NASA’s Voyager 1 probe has entered a new region of space. What’s being called the ‘stagnation zone’ is a region in the outermost layer of the solar system, just on the edge of interstellar space. Launched in 1977 and expected to run out of fuel by 2020, the longest-running deep space probe (with its twin Voyager 2) is expected to make it out of our solar system ‘bubble’ in a few months to years.

Here’s an artist’s interpretation of Voyager’s position and the relevant NASA news release.
