As Voyager 2 crosses into the mysterious boundary of interstellar space, it has encountered something scientists are calling ...

NASA's Voyager 2 spacecraft completed a historic flyby of Uranus, becoming the first,and so far, only probe to closely study ...

Voyager 2 and its twin, Voyager 1, launched a few weeks apart in 1977 to perform an unprecedented "grand tour" of the solar system's giant planets — Jupiter, Saturn, Uranus and Neptune.

Voyager 2 is only the second spacecraft to travel this far out into the solar system. At a distance of about 11 billion miles from Earth, Voyager 2 is well beyond the orbit of Pluto.

The milestone makes the 41-year-old NASA probe just the second human-made object, after Voyager 1, to reach such distant regions. Now, Voyager 2 is over 11 billion miles from the sun — and counting.

Voyager 2’s nuclear power source should hold out until 2025 or so—likely long enough to sample interstellar space—but precisely when that data will come in is anyone’s guess.

NASA says its Voyager 2 probe has become the second human-made object to fly into interstellar space — six years after its twin spacecraft, Voyager 1, became the first.

Originally launched in 1977, Voyager 2 has been making its way through space for over 40 years now. Of course, all that time in space means that, eventually, the probe’s power supply will give out.

Voyager 2, which is nearly 46 years into its mission, is roughly 12.4 billion miles from Earth. In 2018, the spacecraft left the heliosphere, ...

NASA announced the arrival of Voyager 2 in interstellar space on Dec. 10, 2018. Voyager 1 reached the milestone in 2012. (Image credit: NASA/JPL-Caltech) ...

Voyager 2 was only expected to last for five years, but it’s still operating 42 years after launch. Yet Saturday, January 25, the probe did experience a bit of a hiccup 11 billion miles from ...

NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.
