NASA's Voyager Detects Hot 'Wall' at Solar System's Edge Linked to 1977 Wow! Signal
NASA's Voyager spacecraft discovered a 'wall of fire' at the edge of the solar system, with temperatures between 30,000 and 50,000 Kelvin, as they crossed the heliopause, marking the boundary where the solar wind meets interstellar space. Despite the extreme temperatures, the probes survived due to the sparse particle environment, providing valuable data about the solar system's outer limits and magnetic field alignment beyond the heliosphere.
