Kinh ngạc! Phát hiện 'bức tường lửa' nóng 50.000 độ C ở rìa hệ Mặt Trời

NASA's Voyager 1 and 2 probes have discovered a \"firewall\" of superheated plasma at the edge of the solar system. This region, where solar winds collide with the interstellar medium, reaches temperatures of nearly 50,000 Kelvin, revealing that the boundary of our solar system is a dynamic, energetic zone rather than an empty void.
