NASA Spacecraft Discovers Strange Magnetic 'Ribbon' At Edge Of Solar System

Scientists from NASA have uncovered a strange magnetic field surrounding our solar system, shedding new light on the mysterious boundary between our solar system and interstellar space just beyond the heliosphere. Combining observations of cosmic ray particles streaming in from other parts of the Milky Way with measurements from NASA's Interstellar Boundary Explorer, or IBEX, scientists are getting a better idea of the forces at work at our cosmic borders.
