Scientists find "ribbon" surrounding solar system

A very interesting story about the outer edges of our solar system.

In a discovery that took astronomers by surprise, the first full-sky map of the solar system's edge—more than 9 billion miles (15 billion kilometers) away—has revealed a bright "ribbon" of atoms called ENAs.

The solar system is surrounded by a protective "bubble" called the heliosphere.

Scientists have no idea why this is there -- it took them completely by surprise.

I have to say, astronomy is a very interesting science. If I was a lot smarter, maybe I would have went into it.
