voyager 1

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.

On this day 35 years ago, NASA's Voyager 1 spacecraft took a picture that changed how we see our planet. The iconic "Pale Blue Dot" image is just as awe-inspiring today.

NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter, engineers are assessing the problem from 15 billion miles away.

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power.

The Voyager I spacecraft went haywire last year, but NASA engineers say they have finally fixed its data transmission systems and are receiving usable signals from all four science instruments.

Some experts believe that the solar system's hypothetical ninth planet could be just a few years away from being discovered. If this is the case, how long would it take for humans to send probes to the elusive world?

Two of the four science instruments aboard the Voyager 1 spacecraft are now returning usable data after months of transmitting only gibberish, NASA scientists have announced.

NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.

Voyager 1 has been sending a stream of garbled nonsense since November. Now NASA engineers have identified the fault and found a potential workaround.

After four months of being unable to detect comprehensible data from the Voyager 1 spacecraft, NASA scientists have had fresh luck after sending a "poke."
