Voyager 1, which left Earth in 1977 and is now about 10 billion miles away has entered a region of space with strange anomalies, according to project scientist Ed Stone, former director of the Jet Propulsion Laboratory The spacecraft has encountered magnetic potholes and bumps—areas where the magnetic field of the heliosheath either nearly vanishes or doubles, respectively It also has encountered ‘anomalous cosmic rays’ that are less energetic, and thus less dangerous, than galactic cosmic rays.
