LOS ANGELES (AP) — Readings by NASA’s Voyager 1 spacecraft confirm it’s in unfamiliar territory, but it’s still inside our solar system.

Voyager 1 is about 11½ billion miles from the sun and is poised to become the first spacecraft to break out of the solar system into the space between stars.

But it’s not there yet. The workhorse is moving through a region of space that scientists only recently discovered. This region was first described at a science meeting last year and more details were published online Thursday in the journal Science.

Scientists don’t know how far this region extends or how long it will take Voyager 1 to cross into interstellar space.

Voyager 1 and its twin, Voyager 2, were launched in 1977. Both are speeding away from the sun.
