NASA | IBEX: Exploring The Edge Of Our Solar System

IBEX is a new NASA mission that will study the interaction between the solar wind and the material beyond our solar system called the interstellar medium. The solar wind flowing out from the sun inflates a bubble that we call the heliosphere. IBEX's job is to study those boundaries and understand how they really work and tell us how the heliosphere is able to do the important job of protecting us from the dangerous galactic cosmic rays.
