New Horizons' Latest: Fly Over Pluto's Ice Mountains and Alien Plains The hit parade from NASA's New Horizons mission to Pluto continued on Friday with views of an alien-looking plain in the dwarf planet's "heart," dark streaks on the surface that look like windswept trails, and mountainous terrain named after Everest climber Tenzing Norgay. The focus of Friday's news conference, conducted at NASA Headquarters in Washington, was the frozen plain in Pluto's light-toned, heart-shaped region. The "heart" is informally called Tombaugh Regio — named after the late astronomer Clyde Tombaugh, who discovered Pluto in 1930. New Horizons' scientists call the plain "Sputnik Planum," or Sputnik Plain, after the Soviet satellite whose launch opened the Space Age in 1957. The plain is dominated by polygon-shaped hills that are roughly 12 miles (20 kilometers) across and divided by what appear to be shallow troughs. Some of the troughs are filled with darker material. Others are traced by bumpy hills. And some of the polygons have pitted surfaces. In New Horizons' view, which spans about 300 miles (500 kilometers), there's nary a crater to be seen. "This terrain is not easy to explain," said Jeff Moore, a planetary scientist from NASA's Ames Research Center who leads New Horizons' geology, geophysics and imaging team. This is a view of Sputnik Planum, an area in the center left of Pluto's heart-shaped region (known as Tombaugh Regio). It's a vast, craterless plain that may be no more than 100 million years old and still under the influence of geological processes. The surface appears to be divided into irregularly shaped polygonal segments that are ringed by narrow troughs. Some of the troughs are filled with dark material (lower left). Other troughs show evidence of mounded-up material (center right), and some of the polygonal segments are mottled by pits (lower right). NASA / JHUAPL / SwRI The pits may have been formed by sublimation, in which ice turns directly from a solid into a gas. In Pluto's case, the surface is covered with a layer of frozen nitrogen, methane and carbon monoxide. A preliminary analysis of spectral data revealed that there's a high concentration of carbon monoxide ice on the left side of Tombaugh Regio. As for the polygons themselves, "the surface that is most reminiscent of the surface you're looking at is the high latitudes of the northern hemisphere of Mars," Moore said. The polygons in Mars' north polar region were formed by thermal contraction. That's similar to what happens when a patch of muddy ground dries on Earth. On Pluto, the polygons may be the result of a similar process, or they may have been formed by convection — like blobs of wax in a lava lamp, or blobs of oatmeal in a cooking pot. "It's just really too early to say," he said. The bottom line is that even these early pictures show that Pluto is much more than a frozen iceball. "Pluto is every bit as geologically active as any other place we've seen in the solar system," Moore said. The green area in this picture of Pluto indicates higher concentrations of carbon monoxide ice, as observed by New Horizons' Ralph instrument on July 14. The contours indicate that the concentration of frozen carbon monoxide increases toward the center of the "bull's eye." Scientists don't yet know the reason for the concentration, but one possible scenario involves the upwelling of material from below the surface. NASA / JHUAPL / SwRI Dark streaks on the ice Some of the images from New Horizons show miles-long streaks of dark material on Pluto's icy plains. Moore said the streaks look similar to the dark wind streaks documented by Mars orbiters. Moore didn't rule out the possibility that they might be plumes of material ejected from the surface, similar to the geyser plumes spotted by NASA's Voyager probe on Triton, Neptune's largest moon. However, Moore cautioned that the team couldn't confirm the discovery of Plutonian plumes — which was the subject of speculation before the flyby. He said the "least crazy idea" was that the dark stains were produced when methane frost settles onto the surface, undergoes irradiation and turns into a darker type of hydrocarbon. Winds in the thin Plutonian atmosphere might blow the material around. The inset images highlight dark streaks of material that were spotted on Pluto by the New Horizons spacecraft. One hypothesis is that the material consists of hydrocarbons that were blown across the surface by winds in Pluto's thin atmosphere. NASA / JHUAPL / SwRI Flying over mountains and plains A couple of days ago, New Horizons' scientists were wowed by the sight of 11,000-foot-high mountains of ice on Pluto's surface. During Friday's briefing, the team unveiled a flyover video focusing on a mountainous region nicknamed Norgay Montes as well as on Sputnik Planum. Friday's flyover was simulated using stereo imagery of the region that was captured by New Horizons' Long Range Reconnaissance Imager from a distance of 48,000 miles (77,000 kilometers). The video shows features with a resolution as small as a half-mile (1 kilometer). The name given to Norgay Montes pays tribute to Tenzing Norgay, the Nepalese Sherpa mountaineer who made the first ascent to the summit of Mount Everest with British climber Edmund Hillary in 1953. Moore said that Norgay Montes would be the first feature on another planetary body named after a citizen of Nepal. Like the other names given to Plutonian features, Norgay Montes is a provisional name that technically still requires the International Astronomical Union's approval. http://www.nbcnews.com/video/fly-over-shows-soaring-mountains-on-pluto-486384195606 Pluto's 'tail' in space Preliminary data from New Horizons suggests that the solar wind is stripping away Pluto's predominantly nitrogen atmosphere to create an "ion tail" that trails behind the dwarf planet, said University of Colorado planetary scientist Fran Bagenal, one of the mission's co-investigators. "This is just a first tantalizing look at Pluto's plasma environment," Bagenal said in a NASA news release. Researchers currently estimate the atmospheric loss at 500 tons per hour, but Bagenal said much more detailed observations are due to be sent back in August NASA's New Horizons probe captured this pixelated image of Nix, a small moon of Pluto, on July 13 from a distance of about 360,000 miles (590,000 kilometers). Mission scientists believe we are looking at one end of an elongated body about 25 miles (40 kilometers) in diameter. NASA / JHUAPL / SwRI Smiley face on Nix? The New Horizons team also released a picture of one of Pluto's smaller moons, Nix, taken from a distance of about 360,000 miles (590,000 kilometers). The 12-pixel-wide picture doesn't provide much detail, but it does suggest that there's surface variation — in fact, if you squint your eyes, you can almost make out a smiley face. Previous observations have suggested that Nix is elongated, but in Friday's image, the 25-mile-wide (40-kilometer-wide) moon presents a more circular profile. It's not like the crumpled, potato-like shape of another Plutonian moon, Hydra, as seen in a New Horizons image released earlier this week. Stay tuned for more The images were the latest product of a mission that blasted off nine and a half years ago and reached its climax this week. The piano-sized New Horizons probe zoomed past Pluto and its moons on Tuesday at a speed of more than 30,000 mph (50,000 kilometers per hour), coming within 7,750 miles (12,500 kilometers) of the dwarf planet. The spacecraft is now almost 2.5 million miles (3.9 million kilometers) beyond Pluto and 3 billion miles (5 billion kilometers) from Earth. That's so far away that it takes four and a half hours for signals to reach Earth. And because of the vast distance and the trade-offs involved in designing the $728 million mission, those signals can be sent only at a rate of 1,000 to 2,000 bits per second. As a result, it will take 16 months to transmit all the data from the flyby. The next round of imagery is due to be unveiled in a week, NASA said. After New Horizons is done with Pluto, the team intends to point the probe toward one of two smaller objects a billion miles farther out in the Kuiper Belt, the broad ring of icy material beyond the orbit of Neptune. If NASA gives the go-ahead for that extended mission, such a flyby would take place around 2019. http://www.nbcnews.com/science/space/new-horizons-latest-fly-over-plutos-mountains-plains-n393911

има голяма вероятност за нов мини ледников период: Thanks To Reduced Solar Activity, We Could Be Heading For A Mini Ice Age In 2030 Life on Earth has always been dependent on the conditions of the Sun, so scientists spend a lot of time studying its activity. A recent announcement from solar scientists suggests that the Sun may soon enter a period of significant reduced activity, possibly causing a mini ice age by 2030 – just 15 years from now. These predictions were announced at the National Astronomy Meeting in Llandudno, Wales, so it hasn't been possible to evaluate the research yet. However, ProfessorValentina Zharkova from the University of Northumbria who made this announcement claims that the findings come from a computer model of sunspots that has made "unprecedentedly accurate predictions," as reported in The Guardian. The model has shown to have a 97% accuracy when mapping the past movements of sunspots, using data of solar cycles from 1976 to 2008. And if this reliability continues, then the model also has some alarming predictions for the future: a mini ice age sometime around the 2030s. To achieve these findings, the scientists mapped the movement of solar fluid that moves in roughly 11-year cycles, which correspond to weather cycles on Earth. Around the year 2022 (labeled cycle 25), a pair of waves will be moving to the Northern and Southern Hemispheres of the Sun, getting slowly out of synch and reducing solar activity – and thus our warm weather. "In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun. Their interaction will be disruptive, or they will nearly cancel each other. We predict that this will lead to the properties of a 'Maunder minimum'," said Zharkova. The Maunder minimum was a 70-year period between 1645 and 1715. The Sun produced barely any sunspots and the Earth experienced a mini ice age. Parts of northern Europe and the United States experienced uncharacteristically cold winters. The river Thames, flowing through London, even froze over for seven weeks and was passable by foot. The surface was so stable that residents could even hold 'frost fairs' on the ice. Sunspots are relatively 'cool' regions on the Sun that appear darker when photographed. They are cooler than the rest of the Sun, but they are still around 4500 K (4200ºC, 7600ºF). They are caused by a concentration of intense, magnetic field from the Sun. This inhibits and redirects the flow of hot matter to that region and makes it darker – what we call a sunspot. Sunspots last between 1 to 100 days, during which they rotate around the Sun, following the flow of solar fluid. Sunspots go through cycles of intensity and sparsity based on the motion of the fluid cycles. There are two main waves that are slightly offset over time, producing periods of maximum and minimum solar activity. "Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity," Zharkova said. "When they are out of phase, we have solar minimums. When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago." Central Image: We generally associate a 'spot' with a small feature. However, this sunspot is 20 times the size of Earth. This one would have been visible to the naked eye - but you should never look at the Sun with unprotected eyes! NASA. http://www.iflscience.com/environment/we-could-be-heading-mini-ice-age-2030

Parents' Views on Vaccines are Changing A third of parents now perceive vaccines as more beneficial than they did a year ago, according to a new poll. The multiple outbreaks of measles and whooping cough in the past year may have affected parents, whose views on vaccines are becoming more posiResearchers from the University of Michigan’s C.S. Mott Children’s Hospital designed thepoll to measure the opinion of 1,416 parents around the U.S. on the benefits and safety of vaccines and whether there should be school entry requirements for vaccination. The poll found that 34% think vaccines are more beneficial, 25% thought vaccines were safer and 35% were more supportive of requiring vaccines for school admission than a year ago. “Over the last year there have been high-profile news stories about outbreaks of vaccine-preventable diseases like measles and whooping cough. These news reports may be influencing how parents perceive childhood vaccines across the country,” said Matthew M. Davis, director of the National Poll on Children's Health, in a statement. High profile cases, like the measles outbreak at Disneyland and the first U.S. measles death in over a decade, have affected how parents view the risk of contracting illnesses like measles or whooping cough. Two out of every five parents believe a child's risk of contracting measles in the U.S. is higher than what it was a year ago. Only 5% thought vaccines were less beneficial and less safe, while 6% were less supportive of requiring vaccines for school admission than they were last year. The vast majority of parents polled – 68% – didn't change their opinions on vaccines. Davis told NPR: "These numbers are incredibly high, and suggest that parents are hearing about the outbreaks and responding." While parents appear to be more favorable to vaccination, Davis points out that “the impact of such shifts in perception will ultimately be measured by whether more parents vaccinate their kids.” http://www.iflscience.com/health-and-medicine/parents-views-vaccines-are-changing

Всяка държава за всяка война си има лесно смилаема митология от измислени или частично измислени героизирани персонажи като повод за иницииране на първосигнална нацинална гордост. Въпрос на пропаганда. Нашият принос е напълно спекулативното твърдение, че сме въвели първи бомбардировките със самолет. Иначе съветски герои през ВСВ - бол. Но това, както отбеляза Сгоедин е друга тема.

Капитулацията на Япония следва непосредствено след разгрома на Квантунската армия в Манчжурия от съветските сили /СССР се намесва по молба на САЩ, за да бъде ускорен краят на войната/. Колкото до откриването на евентуален втори фронт срещу СССР от жълтурите през 42-ра, то мисля че битката при Халкин Гол през 1939 г. е красноречива колко могат последните. А и няма кой да драпа през Сибир без техника и снабдяване, само и само да подпомогне германците. Ето горе долу с какво разполагат съхопътните сили на японците: Така че стига фантазии. Трябва да се чете повечко.

Идеята на криптовалутите е, че се генерира ограничен брой единици. Т.е. стойността им би трябвало да нараства във времето /ако всички приемат да търгуват по този начин. Традиционните валути се обезценяват във времето, защото отдавна не са обезпечени със злато и се печатат според финансовите спекулации на борсовите пазари. Демек стойността им е колкото на намагнитена тоалетна хартия.
