ALMA detects a solar flare on Mira 420 light years away

9:17 am

Mira A and Mira B

The just completed ALMA (Atacama Large Millimeter/submillimeter Array), a collection of 66 antennas located in Chile, has snapped a picture of the variable star Mira with its companion star, detecting details on the primary’s surface, including evidence of a solar flare.

Mira is a star with a mass like our Sun’s, but near the end of its life having evolved into a red giant that is shedding its outer layers. Being able to track its behavior with this kind of detail will allow astronomers to better hone their theories about the life and death of stars, including our own.

Another major image release from Rosetta

9:34 am

Time for many cool images! The Rosetta science team has just released to the public another batch of images from its navigational camera.

The 1776 images cover the period between 23 September and 21 November 2014, corresponding to Rosetta’s close study of the comet down to distances of just 10 km from the comet centre – 8 km from the surface – and the images taken during and immediately following the landing of Philae on the comet.

You can browse through them at your leisure, making your own discoveries if you have a sharp eye and know something about planetary geology.

A solar system like our own, but when it was a baby

9:28 am

Astronomers have discovered a very young 15 million year old star only 360 light years away that has a debris disk about the size of our solar system’s Kuiper Belt.

The ring is about the same distance from its parent star as the Kuiper belt is from the Sun, and receives roughly the same amount of light. Its blue-grey colour hints that it could consist of ices and rocky silicates such as those found in the Kuiper belt, says lead author Thayne Currie, an astronomer at the Subaru Telescope in Hawaii, which is run by the National Astronomical Observatory of Japan. “This is absolutely the closest example we have of a young Kuiper belt,” he says.

The best part of this discovery however might be how it was made, by using a new instrument on the ground-based Gemini telescope on Mauna Kea in Hawaii.

The instrument, which is part of the Gemini South telescope in Chile, uses a disk called a coronagraph to blot out the glare of bright stars. That allows it to take multi-wavelength pictures of faint, orbiting planets and debris disks around stars, by recording near-infrared light from the parent star as it scatters off the debris. The researchers discovered the disk around HD 115600 fewer than 6 months after the GPI began operation. A similar instrument, known as SPHERE, began operating in May 2014 on the European Southern Observatory’s Very Large Telescope in Chile and has also begun to make discoveries.

Assuming protesters don’t force Gemini to close, we should be getting a lot more exoplanetary discoveries from it in the coming years.

Russian rocket engines ready for shipment to U.S.

9:14 am

The competition heats up: An engine that Russia has developed for its Angara rocket has now been tested and is ready for shipment to the U.S. for use in the first stage of Orbital ATK’s Antares rocket.

This new engine will replace the refurbished Soviet-era engines Antares had been using previously that had caused the October launch failure. Note also that since Antares is not a military rocket, it does not fall under the Congressional ban for Russian engines that limits their use on ULA’s Atlas 5 rocket. As the article notes,

On Jan. 16, 2015, RKK Energia, parent company of NPO Energomash, announced that it had reached an agreement with the American company Orbital Sciences Corporation, OSC, on the export of RD-181 engines for the first stage of the Antares rocket, thus replacing the NK-33 engines previously used on the launcher. The contract, worth around $1 billion, was actually signed and ratified by the Russian government in December 2014. According to the document, a total of 60 RD-181 engines would be delivered to OSC beginning in June 2015.

This deal means that Antares will likely be back in business soon, though it will still be dependent on Russian-built equipment, which carries its own risks. It also means that Orbital ATK will not be able to sell Antares to the U.S. military, limiting its marketability.

It looks like the Moon!

9:03 am

craters on Ceres

Cool image time! Dawn has now swooped down to 3,200 miles, and provided a very nice image of the cratered surface of Ceres. Though it does appear to resemble the Moon, there are some differences that come to mind if you take a close look at the full resolution image. The surface appears smoother. All of the craters appear worn or eroded or less rugged. Also, there are no mountains. The terrain resembles the Moon’s lowlands or maria, but more so.

Note that the region in this picture is tantalizingly close to the double bright spot, but does not include it. Because Dawn is still easing its way into its first survey orbit of 2,700 miles elevation, it only takes pictures when it stops firing its ion engine, which it is doing almost all the time to get where it wants to be. Thus, they apparently only had time for this image.

The spacecraft enters its mapping orbit on June 3. Expect some cool images, including the first good images of the double bright spots, shortly thereafter.

A journalist and filmmaking team fake a study and the press buys it

10:54 pm

The uncertainty of science journalism: How a science journalist and two documentary filmmakers fooled millions (and many science journalists) into thinking that eating chocolate will help you lose weight.

My colleagues and I recruited actual human subjects in Germany. We ran an actual clinical trial, with subjects randomly assigned to different diet regimes. And the statistically significant benefits of chocolate that we reported are based on the actual data. It was, in fact, a fairly typical study for the field of diet research. Which is to say: It was terrible science. The results are meaningless, and the health claims that the media blasted out to millions of people around the world are utterly unfounded.

He then describes step by step how they did it. They even got their “research” published in a journal that claimed it did peer review but did not change one word of their submitted manuscript and published it less than two weeks after submission and the receipt of their money (science journals traditionally require authors to pay them for the honor of publication). In the end,

We landed big fish before we even knew they were biting. Bild rushed their story out—”Those who eat chocolate stay slim!”—without contacting me at all. Soon we were in the Daily Star, the Irish Examiner, Cosmopolitan’s German website, the Times of India, both the German and Indian site of the Huffington Post, and even television news in Texas and an Australian morning talk show.

The American women’s magazine Shape also fell for the fraud.

To me, the main reason the fraud worked was because none of the journalists involved ever bothered to actually read the science paper. They saw the press release, thought the story was cool, and simply rewrote the release. This is what happens repeatedly in the science field, and is why so much crap about climate science gets published. Too many reporters accept verbatim the claims of the scientists, doing no research to check the facts on which those claims were based.

I should mention also that John Bohannon, the man who played the scientist in this prank, also ran a sting operation against peer review journals in October 2013, creating a bogus paper and getting 157 journals to accept it for publication.

“These are the brownshirts of our time.”

Link here.

Read it. Though the author describes an event that happened in 2003, it shows us ugly circumstances that have now become quite common, because as she says, “the ‘good’ people did nothing to disperse the hostility.” And unless we do something about it now — stand up to these fascist thugs who hide behind nice-sounding ideologies — what is happening today in the worst places in the Middle East is only showing us what things will be like here in another dozen years.

Russian rocket now garden furniture in England

5:36 pm

A British businessman has purchased a discarded Russian rocket and installed it in his garden as decoration.

Almost 40ft long and weighing five tonne, the rocket was first flown in 1991 after being built by the Russians in collaboration with NASA at a cost $10 million. For ten years it held the record for the fastest ever made-made machine before it was jettisoned as archaic.

Somehow it ended up at a car auction at South Marston where it was spotted by Mr Sweet while checking out vintage motors. Mr Sweet, who runs the Cirencester-based computer company Zycko, said: “I saw it for sale at a car auction and decided to buy it, not really knowing what I was going to do with it.”

I am curious how the rocket had ended up being owned and offered for sale by a UK company that “specializes in car restorations.” I also wonder if this might be a major new profit center for the struggling Russian rocket industry.

X-37B orbit uncovered

5:27 pm

Space hobbyists have pinpointed the classified initial orbit of the recently launched X-37B.

Observers this week spotted the craft flying overhead in a 194 by 202 mile orbit (312 X 325 km), tilted 38 degrees relative to the equator. That perch is lower than previous X-37B missions and the inclination is lower, too.

“OTV 4 entered the lowest initial altitude of the program,” said Ted Molczan, a respected satellite observing hobbyist. “The ground track nearly repeats every 2 days. Frequently repeating ground tracks have been a common feature of the program. This could be an indication of a surveillance mission, or it may offer some operational advantage I have yet to figure out.”

Not much else has as yet been uncovered.

New Images of Pluto from New Horizons

5:20 pm

Pluto in mid-May

Cool image time! New images taken by New Horizons of Pluto in mid-May have begun showing faint details of the planet’s surface.

“These new images show us that Pluto’s differing faces are each distinct; likely hinting at what may be very complex surface geology or variations in surface composition from place to place,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado. “These images also continue to support the hypothesis that Pluto has a polar cap whose extent varies with longitude; we’ll be able to make a definitive determination of the polar bright region’s iciness when we get compositional spectroscopy of that region in July.”

These images also suggest vaguely that Pluto might not be entire spherical, but I wouldn’t put much money on that speculation. We will know for sure in just a few more weeks.

NSF to help fund the development of implantable antennas

1:47 pm

What could possibly go wrong? The National Science Foundation (NSF) is providing funding for the development of an implantable antenna for health care, including the possibility for “long-term patient monitoring.”

The project is being financed in collaboration with the National Research Foundation of Korea to create a high frequency antenna that can be permanently implanted under a person’s skin. “Antennas operating near or inside the human body are important for a number of applications, including healthcare,” a grant for the project said. “Implantable medical devices such as cardiac pacemakers and retinal implants are a growing feature of modern healthcare, and implantable antennas for these devices are necessary to monitor battery level and device health, to upload and download data used in patient monitoring, and more.”

The grant said that an implantable device could be used for “long-term patient monitoring” and “biometric tracking,” or using technology to verify a person’s identity.

Without any doubt there are many very useful applications for such an implantable device. Monitoring battery life on pacemakers is an obvious one. There will be a problem, however, if anyone but the patient can do the monitoring. I can see too many possible misuses occurring should it be in anyone else’s hands. At a minimum, there are big privacy concerns.

Hubble films of movie of a jet firing from a black hole

12:38 pm

Cool image time! Using images taken by the Hubble Space Telescope over the past two decades astronomers have assembled a movie of the motion of blobs, ejected by a jet from a supermassive black hole at the center of a galaxy.

The jet from NGC 3862 has a string-of-pearls structure of glowing knots of material. Taking advantage of Hubble’s sharp resolution and long-term optical stability, Eileen Meyer of the Space Telescope Science Institute (STScI) in Baltimore, Maryland, matched archival Hubble images with a new, deep image taken in 2014 to better understand jet motions. Meyer was surprised to see a fast knot with an apparent speed of seven times the speed of light catch up with the end of a slower moving, but still superluminal, knot along the string. The resulting “shock collision” caused the merging blobs to brighten significantly.

The movie is below the fold.

Secret Service tries to steal $115K from a business couple

11:23 am

Theft by government: The Secret Service seized a business couple’s bank account with no warning merely because they had withdrawn just under $10,000 several times.

After months of litigation against the United States government, Assistant U.S. Attorney Stephen West moved to dismiss the case earlier this month, meaning the Bednars will get their money back. However, the government refused to cover the Bednar’s $25,000 in legal fees, which the couple is entitled to under the Civil Asset Forfeiture Reform Act. Though the fight to get their $115,000 back is now over, the family is continuing to push to have their expenses covered. [emphasis mine]

First the government tries to steal their money. Now, it is trying to ignore the law by not paying their legal fees, even though the law requires it to.

But hey, we all know the best solution to all our problems is the government!

Obamacare overhead eats 22% of all health care costs

11:04 am

Finding out what’s in it: A whopping $270 billion, 22% of all health costs, is being spent on administration and bureaucracy under Obamacare.

The experts at the link who have revealed these numbers are hostile to private industry and are instead advocates for nationalizing healthcare. They claim it is private industry that causes these high costs. I say it is the complexity and Kafkaesque regulations that Obamacare imposes that make healthcare difficult to administer. I say the solution would be simplify things by repealing Obamacare entirely.

Instead, the Democrats want to expand Obamacare. The Republican leadership in Congress meanwhile suggests chipping at it piecemeal, which will only increase its complexity and make things more difficult to administer.

With leaders like this we are certainly doomed.

Criminal charges against Russian workers who caused Proton failure

10:50 am

The three Russian technicians and their supervisor whose sloppy work caused the spectacular 2013 crash of a Proton rocket immediately after launch have now been indicted on criminal charges and will face trial.

According to investigators, Grishin, Nikolayev and Gudkova in 2011 were tasked with installing the angular rate sensors on the Proton rocket that are responsible for yaw control. “As a result of their violation of technical discipline envisaged by engineering and technological documentation, these sensors were installed incorrectly / at 180 degrees from their correct position/,” Markin said.

The installation error accounted for the vehicle’s wild trajectory, causing its crash and destruction. During the investigation, Grishin and Nikolayev partly admitted their guilt in committing the crime, he said.

In his turn, Nasibulin guided by the fact that over a long time no violations had been found during the installation process and also amid the job cuts withdrew the control operation from a respective list. He did not monitor the process and the sensors were installed without the due control.

Note that they didn’t sabotage anything intentionally. They only did bad work. In the U.S. such incompetence would certainly get them fired, but no one would dream of prosecuting them under these circumstances. It appears that Putin’s government has decided to make them scapegoats and an example to everyone else: Do your work right or else!

Along these lines, Russian government officials have also indicated they are considering imposing fines on manufacturers for any future failures or delays.

Both the criminal indictments and the fines would surely work to prevent further disasters. They will also work very effectively in preventing any risk-taking or innovation from anyone. Who wants to build something new and untested if there is a strong possibility its failure will get you in prison?

Do not expect much creativity from the Russian aerospace industry in the coming years.

Hawaii’s governor imposes new deal for Mauna Kea

10:29 am

In his effort to appease the protesters hostile to building the Thirty Meter Telescope (TMT) on Mauna Kea, Hawaii’s Democratic governor has thrown out the decades-old agreement that had guided telescope construction there and has instead imposed a new deal, which will allow for TMT but will force astronomers to remove one quarter of the other telescopes on the mountain.

Astronomers have always honored the original agreement, allowing the construction of no more than 13 telescopes on the mountain. For example, to build TMT the Caltech Submillimeter Observatory was to be removed this year. Now they will have to remove some additional telescopes that had been built with the understanding that they could remain there, based on the original agreement.

The governor’s plan will also limit access to the mountain by non-natives, and require visitors to receive “cultural training”, likely a session explaining the sacredness of the native religion and how it must be obeyed at all times.

To my mind this new deal is another indication of the slow retreat of western civilization in the U.S. Once again our ability to push the unknown will be limited in favor of fostering the superiority of one ethnic group over another.

Solar sail experiment stymied by software crash

10:14 pm

The Planetary Society’s LightSail solar sail test mission, launched as a secondary payload on last week’s Atlas 5 X-37B launch, has fallen silent because of a software problem.

The communications problem occurred before the mission could achieve its main engineering goal of testing the deployment of the solar sail. They still hope to regain communications, but time is limited as the cubesat is in a low orbit that will decade relatively quickly.

NOAA caught tampering with temperature data again

9:51 pm

A close look at NOAA’s temperature data for Maine has revealed that sometime between 2013 and 2015 the data was drastically adjusted to cool the past and warm the present.

No explanations for these changes has been offered. For some years they cooled the past as much as 4 degrees Fahrenheit, an adjustment that cannot be justified under any scientific method. As asked at the link, “Would someone please try to explain why this isn’t the biggest scandal in the history of science?”

Democrats propose more Obamacare to solve problems caused by Obamacare

3:22 pm

Link here. Read it all, but here is a good quote to get you started:

The problem is that the deductibles on many Americans’ health insurance policies have shot up so high that as a practical matter they can’t afford care. If a couple had a deductible of, say, $500 in the past, and it’s now $3,000, that couple has to spend a lot of money out-of-pocket before reaping the benefits of coverage. And the higher the deductible, the more likely a person is going to skip some sort of needed treatment or medicine because he or she can’t afford the up-front costs. “About a quarter of all non-elderly Americans with private insurance coverage do not have sufficient liquid assets to pay even a mid-range deductible, which at today’s rates would be $1,200 for single coverage and $2,400 for family coverage,” the Wall Street Journal reported in March.

So now, many of the same groups that agitated for Obamacare are agitating for new government spending or tighter controls on the insurance industry and businesses to “solve” the problem. But perhaps the first question to ask is: How did those deductibles get so high in the first place?

The answer is Obamacare.

Bluntly, almost all the high costs and deductibles we see now in health insurance and healthcare that have appeared in the last five years have occurred because they were specifically mandated by Obamacare. So of course, according to the warped logic under which the modern Democratic Party operates, we should immediately expand Obamacare even more! Meanwhile, the Republican leadership is scrambling to prop up Obamacare due to their terror that everyone will blame them for its problems, even though they opposed Obamacare from the beginning, never wrote one word of the law, and contributed not a single vote in favor.

You can’t make this stuff up.

Appeals court rules against Obama immigration executive order

2:42 pm

The law is such an inconvenient thing: A federal appeals court has sustained a lower court injunction halting the Obama administration’s effort to make up law and issue amnesty to illegal immigrants.

Three significant take-aways from this:

  • 1. The case will now proceed quickly to the Supreme Court.
  • 2. The courts appear to be united against Obama’s illegal action, a fact that to me is a relief considering the number of Democratically-appointed judges in recent years who have allowed their partisan leanings to influence their decisions.
  • 3. This will strengthen the hand of the lower court judge whose injunction was defied by the Obama administration, making it easier for him to impose serious contempt charges against Obama officials and Department of Justice lawyers.

Overall, this and other recent court rulings against the Obama administration give me hope that we are still a nation of laws, not men, and that we will weather this bad period and come out of it intact as a free nation.

Senate Republican leaders ready to cave to save Obamacare

11:36 am

In the mistaken belief that a court ruling against Obamacare subsidies would damage Republicans, Senate Republican leaders have written a bill that would nullify the court ruling and save Obamacare.

With several Senate Republicans facing tough reelections, and control of the chamber up for grabs, 31 senators have signed on to a bill written by Sen. Ron Johnson (R-Wis.) that would restore the subsidies for current Obamacare enrollees through September 2017. But the administration would have to pay a heavy price — the bill would also repeal Obamacare’s individual and employer mandates and insurance coverage requirements. …

But even if Johnson could somehow persuade Obama and Senate Democrats to accept his plan — a herculean task — the bigger problem will be his Republican colleagues in the House. The growing divide between the two chambers leaves the GOP in an awkward spot. The court could gut Obamacare in June, handing Republicans a long-sought victory they couldn’t achieve legislatively. But without a backup plan that the whole party supports, the GOP has no way to blunt the political damage if millions of Americans lose the ability to pay for their health insurance.

The madness here is in somehow assigning any blame to the Republicans. They didn’t write this law. They aren’t at fault if it goes down. The only political damage that will occur if the Supreme Court rules against subsidies will be against the Democrats. To think the Republicans will be hurt by this is plain stupidity, which isn’t surprising coming from a Senate leadership run by Mitch McConnell with the help of John McCain.

The Republicans should be arguing that, following a court ruling against Obamacare, the best solution would be to repeal the law outright and start over. Period. That is what the public wants, and has wanted, in poll after poll now for seven years, beginning two years before the law was even passed and continuing even as the law has increasingly gone into effect.

If the Democrats refuse to agree to a repeal than they will be the ones once again causing the problem. The Republicans shouldn’t be afraid to make this clear.

New world record for longest hoverboard flight

9:04 am

The inventor of a hoverboard designed to be flown by an individual standing on the board has set a new world record, flying more than 900 feet.

Canadian inventor Catalin Alexandru Duru traveled a distance of 275.9 m (905.2 ft) on a propeller-based hoverboard he created himself. The machine was reportedly designed and built over the course of 12 months. “I wanted to showcase that a stable flight can be achieved on a hoverboard and a human could stand and control with their feet,” Duru is quoted as saying to Guinness World Records, which has recognized the feat.

Video of the flight is below the fold. It appears he essentially scaled up a drone to carry human weight.

The Russian investigation into Progress failure stalled?

8:47 am

Internal disagreements appear to be hampering the investigation into the Progress launch failure in late April.

The investigation had been leaning to pinning the failure on the disintegration of the Soyuz third stage oxygen tank. Others, however, are now claiming that the disintegration itself was caused by an improper separation of Progress from the rocket. The result is that the investigation has delayed the release of its findings.

UAE establishes space agency
