Voyager reaches edge of solar system and discover magnetic bubbles



The confines of our solar system are an area of ​​magnetic bubbles filled turbulence have been observed by the Voyager probes, which have managed to reach the farthest point from Earth so far. Specifically at 14,000 million miles.

Using a new computer model to analyze the data transmitted by the probes has enabled researchers to determine that the solar magnetic field is about 160 million miles wide.

The bubbles are formed when magnetic field lines, curves are rearranged, explained the team of astronomers in the journal of Astrophysique in June. The new computer model suggests that these lines are split into disconnected bubbles of the sun's magnetic field.

"This magnetic field extends to the confines of the solar system," said Merav Opher, an astronomer at Boston University.
"Because the sun rotates on itself, its magnetic field rotates and wrinkled like a ballerina's skirt. Far away from the sun, where the two Voyager spacecraft, the folds of her skirt up," adds .

By understanding the structure of the solar magnetic field, astronomers will be able to explain how cosmic rays enter our solar system and how the sun comes into play with the rest of our galaxy, the Milky Way.

Until now, most of the data indicating the existence of these magnetic bubbles coming from an instrument aboard Voyager to measure energetic particles.

Voyager 1 and Voyager 2 were launched in 1977. Have flown by Jupiter, Saturn, Uranus, Neptune and 48 of their moons, before leaving the confines of the solar system. The data collected by nine instruments carried on board makes its mission in the most fruitful scientific exploration of the solar system.
