In 1977, NASA launched Voyagers 1 and 2 to explore the outer Solar System. Nearly 50 years later, they’ve detected a “wall of fire” — a superheated plasma zone (54,000–90,000 °F) at the heliopause, where the Sun’s influence ends. This persistent feature, measured by both probes years apart, is reshaping our understanding of the Solar System’s boundary and its connection to the galaxy.
