NASA Voyager Discover Magnetic 'Bubbles' At Solar System's Edge

NASA's twin Voyager spacecraft have made a baffling discovery along their journey to the outer limits of the solar system.

Scientists studying the Voyager data noticed what may be giant magnetic bubbles located in the heliosphere, the region of our solar system that separates us from the violent solar winds of interstellar space.

The bubbles, scientists believe, form when the sun's magnetic field becomes warped at the edge of our solar system.   link
