Did you know that a “Magnetic Bubble” Protects Entire Solar System As We Cruise The Universe! NASA’s IBEX Measures Heliosheath Vs. “Magnetic Bubble” Surrounding Our Solar System. It’s an alien environment out there: the material in that galactic wind doesn’t look like the same stuff our solar system is made of says NASA, “A great magnetic bubble surrounds the solar system as it cruises through the galaxy.
Sun pumps the inside of the bubble
The sun pumps the inside of the bubble full of solar particles that stream out to the edge until they collide with the material that fills the rest of the galaxy, at a complex boundary called the heliosheath. On the other side of the boundary, electrically charged particles from the galactic wind blow by, but rebound off the heliosheath, never to enter the solar system. Neutral particles, on the other hand, are a different story. They saunter across the boundary as if it weren’t there, continuing on another 7.5 billion miles for 30 years until they get caught by the sun’s gravity, and sling shot around the star.
There, NASA’s Interstellar Boundary Explorer lies in wait for them. Known as IBEX for short, this spacecraft methodically measures these samples of the mysterious neighborhood beyond our home. IBEX scans the entire sky once a year, and every February, its instruments point in the correct direction to intercept incoming neutral atoms.
More than just helping to determine the distribution of elements in the galactic wind, these new measurements give clues about how and where our solar system formed, the forces that physically shape our solar system, and even the history of other stars in the Milky Way.”
