On our planet, now there are processes, which may be a significant threat to all life on Earth, as well as lead to its complete disappearance. One of these processes may be the loss of Earth's magnetic field, and the current data suggest that the likelihood of such a development as the years increase. Change of poles is underway. Where will this lead? As you know, our planet's magnetic poles is caused by features of a solid and a liquid core of the Earth. Their interaction is based on the principle of the core around which is laid turns of copper wire. The impact of facilities Read more [...]
German scientists found that the Earth's magnetic field is developed with incredibly fast since modern humans first mastered Europe, reversing the poles of its less than a thousand years, news agencies reported, with reference to the German Research Centre for Geosciences.
Previously it was thought that the Earth's magnetic poles switch places every few hundred thousand years. However, German scientists have refuted this theory. According to an expert on paleomagnetism of the German Research Centre of Geosciences Norbert Novatsuk, now the magnetic poles change places only 41 thousand Read more [...]
Julian Turner, a geophysicist at the University of Victoria, has proposed to use the analysis of stones, of which the natives of New Zealand held their pockets, to study the evolution of the magnetic field of the Earth. C report the preliminary results of the study was presented at the American Geophysical Society, and its summary results BBC News Existing data on the history of Earth's magnetic field are mainly to the northern hemisphere, while to understand its evolution knowledge of the southern hemisphere is not as important.One of the main ways of studying the history of magnetism - analysis Read more [...]
Stargate, magnetic portals, vortexes in space: science fiction writers give various names unusual holes in space / time, to explain how travelers from distant regions of space, time, or both of them to come into the orbit of the Earth. But it is - just a trick of science fiction, an occasion to tell a good story, is not it?It turns out that they do exist, although the opening is said to be in its early stages. Researcher at the University of Iowa funded NASA suggested how to find them. However, some believe that it is - old news in the "advanced civilization" chosen people that visited Read more [...]
Two years ago, scientists at the Harvard-Smithsonian Center for Astrophysics (USA) announced the discovery of two giant twin lobes formed by gamma radiation, to retire on 50 thousand light-years above and below the plane of the Milky Way. It seemed that these bubbles came from the field of the supermassive black hole Sagittarius A * at the galactic core. There is even a theory that the "gamma-petals" are generated by emission from the vicinity of SMCHD Sagittarius A *. The alternative hypothesis, put forward at the same time, it is assumed that the reason for their occurrence, by contrast, Read more [...]
Despite the lack of obscheplanetnogo magnetic field, the ionosphere of Venus, interacting with the solar wind, can form magnetic rope.Venus Express spacecraft observed in the upper atmosphere of Venus, the so-called magnetic rope (flux ropes) - great education for hundreds of kilometers over the poles.Something similar was observed on other planets, including the Earth: on these routes passed superheated plasma. Why they appear on Venus, as long as the hold and dissipate, remains a mystery. Their mere discovery was a surprise.Image NASA / Magellan.Magnetic rope - the result of a joined Read more [...]
According to information obtained from the probe Voyager 1, the edge of the solar system and deep space there is a kind of customs. Where the magnetic field lines generated by the sun and the presence in the solar wind undergo reconnection with the field lines of the magnetic field of the interstellar medium.According to journalists, the device is now Voyager, zpauschenny in 1977, is close to the edge of the heliosphere, the solar region of space where solar wind plasma is moving relative to the sun at supersonic speed. As explained by astrophysicists from outside the heliosphere bounded collisionless Read more [...]
10/12/2012Employees of the Pulkovo Astronomical Observatory of RAS for the first time found evidence of the presence of a strong magnetic field in the accretion flow of the star system.Previously, something like that was revealed only in relation to black holes and neutron stars.In 1971, the Soviet physicist Victor Schwartzman first showed that the presence of a strong magnetic field in a substance, addictive black hole, could significantly change the process of absorption in general. Own magnetic field flux, under certain conditions, is able to stop the fall of the substance at a distance Read more [...]
Although the core of the "super-Earths" due to excessive pressure is not able to operate the magnetic dynamo, like Earth's magnetic field are still possible: it turns out, magnesium oxide, a hard ground conditions, in their robes must be liquid.Many astronomers believe most of the "super-Earths" lifeless, because they do not have the most important components of the magnetic dynamo, which generates a magnetic field (which protects, for example, the Earth). The reason, presumably, is too much pressure in the core, for it excludes the hydrodynamic behavior, as well as effective Read more [...]
Salmon stored magnetic map of the area, which once born, and returning to their home river, follow familiar indicators of the magnetic field of the Earth.After a few years spent at sea, salmon returning to the rivers, and the fish are just exactly the river, from which they emerged. Such amazing peg to the house is not only the fish - just old place turtles, seals, whales and dolphins. The question is, how do they manage so well find their way home?According to researchers from the University of Oregon (USA), when returning home salmon use a magnetic map. That is fish remember the magnetic Read more [...]
Technology of the 21st century civilization drew a very dangerous and delicate angle. In general, technologies that use the banking system, meal delivery, electrical, utilities, communications, almost all of the modern world may collapse if things go wrong.
Unfortunately, many are not, and the chances that it will be even worse, increase. Moving part of the growing danger of unstoppable, accelerating the shift of the magnetic poles of the Earth. The magnetic field acts as a shield to protect the fragile new electronic technology changes people from the sun and the surge in the solar wind, which Read more [...]
After a long nine-year period of unusual calm the sun with the onset of August there was a sudden and sharp increase in its activity, according to the influential British science weekly New Scientist.
August 1 on the surface of the sun leading astrophysical observatories of the world have been recorded two giant flare. Having a magnetic nature, they were accompanied by two powerful explosions that led to the release of huge amounts of energy. A number of experts say the true "cosmic tsunami." The peculiarity of the situation is that coming from the sun stream of excited particles Read more [...]
For half a century anomaly "grew" twice. Irkutsk scientists conduct research on Lake Baikal. This time the object of study was the magnetic field.
Behind is tens of kilometers. How many more - is unknown. Two years ago, scientists measured at Irkutsk Baikal ice earth's magnetic field and suddenly found an anomaly. In the summer of continued research on Olkhon Island, and it turned out - the data going through the roof here.
- We conducted an expedition in the winter, making a magnetic survey on the ice. And determined that in the academic area of the underwater ridge magnetic Read more [...]
The core of our planet is inextricably linked with the magnetic field of the Earth. In XVII century, it was observed that the dipole magnetic field of the planet is substantially changed. The geomagnetic field has a fixed component - the dipole field (its contribution 99%) and variable (1%). Main magnetic field configuration is almost the same round of the current (dipole), which is offset from the center of the earth, and the axis is inclined to the axis of rotation of 11.5 degrees. The average field strength - 0.56 Oe. The magnetic field extends to 20-25 Earth radii and forms a kind of protective Read more [...]

Detection by satellite radiation belts around the Earth has radically changed our understanding of the value of the magnetic field in the evolution of organic life.
Sun, in the depths of which reigns temperature is about 13 million ° C, and on the surface - about 6000 ° C, every second emits 3.8 × 1026 joules of energy. At the Earth receives only one two-billionth of the energy of the sun, but it is enough for the emergence and development of life. Sun sends to the Earth are two types of radiation, electromagnetic wave lengths of a millionth of a millimeter to tens of kilometers and streams Read more [...]
There is the assumption that the source of heat is the world's natural nuclear reactor in uranium several kilometers in diameter in the center of the world [Anisichkin 1998]. Under certain conditions, suggests B. Anisichkin, for example, in a collision with a large comet, he can go into a supercritical state and cause the explosion of the planet, which, perhaps, was the reason for the explosion of Phaeton, from which may have formed part of the asteroid belt. Theory is obviously debatable, since the very existence of the Phaeton is not proved, and on the contrary, it is believed that the Read more [...]
We live in period weakening and likely subsequent reversal of the magnetic field of the Earth. By itself, the inversion of the magnetic field does not lead to the extinction of people, because reversal has occurred many times in the past without any noticeable damage. In the middle of a reversal in the magnetic field may soon drop to zero or pole can be oriented to the sun, when will the equator, leading to intense charged particles sucked into the Earth's atmosphere1. However, the simultaneous combination of three factors - the drop to zero of the magnetic field of the earth, ozone depletion Read more [...]
We live in period weakening of the magnetic field of the Earth and is likely to follow its polarity. By itself, the inversion of the magnetic field does not lead to the extinction of people, because reversal has occurred many times in the past without any noticeable damage. However, the simultaneous combination of three factors - the drop to zero of the magnetic field of the earth, the depletion of the ozone layer and the strong solar flare will lead to the collapse of all electrical systems, which may result in the fall of technological civilization. And he is not even afraid of the collapse, Read more [...]
