What is the Heliosphere?
The Heliosphere is an enormous region of space that surrounds our solar system, created by the solar wind, which is a continuous flow of charged particles emitted by the sun. This vast bubble stretches far beyond the orbit of Neptune, encompassing the planets and their moons, and extends up to about 100 astronomical units (AU) from the sun. It serves as a protective shield against cosmic rays, which are high-energy particles from outside our solar system.
Structure of the Heliosphere
The Heliosphere is composed of several distinct zones. At its center lies the solar wind, surrounded by a boundary known as the heliopause. This boundary marks the point where the solar wind’s strength is equal to the interstellar medium’s pressure. Beyond the heliopause is the interstellar space, where the influence of the solar system begins to wane.
Importance of the Heliosphere
