When the stars collide occurs ... gold!

When the stars collide occurs ... gold!
It is one of the great astronomy fun facts: most of the elements that make up our bodies did not exist when the universe was young. Then there was nothing except hydrogen, helium and lithium. Heavier elements such as iron are forged heat and pressure deep within the star much later.

Even stars can not create heavy elements like gold. This requires an incredibly strong shock wave, and until now it was not known what might fire him.

However, the team of astronomers from the Harvard might be able to come up with an answer.

The gold was created using titanium collisions between neutron stars - incredibly massive layers of the star remains after her death.

"People have raised a lot of random data, but until now it comes to actually debate was no concrete evidence and facts," said study leader Edo Berger.

However, everything changed last month when NASA's orbiting telescope detected beams of high energy gamma rays, which lasted only two tenths of a second.

These beams of gamma rays appear to be constant in the universe, but as bundles of long duration cause a supernova, or exploding star, bundles of short duration has not yet been able to explain.

When these beams flashed, astronomers immediately directed another telescope in Chile in the same spot and caught the glow of visible light. Once a week the Hubble telescope focused on the same spot, the light was still present, although much faded.

The characteristics of this light can be explained by the explosion of new atom whose mass is nearly 3,000 times the mass of the earth of which are radioactive and cause seeding. Some atoms of platinum, lead, and other heavy elements while some weighing several times the mass of the moon, pure gold.

The best explanation for this intense beam would be a clash of two neutron stars. Collisions are astounding and happen very quickly, and theorists believe that the neutrons are crucial for the formation of heavy elements.

Do these collisions in our system comes once in 100,000 years on average, and this could explain the lack of funds in our galaxy.

If you were able to hear frequencies lower than 20Hz, you could hear your muscles moving!

Our senses are amazing things. Although they don't give us a completely accurate picture of the world, they give us just enough information to be able to carry out our lives.

For example, you might know that humans can't ever hear certain sound frequencies. However, that's not such a bad thing. If you could hear frequencies under 20 hertz, you would actually be able to hear your muscles move!

Discovered a new moon of Neptune

Discovered a new moon of Neptune
The space telescope "Hubble" discovered a new moon orbiting the planet Neptune, confirmed by the U.S. agency NASA.

The moon is named "S/2004 S 1" and now it is 14 known moon orbiting a massive planet. This is the smallest moon in the Neptune system. Diameter is only 20 kilometers, and a full circle around Neptune made ​​every 23 hours.

American astronomer Mark Šovolter noted the point, as he studied segments of Neptune's rings.

NASA says the moon is about 100 million times paler than the weakest the stars visible to the naked eye. The moon is so small that it spaceship "Voyager" was not detected when it passed close Barely in 1989. year and explored the planetary system.

Šovolter observed movement of bright spots over 150 images of Neptune that the "Hubble" made ​​since 2004. by 2009. year.

When the atoms become quantum

Millennia atoms are represented phantoms whose existence is only hinted at but they stubbornly remained invisible. It was believed that the remains indivisible, and are so called, according to the Greek 'indivisible'. In the early 20th century, physicists knew that atoms carry a charged parts. Model which is usually resorted consisted of positively charged ball 'pudding' with the negatively charged "plums", Electron. Picture is broken Ernest Rutherford in 1911. when he asserted that the positive 'pudding' all compacted into dense core, or nucleus, and that the 'plum' electrons around the bay.
Rutherford's atom is even more puzzled scientists, since it went against all the laws of physics. The opposite charges are inexorably attracted to electrons and by law should end up in a spiral of positively charged nucleus in less than a millisecond, (and if not, their mutual negative charge would throw them out of orbit). But atoms are somehow successful housing the negative and positive charges.
This paradox is resolved Niels Bohr exactly a hundred years ago when he successfully merged with the new standard physics quantum theory from which further developed the model of atomic structure.
And more. Together the theory with experiment, understand the basics of how atoms and molecules are connected into. He explained that until then mysteriously repeat the properties of chemical elements that are visible on the periodic table. Most importantly, it revealed the fundamental role of quantum physics in the reality that surrounds us.
Although the technical details of Bohr's model turned out wrong, his approach is a significant observation of the atom, and it is to liberate the conclusions of which leads us to common sense and ignore the strange rules of quantum theory. Boron is unlike his contemporaries realized that the acceptance of quantum physics, the key to hidden secrets of nature. While other quantum confusion to despair, Pine headed path that led him to 'forest', and when the path forked into two paths going to both but remaining a traveler. He insisted that knowledge of reality means accepting the truth and mutually incompatible.
In the decades after his description of the atom, Bohr was a guide and interpreter among physicists who threw themselves to research the strange new world of the quantum. As noted J.R.Openhajmer in the development of modern quantum physics, "Niels Bohr's deeply creative, keen and critical spirit has led, limited, deepened and finally turned things around."

The father of the atom
Pine role in uncovering the secrets of the atom began in 1913. when a series of three technical article outlines a new atomic science.
Bor "is the first paved a solid and lasting path to understanding atomic structure and its dynamics," wrote physicist Abraham Pais in pine biography, Niels Bohr's Times (1991), and "in this sense can be considered the father of the atom."
Like all fathers, Pine is proud child of his but he was blind not to see its flaws. From the start he realized that his model is too simple to encompass the complexity of reality. But he was convinced that the atom can only be explained by quantum physics. "And that of course is the key to success Bohr," says science historian J. Heilbron (John Heilbron), University of California, Berkeley.
That it must resort to quantum theory, Bohr realized he was preparing his doctoral dissertation in 1911. He found that the electrons that carry current behave differently from those that are related to atoms, and quite unusual compared to the mechanical laws of classical physics.
"I realized that there was no way that would be using classical physics explain the behavior of electrons in metals," says physicist Alfred Goldhaber with Stony Brook Univesity, New York.
Various solutions have hinted that the problem could be explained by applying the Max Planck's quantum idea introduced in 1900. Based on experiments with thermal radiation, Planck concluded that the energy from the hot object emits only in indivisible packets, quanta, like individual grains of sand. A few years later, Einstein claimed that all radiation, including light, not only broadcast but also conveys the 'packets' (later called photons), although it was known that the light travels as a wave.
In the first decade of the 20th century, only a few serious scientists accept Planck's idea, and fewer still believed Einstein. But Pine is. While others condemned quantum contradictions, he did investigated. Due to the circumstances in which he grew up and was brought up, ready to go out to meet the challenges.
He was born in Copenhagen in 1885. academically educated in the family, a rich intellectual environment. From an early age prusustvovao the evening discussions between his father, physiologists, and family friends, some of whom were physicists, philosophers and philologists. Boron is absorbed multicultural ideas inherited in Danish history and geography at the crossroads between Germany and England. As children, he and his brother Harald, his father read aloud Goethe, Shakespeare, Dickens. Nils has consumed the Danish authors such as Kieregaard, Hans Christian Andersen, read the unfinished novel by Poul Martin Moller (Kierkegaard mentor) Adventures of a Danish Student. Wrinkles are deep discussion seemed full of dilemmas and contradictions, and they learned the language and logic that he would return to life.
From early education to college years at the University of Copenhagen with his brilliance attracted the attention of teachers and peers. "Family and friends, as well as teachers, recognized as a rare spirit that wore down, saw him as a thinker who goes in depth and width, and they went out to meet him in all ways to develop their skills," said Heilbron.
In science education, Bohr was equally accepted the German preference for theory and mathematics and the UK, which is more concerned with experiments. Although prone to theoretical work, for post-doctoral studies chose Cavendish Laboratory in Kembriđžu, soft British experimental physics at the time.
He enjoyed the magic Kembriđža, in the laboratory and in the village. He played football, and promoted knowledge of English reading The Pickwick Papers, with a little red dictionary that bought, but he liked hearing the J.J.Tomsonom. Thompson headed the laboratory, a distinguished scientist who discovered the electron, but Pine is located omissions in his work on metal electrons. Thomson is almost indifferent crossing pine remarks. Late in 1911. Pine luck Rutherford, who had passed news conference in Brussels on the subject of quantum. Shortly after that conversation Bor goes to the University of Manchester and joined the Rutherford team.
And in Manchester Boron is initially off of electrons, including beta particles detected by Rutherford. But she realizes that her secret hiding radioactivity in the core. Thus, his quest for truth turns to the atom.
Early in 1912. Pine works feverishly and with success. "I already went to work, examining every aspect of the atom, the mister to find everything possible," said Goldhaber. In June Bor brother writes: "It seems to me that I found a little bit about the structure of atoms." Modestly speaking, because it turned out that he had discovered that quantum physics 'hold' atom.
Bor was the first to try to apply quantum physics to atoms. But it is first pointed out that it can 'work'. He said that the correct theory of stable atoms must have the dimension of length that corresponded to the size of atoms, such as fork length uslovljavlja size of a bicycle wheel. The number of reasonable length for atomic fork was accessible only using the key number in the quantum theory, which is Planck's constant, combined with an electric charge and mass of the electron and the nucleus.
Understanding how quantum physics explains the behavior of atoms did not go straight. For his model of the atom Bohr applied the classical mathematical approach and then added to quantum physics in four specific ways. The two are directly related to Planck's theory of radiation, including the technical aspects of the energy of the electron. The other two were inspired by the processes hidden in the mysterious machinations of Bohr's enigmatic mind.
The first is often hailed as a crucial ingredient in the Bohr model of the atom, the electrons can occupy only certain orbits around the nucleus. In any such permitted orbit electron has angular momentum is equal to the product of Planck's constant divided by 2 pi. With such a limit Bohr could not explain why the hydrogen atom emits light only in certain very specific colors, or frequencies. The emitted light corresponded to the electron to 'jump' from one allowed orbit to another.
Of the many confusing aspects of the Bohr atom, this was the strongest. According to standard physics of the light should depend on how long you should make the electron orbiting the nucleus, what is its orbital frequency. But if the electrons emit light as they cycle, Pine noted, the atoms would radiate light all the time, and that is not happening. Hence Pine concluded that electrons occupy non-radiating orbits, and the atom is in a state of 'sleep', divides the frequency of light frequency of the orbit.
"This is out of the ground under the feet of many physicists, who assumed that this phenomenon within the atomic processes could be directly linked to developments in the micro-world," said Heilborn meeting of the American Physical Society in April.
The second congress smart remark offered an idea of ​​how to bridge the gap between quantum and classical physics. Electron far from the nucleus, Bohr said, would the frequency of light emitted close to the classical prediction. Since distant orbits close together, the orbital frequencies are nearly equal. So you jump from one to the other emits nearly the same orbital frequency of frequencies. It is otherwise stated what we know about the great facilities, quantum effects would be too small for us to notice - a key part of the final understanding of quantum reality.
The composition of atoms

To explain the mischief of classical physics to quantum theory Bohr explanations offered so that all could not fit in a professional work. Therefore, published a series of three papers under one title, "The composition of atoms and molecules," in the Philosophical Magazine. In the first part, which was published in July in 1913., With spectrum of colors emitted by hydrogen, was described by quantum rules for the electron orbits and quantum jumps of hydrogen atoms. The second part describes the arrangement of electrons in circles around a core of more complex atoms, which is the first step towards the explanation of the periodic table of elements. The third describes how atoms form molecules with shared electrons.
The reactions of the pine theory were mixed. While some found the idea brilliant, others was incomprehensible. Einstein was intrigued, but not convinced. But when an experiment confirmed congress predictions that certain colors in the spectrum of light that was thought to have actually come from hydrogen helium, Einstein is no longer doubted. When they show up for the experiment, said "This is a major step forward, Pine theory must be true."
But Bohr knew that his theory only glimmer of insight into reality, and to have shortcomings. Is successful, he believed, largely thanks to the simplicity of hydrogen. Over the next decade, attempts to also apply to more complex elements did not give results. Finally in 1925. Werner Heisenberg, a young German physicist who studied at the Bohr Institute for Theoretical Physics in Copenhagen, created a new mathematical approach that gave the right answers. Heisenberg's work marked the birth of modern quantum mechanics.
Around the same time, experiments to determine the particles sometimes behave like waves, and vice versa. Erwin Schrodinger's wave constructed version of quantum theory, which soon proved to be equivalent Hajzenbergovoj particulate version. Heisenberg in 1927. discovered the famous uncertainty principle: it is impossible to accurately measure a few svojstvava simultaneously, such as particle position and its momentum.
Once again the Pine explain the paradox. At a lecture in 1927. proposed the principle of complementarity. The light can be a particle or a wave depending on which experiment you choose. You can determine the position of an electron, or its momentum, but to design an experiment. You can not do both at the same time.
Pine komplenemtarnost provided the basis the Copenhagen interpretation of quantum mechanics. In popular discussions this approach is put to the fore the role of observers in exposing reality, the point in bickering many physicists today. But Bohr was not talked about it in this way, says the philosopher of science Don Howard of the University of Notre Dame. Heisenberg was one that he focused on the role of observer.
Pine vision was much more subtle. He insisted that the properties of quantum systems do not have the exact meaning before they are measured. But the measure required a measuring instrument that communicates with a quantum system. Once the communication is established, an instrument for measuring a quantum system and a history become 'connected' in modern terminology. So how is it even possible to talk about the properties of a quantum system?
"This place gets Bor crucial idea in their thinking," Howard said at a meeting of physicists. If you define an experiment you want to perform, you can use the result to describe the property of a quantum system as it has the correct value, even if there is no exact value measurements. Of course, you could not talk about all the properties of the system at once, you have to choose what to measure.
"For Bor, two properties such as position and angular momentum are necessary for the complete value of the system and its behavior," said Howard. "But of them can only speak one at a time, not both at the same time, because we have to have exactly defined properties of the system only in the context in which this property can be quantified." And the context of measuring the position and angular momentum are physically incompatible . "It was a very good reason why we could not simultaneously be talking about well-defined values ​​for the position and well-defined values ​​of angular momentum," said Howard.
Multiple truths

Bohr's unique approach comes from the contradictions of his view of the world and the truth of his early youth. In fact, his research in quantum science have opened the way to a much broader view of the reality that surrounds us.
"The greatest satisfaction that earned him a research in the field of quantum physics in the wider field of philosophy was the discovery that more true ... come in complementary pairs," said Heilbron.
They recently published letters pine fiancee, Margaret Norlund, who wrote in the time of the survey atomovog model. They Bor lists various kinds of truths, those sermons, the great literary works, scientific truth, for we see that all are different but they are important. "This is something I am very touched, I can almost call it their religion - the truth is all of value."
Heilbron to see the parallels with the four methods that introduce the quantum atom - a lot of it is true, not all consistent.
"Although they differ in physical content, sometimes in conflict with math, but Bohr believed that all he needs," said Heilbron. "These four formulations Boru not only serve to define the borders of their speculations. He believed that each contains an element of truth, and therefore has an obligation to take everything into consideration, ie accept even if they are contradictory. The principle of inclusion at all costs, he became almost a religious rule. "
Standard Pine religion is not sympathetic. His mother was Jewish, which is not a practicing religious customs, Lutheran atheist father. As a guy, Niels attempted to accept the religion but soon found that she could not pass the test of logic and science. When this is the one occasion showed his father, this just laughed. This episode is described fiancee, "My courage is roaring at me, out of control, out of control, I finally know that now and I think I can."
Heilbron see in the beginning of Bohr's remarkable intellectual path.
"The encouraging smile man she admired most in the world made me feel that it belongs to the few who think freely, regardless of the standard beliefs that govern their class or culture, time or place," notes Heilbron.
Encouraged, not only thought, but he did it in a way others could think of. For him, the classical physics of uđžbenicima "far from the truth as microworld and conventional religious beliefs of the real importance of life," said Heilbron.
Bohr accepted the weirdness of the quantum world is not a heresy that should be avoided, but as a key solution to the problem. Calmness with which he approached the contradictions enabled him to formulate explanations of quantum paradoxes that have withstood the test of experiment, though many after his death in 1962. year.
Towards the end of life Boron is respected as the greatest nuclear physicist in the world. I still think that's another great physicist of all time, second only to Einstein. The legend of it was developed the 1920s and 1930s, as young scientists of all nations came to study at his institute in Copenhagen. Right there in the mid-1930s, formulated the first clear picture of the physics inside the atomic nucleus. Soon after, in collaboration with the American physicist Đžon A. Wheeler, Bohr came up with a theoretical explanation of the process of nuclear fission. Bohr atom was then finally fully constructed.
Wheeler once said that he wanted to study in Copenhagen because Bohr saw further into the future than others. How is that going for me Boru has puzzled others in much the same way that atoms are baffled physicists before Bora. Its penetration into the quantum reality it is mysterious as the strange mixture of quantum and classical physics in the hydrogen spectrum.
Perhaps, says Heilbron, his personal letters recently made public, offer new material for speculation about the Bohr genius and intellectual creativity in general.
And he adds: "His genius may not be repeated. Because, as Einstein once said, it's amazing what the mind is the Bohr did show up. "

The deepest note ever detected by mankind is in another galaxy!

The deepest note mankind has ever detected is a B♭. That is 57 octaves below middle C! Can you imagine a piano with that many octaves? The sound is made by inflating plasma bubbles in the center of the Perseus Cluster.
The Perseus Cluster or Abell 426, like it's name says, it’s a cluster of galaxies in the constellation Perseus. It is considered one of the most massive objects in the whole universe!

Dr. Andrew Fabian discovered a huge black hole in this galaxy and despite the fact that this galaxy is 250 million light years from the earth, it emits Cosmic B flat sounds which appears as pressure waves rolling and spreading as a result of outbursts from this black hole!

It seems like if music was to be created at Perseus Cluster, a whole kind of new music genres could be created.

Discovered underwater forests 50,000 years old

Group of divers found in the Gulf of Mexico unspoiled, old underwater forest more than 50,000 years.

According to the newspaper "The Huffington Post" forest covers about 0.8 square kilometers and is 16 kilometers from the coast states, Alaska, at a depth of 18 meters.

Ancient forest are remarkably preserved cypress swamp, now the habitat of various species of fish, crabs, sea sasa and other marine animals - an underwater paradise.

The leader of the divers Ben Raines was involved in the discovery and other professionals like Grant Hurley, experts for the analysis of tree rings from the University of Southern Mississippi, which is using the carbon isotope found a 52,000 year old forest.

Scientists from Alabama authorities requested permission to conduct more analysis to find out how the forest is managed to survive such a long period.

It is known that wetlands CEPRES can live more than 1,300 years.

"Scientific facts" that are total nonsense

Pushing head in the sand like an ostrich. How many times in your life have you heard this saying? Unless someone did not explain what it is, it is not surprising if, even today think that this big bird indeed react to fear as the saying goes.

"Business insider" has collected quite a few myths that we take for granted as scientific facts. The reason for their occurrence is an exaggeration of someone's salary, fears, and in some cases even turning down some scientific theory.

Here's "scientific" myths that we believe in:

- Children do not become hyperactive from sugar. This is confirmed by the number of tests in which the children were given drinks with or without sugar.
- Ostriches do not stick their head in the sand at all. When in danger, waving wings or play dead.
- You will hardly find out anything if you blow your nose and look at the color of the mucus on the tissue. - Appearance discharge varies from clear and fluid lines, the yellow-green with an array of various diseases. So the diagnosis on the basis that you can not determine.
- Hair and fingernails continue to grow after death. What actually happens is equally interesting - the skin is reduced.

- Lightning never strikes the same place. Oh yes, lightning strikes the same place twice or more.
- A coin thrown from the top of the Empire State Building will not kill the man walking on the sidewalk below. Penny in this case can reach the speed of 80 kilometers per hour, which is not fast enough to get you killed.

- Being blind as a bat does not mean being blind. All bats are can see, although many of them use echolocation to navigate. It works like sonar.
- Cracking knuckles will not get arthritis. This bone disease may be caused by other factors such as age, injury, obesity and genetics.
- It is not true that people are born with a finite number of brain cells - they are produce in process of neurogenesis in several brain regions in adulthood.
- Memory of a goldfish is actually totally OK. They can remember for months, not just a few seconds as most people think.
- Dogs and cats can see not just black and white, but they see blue and green.

- Most educated people in the early Middle Ages knew that the earth was round and not flat.
- There is no photographic memory, there is only people who remember well. No one can remember so much visual information as a camera.
- Microwave does not cause cancer. Only some types of radiation causing it. Solar radiation can cause melanoma.
- Your hair will be thicker by shaving. It's a visual impression, because after shaving hair is cut straight and not tapering towards the top like after plucking. Therefore sharper.
- Stomach does not need seven years to digest gum. Stomach does not digest, but gum need a few hours to a normal body ejected through the digestive tract.

There is an area in Canada with less gravity than the rest of the Earth!

In the 1960s, scientists began to chart Earth’s gravitational fields. You would expect that gravity be the same across the world. It’s not like you feel incredibly heavy in the United States while you practically float around in South America. You always feel the same gravitational pull.

However, they found that gravity actually did vary. In Canada, there are certain areas with less gravity than normal. The Hudson Bay, for example, is “missing” gravity.

There are two theories as to why this may be true. One theory cites convection as the cause. Convection pulls the Earth’s plates downward, which decreases the mass in that area and decreases the gravity. The other theory cites the Laurentide Ice Sheet as the cause. The Ice Sheet melted 10,000 years ago and left a huge indent in the Earth, which could mess with the gravity.

Physicists have created a "gun" that shoots antimatter

Scientists in the U.S. have created the accelerator, which serves as a source of jet particles of antimatter - a positron. The specificity of anti-matter gun is, its compactness conditioning can easily be placed on an ordinary table. Jet that produces "gun" looks like a plasma, emitted by neutron stars and black holes. Scientists believe that this table accelerator will enable the laboratory investigating the properties of these currents.

Brits test a new way of creating a child with three parents

Britain would allow the controversial technique of creating children using DNA of three people, a move that could help couples make their children do not inherit the rare genetic disease.

New technology will help women with "deficient" mitochondria that the children do not inheret defects that can result in diseases such as muscular dystrophy, epilepsy, heart problems, or mental retardation. One in 200 children are born each year in the UK with mitochondrial disorder.

For women with low mitochondria, scientists would take a healthy genetic material from the egg or emriona. Then he was transferred to the donor egg - an embryo that has healthy mitochondria, but the rest of the core DNA was removed. Thus, the fertilized embryo would be inserted into the womb of the mother.

Some groups opposed to artificial reproduction and believe that the destruction of eggs is immoral.

British tabloids attacked procedure which was first launched in 2008. and described as creating children three parents - mother, father and donors. For the claim that scientists say is incorrect because the amount of DNA from the egg donor insignificant.

"Scientists have developed a new procedure that could stop the transmission of these diseases," said chief medical officer in the UK, Dr Sally Davies.

A similar study done in the United States.

If British MPs agree, Britain could become the first country in the world where such a technique would use for making children. Experts say the procedure is applied to only a dozen women a year.

There is a planet that is made up of burning ice!

Gliese 436 B is my new favourite planet. Not because of it’s catchy name, but because of one of the most unusual properties found anywhere in our solar system. Gliese 436 B is a Neptune sized ice world, yet orbits its star at a very toasty 4.3 million miles. That’s almost fifteen times closer to its star than Mercury is to the sun. And yet 436 B stays completely frozen. It is literally an ice cube on fire. The surface on Gliese 436 B stays at a constant temperature because it is so close to its star, and that temperature is a whopping 439 °C. Given that water boils at 100 °C, the presence of ice should be an impossibility. Except its not really ice, at least not in the classical sense. It’s a phenomenon knows as hot ice or ice-ten. It would look much like the ice we have here on Earth, but if you were to and pick some up, you would need a new hand.

The vast amounts of water that make up the planet are kept in a solid state by gravity pulling the water molecules towards the planets core. This means that even the searing surface temperatures aren’t enough to evaporate the water away from the planet, instead the water molecules are kept densely packed together pulled towards the core. Gliese 436 B probably started out life as a gas giant, similar to Jupiter, orbiting a star much like our sun. That star has since entered its final stage and has exploded in size to become a Red Giant. Red Giants are much cooler than main sequence stars, with a surface temperature of around 4,500 °C. The sun will become a red giant in an estimated 5 billion years time, possibly destroying the Earth in the process. It seems Gliese 436 B wasn’t destroyed by this event as it was far enough away, but has had it’s entire atmosphere burned off leaving just a tiny ice cube floating around a dying star. Once every two and half days. On fire.

Voyager 1 discovery completely baffled scientists!

It seems that NASA's Voyager 1 spacecraft was not enough that it is only a human product that has gone farthest from Earth, but has now entered into a bizarre new region at the edge of the solar system that is completely puzzled physicists since their theories are not able to predict anything like that.

Launched 36 years ago, the spacecraft Voyager 1 and 2 have made an impressive tour through the solar system and on this trip scientists have made spectacular data.

Scientists originally thought that the entry of Voyager 1 in this new part of the universe, where the effects of the rest of the galaxy much more pronounced, will be gradual and unexciting. However, it appears that the transition is much more complicated than scientists predicted. Voyager 1 is now entering a strange region that scientists are able to understand.

"The models have predicted what the occasion might happen are completely inaccurate. Currently virtually no map that could show us what we can expect, "said physicist Stamatios Kirmigis with Johns Hopkins University.

The sun creates a plasma of charged particles called the solar wind and that instability in its atmosphere at a speed of 1 million km / h. Some of these ions are ejected at a speed that is 10 percent the speed of light and the particles also carry a solar magnetic fields.

Researchers know that Voyager 1 entered the edge of the solar wind 2003rd when his instruments showed that the particles move around subsonic speed as slowed from solar ejection.

Then, a year ago, everything suddenly went silent. Instruments Voyager 1 showed that the solar wind decreased nearly 1,000 times, to the point where they are no longer able to be identified. This transition occurred rapidly, within a few days.

At the same time, the amount of cosmic rays has increased significantly, which would be logical "that the Voyager was out of the solar wind," said physicist Ed Stone.
It looked as if the Voyager out of the solar influence.
What's the problem? If the solar wind completely disappeared, cosmic rays should be current in all directions. Instead, Voyager noted that generally come from one direction. Not only that, even though the solar particles disappeared, the instruments did not notice any change in the magnetic field around the aircraft. This is difficult to explain since it is considered that the magnetic field of the galaxy at an angle of 60 degrees to the solar field.
No one is currently not sure what's going on.
"It's a big surprise. In some way we have touched the intergalactic environment, but it is still found in the solar house, "said astronomer Merav Ofer from Boston University.
It seems like it's been out Voyager, but instead, he found himself in the lobby of the solar house with an open door that allowed to enter the galactic wind.
Not only do scientists not expect that such a lobby exists, but do not know how Voyager 1 left in him.
Some scientists predict that it will take months, even years, before it gets to interstellar space.
"However, this can happen for a few days. We do not have a model that could give us that information. And even then, the Voyager will not actually leave the star system, only the region within which the solar wind dominates. I am convinced that nature is much more creative than we are, "said Stone.

New fashion - computers on the body

Wearing a small computer in the glasses, bracelets or shoes has become a fashion trend for people who want to monitor their consumption of calories or enough sleep.

"We are moving towards an era of supporting computer. People will walk around with their personal computer networks and the bodies will have several devices to communicate with each other and with the Internet," said Van Baker, an analyst with "Gartner".

This mode focuses on devices for fitness, with the aim to provide users with insight into whether lead a healthy life. These devices use sensors that detect micro-movements and then send the information to smart phones or tablet computers, whose applications analyze data and send notifications to users.

"Among consumers there is a huge appetite for personal data and discovering ourselves, and that will only grow over time," said the founder and director of "Jobson" Hosein Rahman. His company produces electronic devices that monitor the consumption of calories people who wear them.

It is estimated that this year the world will be sold about 30 million of these devices. Of users goes beyond fitness, so they want to have a device that will enable them to recommend movies depending on their mood or apparatus that replace your car keys or house.

"It's amazing. Before us is an exciting future," said Professor Asim Smailagić, director of the Laboratory for wearable computers, Carnegie Mellon University, Pennsylvania. Smailagić began working on wearable computers on campus, over 25 years, and the first projects were the screens that are worn on the head and show the technical information necessary for the maintenance of aircraft.

Sophisticated and cheap sensors for motion, sound, Zhi-pi-es locating and advanced applications of smart phones will allow wearable computers become commonplace, said the professor.
