This NASA illustration image shows a surprise from the edge of the solar system. Using a computer model based on Voyager data, scientists have shown that the sun's magnetic field becomes bubbly in the heliosheath due to reconnection. This view of the heliosheath, shows Red and blue spirals which are the gracefully curving magnetic field lines of orthodox models. New data from Voyager add a magnetic froth (Center red) to the mix. A pair of NASA probes wandering in deep space discovered that the outer edge of the solar system contains curious magnetic bubbles and is not smooth as previously thought, astronomers said June 9, 2011. The NASA Voyager twin spacecraft, which launched in 1977, are currently exploring the furthest outlays of the heliosphere, where solar wind is slowed and warped by pressure from other forces in the galaxy, the US space agency said.
