It sounds kind of delicious the way they describe it but NASA has discovered a mysterious cluster of "frothy magnetic bubbles" at the edge of our solar system. Discovered by probes Voyager 1 and Voyager 2 the bubbles are in the 'foam zone" or heliosheath. Scientists now have a few theories on what the bubbles are or may do. Sadly none of them are that the solar styem is one giant milk shake.
The simplest way to describe what both probes are currently travelling through is as a grouping of frothy magnetic bubbles. NASA is also referring to the area as the “foam zone.” The bubbles are not small, with each measuring around 100 million miles wide.
The foam zone was entered in 2007 by Voyager 1 and 2008 by Voyager 2. The reason we are only now hearing the details is because scientists had no idea what it was both probes were travelling through. A couple of years later and NASA believe they have worked it out.
