NASA’s long-lived Voyager 2 probe, still sending back data 41 years after launch in 1977, has finally moved into interstellar space, joining Voyager 1 in the void between the stars.

Are we there yet? Voyager 2 nears the boundary of interstellar space

Six years after the Voyager 1 spacecraft moved into interstellar space, Voyager 2 is detecting an increase in cosmic ray strikes indicating the probe is nearing the edge of the protective bubble defined by the Sun’s influence.

NASA’s IBEX observations pin down interstellar magnetic field
