This Is What Is At The Edge Of The Solar System

Technology is disclosing a new fact to us. Even, a few years back, it was almost impossible to map the edge of the solar system. But with the help of technology, scientists have recently mapped the edge of this solar system that is highly violent in nature. They used an echolocation-like process for doing this.

The edge of the solar system is very violent in nature with two different cosmic powers clashing. On the inward side of this frontier, you will see the constant movement of hot, charged particles flowing outward from the sun at a rapid speed—almost a hundred miles per second. On the outward side of this frontier, a space wind originating from nearby stars collides head-on with the solar wind.

Several studies have revealed that almost 2,600 years ago, a gigantic solar storm hit the surface of the earth. It was almost 10x stronger than any solar storm that has hit Earth in modern times. Despite the fact that solar storms cause episodic blackouts on our planet, the solar wind typically protects our planet from interstellar radiation. Research shows that the solar wind blows out from the sun in every direction. Thus, it is creating a protective bubble around the entire solar system—a bubble that is repelling almost 70% of the incoming radiation.

This bubble is called the heliosphere, and its outer edge is called the heliopause, the border between interstellar space and the solar system. It is the place where the solar system actually ends and interstellar space begins.

There are many borders on our planet and scientists know how big they are. But, this does not happen in the case of the heliosphere. Scientists do not know how big this border is. They do not even know how it looks. However, The Astrophysical Journal made a 3D map of this border. This is was a great accomplishment. They used data that had been captured for 10 years by NASA. They studied the path of the solar-wind. These hot, charged particles actually travel from the sun to the edge of the solar system, and then, they go back again. On the basis of this discovery, scientists created a 3D map.

These discoveries have revolutionized our understanding of the solar system and its outer regions.
