Some changes are being observed in the boundaries of the solar system.
These changes are observed upon detecting the presence of wave structures there.
This information is obtained from data from NASA’s Interstellar Boundary Explorer.

The boundary of our solar system is a very important place. Here the influence of the solar wind begins to fade and the influence of space rays and interstellar material begins to dominate. The bubble inside the region that contains the solar system is called the heliosphere and the boundary region is called the heliopause. Data from NASA’s Interstellar Boundary Explorer spacecraft orbiting Earth has revealed that the heliopause and its surroundings are changing over time, causing the heliosphere to contract at times.

Can learn a lot.
Data from this study revealed the presence of wave structures in the heliopause and surrounding islands. These results suggest that a detailed picture of the solar system’s size can be obtained and changes over time can also be detected.

Ionized plasma flow
Heliosphere protects the solar system and its surrounding area from celestial radiation. The Sun affects its surroundings in many ways, including the solar wind, a continuous supersonic flow of ionized plasma. They go beyond the planets and the Kuiper Belt into interstellar space. The point at which the speed of this flow in the interstellar medium becomes less than the speed of sound. This is called termination shock.

Where this medium is not in a position to push back the plasma flow at all, the heliopause occurs. Scientists have found wave structures between the termination shock and the heliopause. Interestingly, both of NASA’s Voyager missions have crossed the heliopause and are also reporting from interstellar space about this changing boundary. But NASA’s Interstellar Boundary Explorer is proving to be another tool.
