  1. Time to let out my inner nerd…

    Ok, so the sun gives off a lot of energy. A LOT. The force of that energy streaming away from the sun creates a wind. The wind only blows so far, then it stops. Kinda like a balloon, the contents are kept within certain boundaries, except the boundaries are not defined by latex (the boundary is just where the pressure from energy released from the sun meets the pressure from the outside universe). The technical word for this balloon is the heliosphere. It contains our solar system and is pretty important in making sure we don’t get blown away into cosmic dust. Anyway, their little space craft crossed this boundary and learned that it is not a smooth, even boundary; it’s dented. So there you have it: the balloon has dents.

    PS This entire article presumes that our universe was formed by the Big Bang. The heliosphere is pushing back against the forces of our expanding universe (or is it shrinking again?) to create a bubble of relative calm in the tempestuous sea of our cosmos…

    If you don’t believe in Big Bang, maybe it’s just God’s saran wrap on top of his experiment and we should quit poking holes in it?

  2. Intriguing. That’s a little easier for me to understand. The one thing I don’t get is that my geography textbook teaches me that the heliosphere is part of our biosphere (you know, of Earth). So is heliosphere just a type of thing, like dirt or water?

    Thanks for the explanation!

  3. I don’t know anything about the heliosphere being a part of our biosphere. Of course, we are IN the heliosphere, as is the rest of our solar system…
