Voyager Probes Detect Plasma 'Firewall' at Heliopause, Temperatures Reach 50,000 K

NASA's Voyager 1 and 2, operational since 1977, have detected a plasma 'firewall' at the edge of the heliosphere, with temperatures up to 50,000 Kelvin. This finding challenges existing models of the heliopause boundary and provides new data on interstellar medium interactions. The discovery is significant for understanding the solar system's outer limits, though details remain preliminary.
