This artist’s concept shows NASA’s two Voyager spacecraft exploring a turbulent region of space known as the heliosheath, the outer shell of the bubble of charged particles around our sun. After more ...

This incredible story officially began in April 1977, when NASA dispatched the first of two probes—known as Voyager 1 and Voyager 2, respectively—to explore the outer gas giants. Once those objectives ...

The edge of the solar system is a turbulent place, filled with a roiling sea of huge magnetic bubbles, new research suggests. The find, made with the help of observations from NASA's venerable Voyager ...

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

As they near the outer reaches of the solar system, for the past several years the two Voyager spacecraft have been sending back observations that challenge scientists’ views of the physics at the ...

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 ...

Endeavour may be grounded, but Voyager just keeps on going. NASA experts noted that more than 30 years after the twin Voyager probes set sail for space, they are now poised on the edge of the solar ...

The twin Voyager spacecraft have beamed back a set of data that reshape our understanding of what’s happening at the farthest edges of our solar system. The farther the magnetic field extends out from ...

What is the Heliosphere? What are the conditions that exist outside of it? The first question is simply a matter of definition while the second has been the subject of scientific inquiry for the last ...

Unexpected observations by NASA’s Voyager 1 spacecraft have astronomers once again revising their theories about the radial extent of the heliosheath – the heated outer shell of the solar system.

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, ...

Magnetic fields measured by Voyager 1 (V1) show that the spacecraft crossed the boundary of an unexpected region five times between days 210 and ~238 in 2012. The magnetic field strength B increased ...
