Interstellar Gas Interactions with the Heliosphere's Magnetic Boundary
Quick fact
Neutral hydrogen atoms from interstellar clouds can sail right through the heliosphere's magnetic boundary, while charged particles are deflected—creating a fascinating interplay that shapes the heliosphere's outer edge.
Why this is interesting
Our Sun is not just drifting through empty space—it is pushing a giant magnetic bubble through clouds of interstellar gas. How does that gas interact with the bubble's edge?
