Humans Accidentally Created Protective Barrier Around Earth


Astronauts are not in immediate danger because of the relatively low orbit of this manned mission. Today, be that as it may, they can give essential data on how people can influence space.

But the effects of these tests spread far beyond the surface of the Earth.

Very large flares can even create currents within electricity grids and knock out energy supplies.

Solar storms are known to cause disruptions to communications down near the surface.

Some tests created distortions in Earth's magnetic fields, and one even caused its own aurora.

On such test was the Teak test of August 1, 1958.

And, the effects of the Argus tests, conducted at higher altitudes, could be seen around the world. Geomagnetic storms were observed from Sweden to Arizona post the test.

In another plot twist, it seems that this bubble, which ends just at the inner edge of the Van Allen Belts, may actually provide Earth with an additional layer of protection against particle radiation coming from space, deflecting other types of harmful radiation.

In a new study, NASA has revealed that they have spotted a Man-made barrier around Earth that disallows high-energy space radiation from entering the planet.

The barrier, which comes and goes, is the result of very low frequency (VLF) communications, used to communicate with submarines deep below the surface of the ocean, interacting with space particles. NASA's Van Allen Probes, which were launched in 2012 have tracked down a circle of "bubbles", around the Earth, which scientists have dubbed as "Manmade Space Weather".

Van Allen Belts are a massive collection of charged particles that gathers influenced by the Earth's magnetic field.

The sun sends out millions of high-energy particles, the solar wind, which races out across the solar system before encountering Earth and its magnetosphere, a protective magnetic field surrounding the planet.

These VLF ripples are pushing further back what the University of Colorado scientist Dan Baker calls the "impenetrable barrier". Indeed, comparisons of the modern extent of the radiation belts from Van Allen Probe data show the inner boundary to be much farther away than its recorded position in satellite data from the 1960s, when VLF transmissions were more limited. The misleadingly caught charged particles stayed in critical numbers for a considerable length of time, and in one case, years.

Some even failed as a result, NASA explains.

"The tests were a human-generated and extreme example of some of the space weather effects frequently caused by the sun", said Phil Erickson, assistant director at MIT's Haystack Observatory, Westford, Massachusetts, and co-author on the paper.
