Ribbon

[tansy]

Anyone any thoughts on this? Do you think earth could be in danger of losing protection from radiation?

Oops sorry, link didnt seem to work properly. Anyhow it was on Spaceweather and about a puzzling ribbon which scientists think, if I read it right, helps deflect radiation from the earth

This? NASA - Giant Ribbon at the Edge of the Solar System: Mystery Solved?

January 15, 2010:

Last year, when NASA's IBEX (Interstellar Boundary Explorer) spacecraft discovered a giant ribbon at the edge of the solar system, researchers were mystified. They called it a "shocking result" and puzzled over its origin.

[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]Now the mystery may have been solved.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]http://science.nasa.gov/headlines/y2010/images/ibex2/ibex.jpg"We believe the ribbon is a reflection," says Jacob Heerikhuisen, a NASA Heliophysics Guest Investigator from the University of Alabama in Huntsville. "It is where solar wind particles heading out into interstellar space are reflected back into the solar system by a galactic magnetic field."[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Heerikhuisen is the lead author of a paper reporting the results in the Jan. 10th edition of the Astrophysical Journal Letters.

Yeah, the idea of something that can interact with the solar protection (the ribbon isn't protective itself, it's just a result of the solar and galactic fields interacting) we get on that level is....interesting. Then again, we're small fry on a galactic scale, so it stands to reason that we'd find something on a bigger scale interacting with our solar system.

I suspect however that we're probably a lot more likely to get shafted by our own sun when it has a rough day than the galactic field. Then again, I don't know anything about how variable galactic fields are so someone else might have to comment on that one.

On the plus side, if we do suddenly get baked by cosmic radiation at any point on the future we'll at least have some lovely aurorae to see before our eyeballs melt.

Yes, thanks, that was the info I wanted to link to.

Wonder if we'd see the aurorae in more southerly regions though LOL

We wrap gifts in ribbons don't we?

We wrap gifts in ribbons don't we?

sometimes i go nuts and wrap gifts in not only ribbons but magnetic fields also

it's the thought that counts

Trouble is, depending on the gift, mightn't the magnetic field ruin the gift?
