Voyager first spacecraft to reach edge of Solar System

NASA has announced that the Yoyager 1 spacecraft, launched originally in 1977 to survey Jupiter, Saturn, Uranus and Neptune, has observed evidence that it is on the verge of the heliopause at the edge of the solar system. Currently the spacecraft is 17.4 billion kilometers from Earth, is travelling at approximately 17 km per second and is sending signals that require 14 hours to reach Earth.
