NASA's Voyager 2 space probe entered interstellar space last year, repeating the achievement of the Voyager 1 spacecraft.
The scientific journal Nature Astronomy published a series of articles this week analyzing messages from the Voyager 2 probe since its launch into interstellar space at a distance of 18 billion kilometers from Earth in November 2018.
They describe Voyager 2's journey, including its passage through the heliopause (the part of the solar system exposed to particles and ions from deep space) and the helioshis (the region of the heliosphere beyond the shock wave) to what is beyond the universe.
The spacecraft will be able to send data about its journey to Earth in the future. Both probes - Voyager 1 and Voyager 2 - continue to make measurements in interstellar space during the flight, but they are expected to have enough energy to operate only for the next five years or so. No further missions to interstellar space are currently planned by NASA.
