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 ...

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 ...

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 ...

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 ...

Almost every day, the great antennas of NASA’s Deep Space Network turn to a blank patch of sky in the constellation Ophiuchus. Pointing at nothing, or so it seems, they invariably pick up a signal, ...

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 ...

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 ...

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 ...

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, ...
