WASHINGTON (AFP) NASA's Voyager 1 spacecraft has reached the outer edge of the solar system where wind from the Sun is no longer blowing outward, but sideways, the US space agency said.
The spacecraft was launched in 1977 and has since snapped images of Earth and other planets in the solar system and provided NASA with crucial information as it makes its long journey into outer space.
NASA researchers think Voyager 1 will leave the solar system and enter interstellar space, or the area in between the end of the Sun's influence and the next star system, in about four years.
For now, Voyager 1 is 17.4 billion kilometers (10.8 billion miles) from the Sun in "an area where the velocity of the hot ionized gas, or plasma, emanating directly outward from the sun has slowed to zero," the space agency said.
"Scientists suspect the solar wind has been turned sideways by the pressure from the interstellar wind in the region between stars."
NASA noticed that the solar wind's outward speed had slowed to zero back in June, but wanted to look at readings from Voyager 1 over the next four months to be sure.

From @voyager2
Sister ship Voyager1 is 16 hrs 07 mins 28 secs of light-travel time from Earth
Those four craft (the two late-number Pioneers and the two Voyagers) are moving faster than any human artifacts, ever. And after more than thirty years, they haven’t traveled more than a tiny fraction of a light year. :’)
