Voyager Spacecraft’s Terrifying New Discovery In Space
The twin Voyager space probes first embarked about a month apart from each other on their historic interplanetary expedition in 1977. In 1989, only 5 days after the 12-year anniversary of its departure, Voyager 2 became the first—and, so far, the only—spacecraft to fly past the planet Neptune, which orbits at a frigid 2.7 billion miles from the Sun.
Since then, Voyager 2 has only grown more and more distant, now leaving our solar system behind at a velocity of 34,000 miles per hour. In 2018, more than 41 years after its launch, Voyager 2 crossed the threshold between our solar system and interstellar space. Although there are no more planets for Voyager to explore, the probe continues its decades-long mission into the vast and unknown regions of the cosmos.
What did Voyager discover along its journey? Which one is likely to reach the furthest into the universe? And what is that strange humming noise?
