NASA spacecraft exploring solar system's edge

LOS ANGELES (AP) — A long-running NASA spacecraft that's been exploring the fringes of the solar system has entered new territory.

The space agency said Monday the Voyager 1 spacecraft is in a new region of the solar system that's different than what it's been studying the past five years.

New evidence presented at a meeting of the American Geophysical Union in San Francisco shows Voyager 1 has reached a point where the sun has little influence.

Voyager 1 still has a little ways to go before it leaves the solar system and enters interstellar space — or the space between stars.

Launched in 1977, Voyager 1 and its twin, Voyager 2, are hurtling in opposite directions toward interstellar space.
