Voyager-1 beams back data from interstellar space, Nasa new density measurements make waves
A representative image of Voyager-1 travelling through interstellar space. (Source: Nasa) When Voyager-1 was launched on September 5, 1977, the team that worked on the probe had no idea that even after four decades, the spacecraft would still be sending critical data pings and that too from beyond the Solar System. Now in interstellar space, the area beyond the magnetic bubble inflated by our Sun, Voyager's data is revealing what that new frontier is like. A study published in Nature Astronomy reports what may be the first continuous measurement of the density of material in interstellar spac...
