Are we there yet? The longest car ride ever…
It’s a big day for science! After 42 years, NASA announces that the Voyager 2 spacecraft reached interstellar space.
It was an 11.1 billion mile journey the outer boundary of our solar system. Voyager 1 (also launched in 1997) accomplished this milestone in 2012. We knew when Voyager 1 left the bubble of the solar system when it transmitted a different sound back to us as it passed into interstellar space.
If you thought THAT was a long ride, consider that (even traveling at 55,230 km/hour) it will take another 40,000 years for the Voyagers to reach the next closest star, Alpha Centauri. It’s a big universe out there!
