NASA’s Voyager 2 has become the second human-made object to enter interstellar space, the government agency announced this week.
Now 11 billion miles from Earth, the probe crossed the outer edge of the heliosphere on November 5, which acts as a transition zone to outer space.
Though NASA’s Voyager 1 managed the same feat in 2012, its instrument to gather plasma data was damaged in the 1980s, while Voyager 2 has been able to communicate data from its journey through the edge of the solar system.
