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

The discovery challenges findings made by Voyager 2, which collected data suggesting Uranus, unlike other giant planets in ...

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.

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.

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.

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.

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.

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 was launched in August 1977, 16 days before Voyager 1, which explored Jupiter, Saturn and Saturn's large moon Titan before heading out into the depths of the solar system.

Voyager 2 visited four planets: Jupiter in July 1979, Saturn in August 1981, Uranus in January 1986 and Neptune in August 1989. "Both Voyager 1 and Voyager 2 provided tremendous legacies for ...

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 ...
