Voyagers Find Giant Jacuzzi-like Bubbles at Edge of Solar System
These 30 year old machines keep pumping out discoveries...
The barrier at the edge of our solar system may not be the smooth shield that scientists once thought. The venerable Voyager spacecraft have detected a huge, turbulent sea of magnetic bubbles in the heliosheath — the interface between the heliosphere and interstellar space — similar to an actively bubbling Jacuzzi tub. At a briefing today, scientists said the finding is significant as “we now will have to change our view of how the sun interacts with the solar system,” said Arik Posner, Voyager program scientist at NASA Headquarters. But it also means that the “force field” that surrounds the entire solar system may be letting in more harmful cosmic rays and energetic particles than previously thought.
