Recent observation from images by Voyager-2 space craft shows that our solar system is asymmetrical likely due to disturbances in the interstellar magnetic field.
Researchers have long suspected the solar system was bent, but never had direct evidence until now, said Voyager mission scientist Edward Stone of the California Institute of Technology.
Scientists believe the unevenness is caused by the interstellar magnetic field that is pitched at an angle to the plane of the Milky Way. Our solar system would have been spherical if there were no disturbances in the interstellar magnetic field. The nuclear-powered Voyager spacecraft, launched in 1977, are hurtling toward an uncharted region of space where the sun's influence wanes. Voyager-1 is the most distant man made object.
