NASA’s Voyager 1 discovers a fiery hot zone in space — but there’s no fire! What’s going on?

NASA’s Voyager 1, launched in 1977, has detected an unexpected hot and energetic “firewall” just beyond the heliopause, challenging previous assumptions about the solar system’s edge. The spacecraft’s data reveals surprisingly high particle temperatures and a magnetic connection between our solar system and interstellar space. These findings prompt a reevaluation of the boundary’s complexity and the Sun’s influence.
