‘Everybody Should See This’: Perseids Light up Bosnian Sky

A meteor shower lit up the skies above eastern Bosnia Saturday night, giving star gazers a rare opportunity to see a display of shooting stars with the naked eye.

“I think that everybody should see this,” said Miralem Mehic, a Bosnian from an international group of star gazers who watched the light show at the Sand Pyramids, an area of naturally occurring sand columns, near the town of Foca.

The so-called Perseids meteor shower returns to the skies every August and are best viewed in the northern hemisphere in isolated areas where there is little light pollution.

They arise when the Earth passes through the debris of Comet 109P/Swift-Tuttle, which was discovered in 1862.

Meteors are parts of rock and dust that hit the Earth’s atmosphere, heat up and glow. Most vaporize as they descend, but some explode.

“This year the moon is young and will not obstruct the vision, so we will be able to see 100 ‘shooting stars’ an hour,” Muhamed Muminovic, a member of the Sarajevo Orion astrological society, told Reuters.

NASA Sends Parker Solar Probe to ‘Go Touch the Sun’

A NASA spacecraft rocketed toward the sun Sunday on an unprecedented quest to get closer to our star than anything ever sent before.

The Parker Solar Probe will fly straight through the wispy edges of the corona, or outer solar atmosphere, that was visible during last August’s total solar eclipse. It eventually will get within 3.8 million (6 million kilometers) of the sun’s surface, staying comfortably cool despite the extreme heat and radiation, and allowing scientists to vicariously explore the sun in a way never before possible.

No wonder scientists consider it the coolest, hottest mission under the sun, and what better day to launch to the sun than Sunday as NASA noted.

“Fly baby girl, fly!!” project scientist Nicola Fox of Johns Hopkins University tweeted just before liftoff. She urged it to “go touch the sun!”

Protected by a revolutionary new carbon heat shield and other high-tech wonders, the spacecraft will zip past Venus in October. That will set up the first solar encounter in November. Altogether, the Parker probe will make 24 close approaches to the sun on the seven-year, $1.5 billion undertaking.

​Parker watches namesake go

For the second straight day, thousands of spectators jammed the launch site in the middle of the night as well as surrounding towns, including 91-year-old astrophysicist Eugene Parker for whom the spacecraft is named. He proposed the existence of solar wind, a steady, supersonic stream of particles blasting off the sun, 60 years ago.

“All I can say is, ‘Wow, here we go.’ We’re in for some learning over the next several years,”  Parker said.

It was the first time NASA named a spacecraft after someone still alive, and Parker wasn’t about to let it take off without him. Saturday morning’s launch attempt was foiled by last-minute technical trouble.

“I’m just so glad to be here with him,” said NASA’s science mission chief, Thomas Zurbuchen. “Frankly, there’s no other name that belongs on this mission.”

The Delta IV Heavy rocket thundered into the pre-dawn darkness, thrilling onlookers for miles around. NASA needed the mighty 23-story rocket, plus a third stage, to get the diminutive Parker probe, the size of a small car and well under a ton, racing toward the sun.

From Earth, it is 93 million miles to the sun (150 million kilometers), and the Parker probe will be within 4 percent of that distance. That will be seven times closer than previous spacecraft.​

Speed record on agenda

Parker will start shattering records this fall.On its very first brush with the sun, it will come within 15.5 million miles (25 million kilometers), easily beating the current record set by NASA’s Helios 2 spacecraft in 1976. By the time Parker gets to its 22nd orbit of the sun, it will be even deeper into the corona and traveling at a record-breaking 430,000 mph (690,000 kilometers per hour).

Nothing from Planet Earth has ever hit that kind of speed.

Even Fox has difficulty comprehending the mission’s derring-do.

“To me, it’s still mind-blowing,” she said. “Even I still go, ‘Really? We’re doing that?’”

Zurbuchen considers the sun the most important star in our universe — it’s ours, after all — and so this is one of NASA’s big-time strategic missions. By better understanding the sun’s life-giving and sometimes violent nature, Earthlings can better protect satellites and astronauts in orbit, and power grids on the ground, he noted. In today’s tech-dependent society, everyone stands to benefit.

With this mission, scientists hope to unlock the many mysteries of the sun, a commonplace yellow dwarf star around 4.5 billion years old. Among the puzzlers: Why is the corona hundreds of times hotter than the surface of the sun and why is the sun’s atmosphere continually expanding and accelerating, as the University of Chicago’s Parker accurately predicted in 1958?

“The only way we can do that is to finally go up and touch the sun,” Fox said. “We’ve looked at it. We’ve studied it from missions that are close in, even as close as the planet Mercury. But we have to go there.”

The spacecraft’s heat shield will serve as an umbrella, shading the science instruments during the close, critical solar junctures. Sensors on the spacecraft will make certain the heat shield faces the sun at the right times. If there’s any tilting, the spacecraft will correct itself so nothing gets fried. With a communication lag time of 16 minutes each way, the spacecraft must fend for itself at the sun. The Johns Hopkins flight controllers in Laurel, Maryland, will be too far away to help.

​Technology catches up to the dream

A mission to get close up and personal with our star has been on NASA’s books since 1958. The trick was making the spacecraft small, compact and light enough to travel at incredible speeds, while surviving the sun’s punishing environment and the extreme change in temperature when the spacecraft is out near Venus.

“We’ve had to wait so long for our technology to catch up with our dreams,” Fox said. “It’s incredible to be standing here today.”

More than 1 million names are aboard the spacecraft, submitted last spring by space enthusiasts, as well as photos of Parker, the man, and a copy of his 1958 landmark paper on solar wind.

“I’ll bet you 10 bucks it works,” Parker said.

Samsung’s New Phone Shows How Hardware Innovation Has Slowed

Samsung’s new smartphone illustrates the limits of innovation at time when hardware advances have slowed.

The new phone, the Galaxy Note 9, will be faster and will last longer without a recharge. But while earth-shattering new features are in short supply, it will carry an earth-shattering price tag: $1,000.

The minor improvements reflect a smartphone industry that has largely pushed the limits on hardware. Major changes tend to come every few years rather than annually, and this isn’t the year for anything revolutionary in the Note.

The new phone will get some automatic photo editing and a stylus that can serve as a remote control. But the highlights will be a bigger battery, a faster processor and improved cellular speeds.

“You don’t see massive breakthroughs anymore from a hardware perspective,” said Carolina Milanesi, an analyst with Creative Strategies. “Everything is a little bit better, but nothing’s revolutionary.”

A 21 percent boost in battery capacity from last year’s Note 8 should translate to more than a day of normal use without a recharge. Samsung has been conservative on battery improvements ever since its Note 7 phone in 2016 developed a tendency to burst into flame, prompting an expensive recall and delivering a hit to the company’s reputation.

Since then, Samsung has subjected its phones to multiple inspections, including X-rays and stress tests at extreme temperatures. The company is also sending phones to outside labs, including UL, for independent safety tests.

“We’re three generations removed now,” Samsung’s director of U.S. product marketing, Suzanne De Silva, said of the company’s renewed confidence in the battery. “This is the right innovation at the right time.”

Although Samsung’s Note phones are large, niche products intended for power users, they offer a preview of what’s to come in the mass-market Galaxy S line. A dual-lens camera, with better zooming, came to the Note 8 months before the S9 Plus got it, for instance. The Note also got curved edges before that became standard on Samsung’s flagship phones.

The new phones will come out Aug. 24 in the U.S. Borrowing from the iPhone’s playbook, the Note 9 will have the same price regardless of carrier. The starting price is $1,000, an increase from the Note 8, but on par with Apple’s top-of-the-line iPhone X. The Note 9 will get double the storage, at 128 gigabytes, compared with typical high-end phones, including the iPhone X. Samsung will also sell a 512-gigabyte version for power users for $1,250.

Even though the improvements from last year aren’t huge, Technalysis Research analyst Bob O’Donnell said they will come across as major for those who haven’t upgraded for a few years.

Thursday’s announcement in New York comes about a month before Apple is expected to unveil new iPhones. There’s been speculation — unconfirmed by Apple — that all new iPhones will ditch the home button and fingerprint sensor and rely entirely on facial-recognition technology found in the iPhone X. The Note 9 will still have a fingerprint sensor on the back of the phone. In a jab at Apple, Samsung executives also frequently emphasize that their phones have standard headphone jacks, which newer iPhones no longer do.

The camera in the Note 9 will use artificial intelligence to detect what’s in a scene — whether that’s food, flowers or a sunset — to automatically tweak images to make them pop. It’s much like applying filters with an app, except that the phone will do this itself, much the way Google’s Pixel phones already do.

As with the Pixel, the Note won’t be saving a version without the tweaks. Purists can turn the feature off to get images that reflect what the eye sees — an option unavailable with Pixel. The camera will also offer a warning if someone blinked in a shot, or if the image is blurry.

The Note’s stylus will now have Bluetooth, allowing people to control phones and apps from up to 30 feet away. This will let people control music or snap selfies just by clicking the stylus.

Samsung also said the popular shooter game “Fortnite” is coming to Android and will be exclusive to Samsung phones until Sunday.

Kids + Screen Time = Dry Eyes

Kids are addicted to cell phones, tablets … anything with an electronic screen. The problem is, it’s bad for their eyes.

With the popularity of video games and online activities, dry eye is becoming increasingly prevalent in children and teens glued to their screens. The condition can cause permanent eye damage.

But, now there’s an app for that.

Optometrist explains

Professor James Wolffsohn is an optometrist at Aston University in Britain who has noticed something troubling.

“What we’re beginning to see is now with the use particularly of screens, digital screens, tablets, smartphones that even children are reporting dry eyes,” he said.

Tears contain oil, Wolffsohn explained, and your eyes should always have a thin layer of tears.

“The tear film on the front of your eye is there all the time not just when you cry. It’s less than the tenth of the thickness of a human hair, but without it you probably wouldn’t see at all,” he said.

That’s because, without tears, your eyes would dry up, likely get infected or scratched. With kids spending more and more time in front of a screen, many are at risk for developing dry eyes.

“When you concentrate very hard on a task such as on a computer screen, you blink less, and also instead of fully blinking you partially blink and so what’s happening is damage is being done to the front of the eye,” Wolffsohn said.

When tears aren’t being produced, they evaporate and leave behind their salty content, which can do further damage to your eyes.

The app

But now, there’s a smartphone app that can diagnose dry eyes. People tested it at a demonstration in London. The app asks some simple questions and tests how long you can comfortably stare at a screen without blinking.

Wolffsohn notes the irony of using an app on the very device that is causing the problem.

“We’re actually using the technology that potentially could cause problems, if you use a lot of it, to actually help us with the diagnosis,” he said.

Doctors say even if you don’t have the app, you can protect your eyes by simply remembering to blink when you’re in front of a screen. And you should remind your kids to do the same.

Kids + Screen Time = Dry Eyes

If you’ve ever spent a lot of time in front of a computer, you’ve probably come away bleary eyed. That’s because you don’t blink as much when you are working on a computer, which could lead to dry eyes. With the popularity of video games and online activities, dry eye is becoming increasingly common in children and teens glued to their screens. The condition can cause permanent eye damage, but fortunately, as VOA’s Carol Pearson reports, there’s an app for that.

Tesla Board Evaluating CEO Musk’s Idea to Go Private

Tesla Inc’s board said it was evaluating taking the company private, a day after Chief Executive Elon Musk surprised shareholders with the idea of launching the biggest leveraged buyout of all time.

In a statement on Tesla’s website on Wednesday, six of Tesla’s nine directors said the board had met several times over the last week to discuss such an idea and was “taking the appropriate next steps to evaluate this.”

Musk said on Twitter on Tuesday that he was considering taking the loss-making electric car-maker private at $420 a share, which would value a deal at more than $70 billion. He said funding was “secured,” without elaborating.

Tesla said on Wednesday the discussions had addressed the issue of how to fund such a deal, but gave no details. The statement did not address how the $420-per-share price was established.

Several securities attorneys told Reuters that Musk could face investor lawsuits if it was proven he did not have secure financing at the time of his tweet.

Public companies have four days to report certain material events that shareholders should know about to the U.S. Securities and Exchange Commission.

Tesla’s shares were down 2.1 percent at $371.70 on Wednesday after closing up 11 percent on Tuesday.

Some Wall Street analysts were skeptical of Musk’s ability to gather the huge financial backing to complete such a deal, given that Tesla loses money, has $10.9 billion of debt and its bonds are rated junk by credit ratings agencies.

“Who gives $30 to $50 billion to buy back the shares?” asked NordLB analyst Frank Schwope. “And if you stay as a shareholder you get less information than before and you depend more and more on Elon Musk.”

The deal would be the biggest leveraged buyout of all time, beating the $45-billion record set by Texas power utility Energy Future Holdings.

The most obvious equity partners for Musk would be a sovereign wealth fund such as Saudi Arabia’s Public Investment Fund (PIF), which sources said on Tuesday had taken a stake of just below 5 percent in Tesla, or a major technology investment fund such as SoftBank Group Corp’s Vision Fund, bankers said.

China’s Tencent Holdings Ltd, which took a 5-percent stake in Tesla last year, could also be a possible partner.

Surprise move

In a letter after his tweet on Tuesday, Musk fleshed out his idea, suggesting shareholders would get the option to sell their shares for $420 each or remain investors in a private Tesla, out of the glare of Wall Street and its need for positive quarterly results.

He said that would allow Tesla to “operate at its best, free from as much distraction and short-term thinking as possible.” Some on Wall Street shared that view.

“They’re being bombarded with questions that we don’t think are as relevant to the long-term value of the company,” said Sam Korus, an analyst for ARK Investment Management, which had 443,874 Tesla shares as of June 30. Korus said he would need more details from Musk to judge whether a buyout offer would be practical and at what price it would be attractive.

Musk has been under intense pressure this year to turn his money-losing, debt-laden company into a profitable higher-volume manufacturer, a prospect that has sent Tesla’s valuation higher than that of General Motors Co.

The company is still working its way out of what Musk called “production hell” at its home factory in Fremont, California, where a series of manufacturing challenges delayed the ramp-up of production of its new Model 3 sedan, on which the company’s profitability rests.

Going private is one way to avoid close scrutiny by the public market as Musk and the company face those challenges. Musk has feuded publicly with regulators, critics, short sellers and reporters, and some analysts suggested that less transparency would be welcomed by Musk.

The six board members who issued the statement on Wednesday included James Murdoch, chief executive of Twenty-First Century Fox Inc and Brad Buss, who was the chief financial officer of solar panel maker SolarCity until it was bought by Tesla in 2016.

Other board members mentioned in the statement included Robyn Denholm, Ira Ehrenpreis, Antonio Gracias and Linda Johnson Rice. Tesla’s other board members are Musk, his brother Kimbal Musk and venture capitalist Steve Jurvetson.
