miles away. Check the videos for more of an idea of how this observatory works.

It was named in honor of Johannes Kepler, who described the motions of planets about the Sun in a precisely predictable manner. Since its launch in 2009, Kepler has confirmed over 2000 planets. If you’d like to try your hand at sifting through the Kepler data, check out planethunters.org. Also check out the Kepler Mission on Facebook, where I learned that William Borucki, science principal investigator for the Kepler mission, received the National Academy of Sciences 2013 Henry Draper Medal for founding concept and visionary leadership of the project.

I’m voting for Barack Obama

On Tuesday I am going vote once again for Barack Obama.

He’s one of the rare few who have become more than a President, a true Commander in Chief.

Did he magically solve all our problems and reach across the aisle to convert recalcitrant foes to allies? No, he did not.

Did he act decisively and wisely to stave off what could easily have been the 2nd Great Depression, exercise a calm and firm hand in the face of a host of foreign policy challenges, and accomplish far more than you would expect given an opposition who decided that the purity of their party was more important than the health of our nation. Yes he did*.

We’re standing at the the doorstep of the future and more than rising water and raging weather are coming to our door. I for one want a proven and tested leader who has demonstrated honesty on a constant vision rather than an opportunistic and shadowy operator who stands wherever the people he’s talking to want him to stand.

*For those who feel that he’s done nothing, I give you whatthefuckhasobamadonesofar.com.

 

Driven by the wind

Wind Map says:

An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future.

This map shows you the delicate tracery of wind flowing over the US.

It’s a windy day all across the nation today. The U.S. has really increased wind power generation over the last decade. Wikipedia sez wind is over 3% of our total power mix now. While we lag Denmark  at 26%, Portugal (17%), Spain (15%) or Ireland at 14%, with almost 50,000 megawatts of capacity, we are second in the world to China’s 62,733 MW.

This photo (Wind farm and greenhouse gas farm, together) is by Kevin Dooley, a leader in Creative Commons photography. See it bigger in his 100 most interesting slideshow. Kevin writes:

Hey look! Here on Interstate 10 near Palm Springs, California, we can see a wind farm that is saving the planet and a greenhouse gas farm that is destroying it.

What are we going to farm in our future? Millennia dead, dead end fossils or the invisible and ancient wind?

Looking up with NASA

I told someone about the amazement of the stars over Mt. Shasta and found this photo. I figured I probably better look up something about the Milky Way to justify it. What I found was NASA’s current missions page.

It includes a surprising number of diverse “missions” – satellites, probes and expeditions – that I found to be very reassuring and in several cases, very timely and each delivering some very cool data!

I hope that we can please continue to find funding as a nation explore our universe … I’m sure that we can look at our priorities or maybe even some of us can afford a little more in taxes to pay for this.

Let me also say: “Well done NASA, you definitely know how to name a mission.”

The photo is Mt Shasta by NASA. It was posted by Viktor Reinhart, and he has a bunch more shots in his Mt. Shasta slideshow.
