The edge of our solar system is filled with a turbulent sea of magnetic bubbles, according to new NASA research.
Scientists made the discovery by using a new computer model, which is based on data from NASA's twinVoyager probes. The unmanned Voyager 1 and Voyager 2, which launched in 1977, are plying the outer reaches of our solar system, a region known as the heliosheath.
The new discovery suggests that researchers will need to revise their views about the solar system's edge, NASA officials said. A more detailed picture of this region is key to our understanding of how fast-moving particles known as cosmic rays are spawned, and how they reach near-Earth space.
Voyager 1 is now about 11 billion miles (17.7 billion kilometers) from Earth, while Voyager 2 is about 9 billion miles (14.5 billion km) away. Voyager 1 is the most far-flung human-made object in the universe.
