A spacecraft launched in 1977 has just sent back its first data from interstellar space.
Voyager 2 finally exited our solar system in 2018. Entering what’s called the heliopause.
NewScientist.com reports it’s only the second spacecraft to leave our solar system. Voyager 1 did that in 2012.
Both spacecraft are still sending back data; however, their power will run out within the next five years.
