missions have yielded many surprising discoveries about our solar system and, despite being 9 billion miles away from Earth, the data continues to pour in. Now, scientists at NASA
are saying that they have made sense of some surprising readings from the spacecraft over the past few years. Their data indicates that the edge of the solar system is a frothy stew of magnetic bubbles
For years it was assumed that the heliosheath
, the outer limit of our sun's magnetic field and the boarder of galactic space, was composed of graceful arcs of magnetic energy that curved back toward the sun. The reality is far less neat and tidy. Instead of arcs, the magnetic field is broken into a membrane of distinct bubbles, each about 100 million miles wide. The whole mix is also apparently writhing around, its movement being compared to bubbles from a jacuzzi jet.
Don't worry, if none of this makes any sense, there's a soothing and explanatory video at the end of this post. With pictures!
