11 billions miles away from earth.... Launched in 1977, the NASA Voyager spacecraft recently entered a mysterious zone located between our solar system and the great frontier of space beyond. Physicists are puzzled since their theories didn’t predict anything like it.As Voyager-1 whizzes through this unchartered frontier, a place so distant that charged particles from the sun have virtually disappeared, astronomers are struggling to make sense of the steady stream of data being returned to Earth. Astronomers initially believed Voyager-1, which is about 11 billion miles from earth, had reached interstellar space on August 25, 2012, becoming the first man-made vehicle to breach the threshold of our solar system. But feedback from the spacecraft, which showed that the sun’s magnetic field was still exerting its influence on the probe, quickly cooled that theory
