Only 2 Probes Ever Left the Solar System: Voyager vs the Heliopause #space #shorts Description: The Solar System doesn’t really “end” at Pluto. It ends where the Sun’s magnetic bubble finally gives way to interstellar space: the heliopause, over 18 billion km away. Only Voyager 1 and Voyager 2 have ever crossed this boundary, after more than 30 years of travel. This short explains what the heliosphere is and why crossing it was such a huge milestone. #voyager #nasa #solarsystem #heliopause #heli
