About this listen

Launched in 1977, Voyager 1 has traveled farther than any human-made object in history—and what it discovered at the edge of our solar system reshaped our understanding of space. In this episode, we explore Voyager 1’s historic journey beyond the planets and into interstellar space, explaining what it actually detected as it crossed the heliopause—the boundary between the Sun’s influence and the wider galaxy.
We break down the strange changes in cosmic radiation, magnetic fields, and charged particles that confirmed Voyager 1 had truly left the solar system. You’ll also learn what the spacecraft revealed about the solar wind, how scientists know it’s now in interstellar space, and why Voyager’s instruments are still sending valuable data decades later.
A fascinating look at humanity’s most distant messenger—and what lies beyond the protective bubble of our Sun.
