For the past decade or so, scientists have been waiting for the Voyager 1 spacecraft to cross into deep space. New research suggests it already has — over a year ago.

When Voyager 1 and 2 crossed the boundary of the heliosphere, many believed they would drift silently into a cold, empty ,voidinterstellar space. It was expected to be a lifeless region, too sparse ...

It's been almost 40 years since Voyager 2 flew past Uranus, but its readings from that whistlestop flyby have remained some ...

The Voyager 1 spacecraft will soon have a new territory to explore--interstellar space. Voyager chief scientist Ed Stone discusses whether the spacecraft will have a bumpy exit from the solar ...

After Saturn, Voyager 1 zoomed away from the plane of the solar system, leaving the planets behind. Voyager 2, which was on a slower trajectory, flew past Uranus in 1986 and surprised astronomers ...

Voyager 2?s journey toward interstellar space has revealed surprising insights into the energy and magnetic forces at the solar system?s outer edge, and confirmed the solar system?s squashed shape.

Has Voyager 1 left the Solar System at last? The data have been ambiguous to say the least, with the number of announcements on the topic rivaling Spinal Tap drummers.

NASA's Voyager 1 spacecraft launched 35 years ago today (Sept. 5). But the space probe has farther to go than thought to pass beyond the solar system's edge, scientists say.

Why Voyager 2 Is In Interstellar Space But Not Out of the Solar System There's a good difference between where the sun's energy ends and where its gravity ends.

Voyager explored solar system using 8-tracks and aluminum foil <b>Television •</b> PBS’ “Farthest — Voyager in Space“ recounts amazing journeys of probes built with 1970s technology.

And, rather than falling off a cliff when the probe reached interstellar space, solar particles continued to strike Voyager 2's sensors for more than 50 days after the transition.
