The heliopause is an invisible boundary approximately 11 billion miles from Earth where the Sun's solar wind collides with the cold, high-pressure radiation of interstellar space, causing temperatures to spike by tens of thousands of degrees; this 'Wall of Fire' marks the edge of our Sun's protective bubble, beyond which stars become sources of lethal unshielded energy, and only two human-made objects—Voyager 1 and Voyager 2—have ever crossed this frontier into the deep void of the galaxy.

The Wall at the Edge of the World | Earth’s Invisible Border! 🛰️🔥Added:
Most people think our solar system just fades away into nothing.
But there is actually a wall out there.
It's called the heliopause, a violent invisible boundary where the sun's solar wind slams into the cold high-pressure radiation of interstellar space.
11 billion miles away, the temperature jumps by tens of thousands of degrees.
This is the great repulse, where our sun's protection finally fails, and the true vacuum of the galaxy begins.
Only two human-made objects have ever crossed it. Beyond this wall, the stars aren't just points of light. They are sources of lethal unshielded energy. We are living inside a fragile bubble in a very dangerous neighborhood. This is the loneliest border in existence. Would you dare to cross the boundary into the deep void?
