| | Voyager 1 Approaches Solar System's Outer Limits |
 | | Voyager 1 is the farthest manmade object in space, and from about Aug. 1, 2002 to Feb. 5, 2003, scientists noticed unusual readings from several instruments on the spacecraft indicating it had entered part of the solar system unlike any encountered before. |
 | | Voyager 2, which launched on Aug. 20, 1977, and explored Jupiter, Saturn, Uranus and Neptune, is also moving out but in a southward direction and hasn’t traveled as far. |
 | | Analyzing six months of data from Voyager’s Low-Energy Charged Particle instrument, a team led by Dr. Stamatios Krimigis of The Johns Hopkins University Applied Physics Laboratory (APL), Laurel, Md., determined that the spacecraft, while nearly 8 billion miles from Earth, passed through and later returned behind the turbulent zone known as the solar termination shock. |
