Voyager 2 Has Entered the Space Between Solar Systems
It is the second spacecraft to make the crossing into interstellar space, providing a new look at what lies beyond our local galactic neighborhood.
Long after they have stopped communicating with Earth, the twin Voyager spacecraft will forever drift among the stars.Published OnAug. 30, 2017.
The Voyager 2 spacecraft is now in interstellar space, NASA announced on Monday, making it the second human-made machine to cross a boundary that divides our solar system from the rest of the Milky Way galaxy.
“We’ve been waiting with bated breath for the last couple of months for us to be able to see this,” Nicola Fox, director of NASA’s heliophysics division, said during a news conference at a meeting of the American Geophysical Union in Washington.
Voyager 2 follows its twin, Voyager 1, which made the crossing in 2012. This time the passage into interstellar space is yielding a different set of readings, with new clues to how the sun affects space in the far reaches of the solar system.
The two plutonium-powered spacecraft, launched in 1977 to make a tour of the giant planets, are still operational and continue to explore.
