Voyager 1 — Heliopause | Boundary Crossing Electronic | 航海家1號：日球層頂 | Gravity Wave Radio | 引力波段

"There was no visible line in the dark. It only knew it had crossed into the interstellar ocean when the sun's wind finally died." On August 25, 2012, Voyager 1 became the first human-made object to cross the heliopause—the invisible frontier where the hot plasma of the solar wind meets the cold, dense material of interstellar space. The crossing was not marked by alarms or sudden flashes; it was silent and formless. Scientists only confirmed the historic exit months later by meticulously analyzing changes in electron density data. Copyright & Terms of Use: © 2026 Gravity Wave Radio. All rights reserved.
