Voyager 1 Has Flown for 49 Years Without Hitting a Thing. Here’s Why

Voyager 1 Has Flown for 49 Years Without Hitting a Thing. This Seems Impossible. Voyager 1 has travelled more than 25 billion kilometres through space, and in 49 years it has never hit a single rock, comet, or asteroid. How is that possible? In this video, we explain why space is so empty. We follow Voyager 1 from its 1977 launch, through the asteroid belt, past Jupiter and Saturn, and out of the Sun’s bubble into interstellar space. You will learn: Why the asteroid belt is almost empty How Voyager 1 crossed the heliopause in 2012 Why gas at 30,000 degrees felt like almost nothing The hum of interstellar space that Voyager 1 heard Why Voyager 1 is about to be one light-day from Earth How NASA is keeping the spacecraft alive with only two working instruments If you enjoyed this video, please like, subscribe, and turn on notifications.
