Voyager Probes: Breaking Through the Solar System's Firewall
2025-06-23
Launched in 1977, Voyager 1 and 2 have journeyed for decades, eventually breaching the Solar System's 'firewall' – the heliopause. Temperatures there reach 30,000-50,000 Kelvin, yet the probes survived due to the low particle density. Data confirms the heliopause isn't a rigid boundary, shifting with solar activity. Surprisingly, the magnetic field beyond is parallel to the inner heliosphere's field, a discovery defying prior assumptions. Voyagers continue transmitting invaluable data, offering unprecedented insights into interstellar space.
