After 50 years of silence, Voyager 2 has finally spoken back from the dark—but it isn’t sending data. Scientists have discovered a precise, rhythmic, and intelligent signal buried in the static that is definitely not from Earth.  Even more terrifying, they’ve realized something is moving alongside the spacecraft in the deep void. It isn’t drifting or orbiting; it is tracking us. Our oldest machine has finally reflected a truth we can no longer deny: we are not alone.
