Two of NASA’s longest-running space missions, Voyager 1 and Voyager 2, have detected a searing-hot region of space where the ...

At the farthest edge of the Sun’s influence, the Voyager probes have stumbled into something that sounds almost mythic: a ...

Surprising observations from NASA’s Voyager 1 spacecraft raise questions about the radial extent of the heliosheath — the heated outer shell of our Sun’s sphere of influence — leading scientists to ...

Heading toward the edge of the solar system, NASA's aging Voyager probes have detected signs of what may be giant magnetic bubbles at the interface between the solar system and interstellar space.

Scientists have found that the pressure at the edge of the solar system is greater than expected after analyzing data collected by NASA's Voyager spacecraft—the only objects to have traveled to ...

A venerable NASA spacecraft could pop out of our solar system into interstellar space as early as next year, a new study suggests. The Voyager 1 probe, which is now about 11 billion miles from Earth, ...

As a massive bubble encasing the solar system that stretches across tens of billions of miles and protects us from harmful interstellar radiation, there is a lot for us to learn about the heliosphere.

After 41 years of travel, Voyager 2 exited the heliosphere on 5 November 2018 at a distance of 119 au. This issue features five papers reporting plasma, particle and magnetic field measurements from ...
