Voyager

Humanity should consider building an interstellar probe to see our neighborhood from an outside point of view, argued several scientists at a recent conference.

It's a tiny bit colder in the outer reaches of the solar system, beyond the bubble of the sun's influence, where NASA's Voyager probes are in their fifth decade of speeding away from Earth.

It was 40 years ago today that a NASA spacecraft revealed strong evidence that an icy moon of Jupiter may be able to host life.

Scientists have predicted the future of NASA spacecraft that launched decades ago, pinpointing the close encounters they will have, even after the craft are no longer functional.

It was 40 years ago today (March 5) that Voyager 1 flew past Jupiter, revealing a surprising planetary system that includes moons of ice and fire.

Voyager 2 has passed an incredible milestone in its journey to explore the solar system by entering interstellar space, but neither its travels nor its science are ending any time soon.

It's time to say goodbye to one of the most storied explorers of our age: Voyager 2 has entered interstellar space.

Going, going — nope, it's still just going, NASA says of its Voyager 2 probe, which the agency realized was approaching the edge of the solar system back in early October.
