NASA’s Voyager 2 spent the better part of the last 40 years making its way through the heliosphere to become the second human-made object in history to enter interstellar space, the government agency announced Monday.


The probe crossed the outer edge of the heliosphere, also known as the heliopause, which acts as a transition zone to interstellar space, on November 5. It’s now about 11 billion miles from Earth.
