the changes in the size of our solar system's boundaries also cause changes to the galactic cosmic rays that enter the solar system. although these boundaries do a good job of deflecting the majority of harmful galactic radiation, some fraction of this galactic radiation always makes it into the solar system. the boundaries surrounding our heliosphere can change both due to changes in our galactic environment and through changes in the solar wind emitted by the sun. we see here an animation of the boundaries surrounding our solar system falling in and then expanding. these changes in our heliosphere must have happened in the past and will likely occur in the future. the ibex science team compares the first and second maps to reveal whether there are time variations in the ribbon or the more distributed emissions around the ribbon. this animation fades between the first and second ibex maps. we see that the first and second maps are relatively similar. however, there are significant time variations as well. the heliosphere deflects galactic cosmic rays from entering the system. galactic cosmic rays are a very high energy form of particle radiation that are extremely difficult to shield against and are harmful to astronauts. the boundaries surrounding our heliosphere deflect the majority of galactic radiation from the inner solar system. the heliosphere is a bubble that surrounds our entire solar system and is inflated by the outward solar wind, which pushes out and ltbgt...lt bgt
