Mother Earth

Earth is protected from harmful radiation from the Sun by it's hard metal core that produces a strong magnetic field. As we orbit the sun, there is a bow wave of pressure that forces cosmic rays and heavier atomic particles around the little planet we live on. Without it, everything on Earth would die.

The Interstellar Boundary Explorer (IBEX) mission has located a mysterious ribbon of energy that surrounds the solar system and protects us further from galactic and cosmic rays originating outside of the solar system.

LINK HERE "The finding, which overturns 40 years of theory, provides insight into the fundamental structure of the heliosphere, which in turn helps scientists understand similar structures or "astrospheres" that surround other star systems throughout the cosmos.
"The ribbon of energy was captured using ultra-high sensitive cameras that image energetic neutral atoms (instead of photons of light) to create maps of the boundary region between our solar system and the rest of our galaxy."

the heliosphere -- the huge bubble that surrounds our solar system 
and protects us from galactic cosmic rays.

I don't know how many planets like ours are out there. Without tectonic plates, there would be no dry land (no mountains), without liquid water, there would be no life, without a solid iron core there would be no magnetic field, and on - and on. I refer you to the linked article above for an interesting journey into the mechanisms that exist to protect fragile life on the Third Rock from the Sun.

  1. Cool! The coil structure reminds me of induction coils used for capture and storage of electromagnetic fields (see interloping rings in the figure).

  2. Chickelit - that an 'induction coil' in space would form is nothing short of amazing. I had the same feel but I thought people would consider me the other side of sane.

  3. It would be fun to boldly go there.

  4. Opus - I think there was a Star Trek movie about a cosmic thread. I'm not sure which one it was.

  5. It's hard to imagine how one can see all these unbelievable coincidences and not think some kind of intelligent design is at play.

  6. I'm so confused ... I thought Obama protected us from everything bad in the universe.

    I love it. I'm a science nut too.

  7. Good post and good links! There is SO MUCH we still don't know...

  8. As I've heard some astronomers put it: "The universe is not a very nice place." Then again there is a lot of evidence that life can exists in the most extreme of conditions. Intelligent life? Not so much. We're still looking for that.

  9. Euripides - Will we every find intelligent life on Earth?

    NFO - Amen, brother.

    Odie - Just keep the Obama hope and change mantra going and the state will cradle you in its python-like embrace.

    Trestin - I'm with you. The word "elegant" doesn't begin to describe it.

It's virtual - it's a mirage - it's life
