by Astronomers using NASA’s Interstellar Boundary Explorer (IBEX) satellite have mapped the boundary of the heliosphere, the vast region of space surrounding the Solar System that is filled with the solar wind.
The Earth-orbiting IBEX satellite detects particles that come from the heliosheath, the boundary layer between the Solar System and interstellar space.
Dr. Dan Reisenfeld from Los Alamos National Laboratory and colleagues used IBEX data to map the edge of this zone — a region called the heliopause.
Here, the solar wind, which pushes out toward interstellar space, collides with the interstellar wind, which pushes in towards the Sun.
