I hadn't heard this, and it's actually pretty cool. We don't know a huge amount about the space just outside the solar system, and the Voyager probes are close enough to the edge to see this. As other probes get out there we'll learn even more -- New Horizons is screaming out that way even now. Cool.

"physics says should not exist"

aka - we didn't notice we were headed straigt towards it and then holy shiit we're in it!

Is this nature's version of a shielded, manned interstellar spacecraft, with DNA cargo and water on Earth, gas on Jupiter, the sun used for active shielding and life support?

And that has dick to do with shiat.

This is pretty interesting, actually. I wonder why it's so magnetized?

Neato. Those Voyager probes are amazing achievements.

Just a run of the mill class 3 nebula. It's not like there's a Borg transwarp hub in there.

From what I read, New Horizons is never going to catch any of the original interplanetary probes, although we'll probably be in good telemetry contact with it for much longer.

Is it possible to be magnetised without being electricated?

Sorry. I so thoughroughly don't understand fields at all, and it truly bugs me.

The Voyagers may be the biggest scientific bang for the buck in history. They are close to fifty years old and still phone home with info that revolutionizes science.

Man, the Voyagers are freakin' awesome. I hope I'm around to see the day they send probes to another solar system. Even if I'm not around to see the data they collect just knowing they're on their way will make me very, very happy.

This needed to be posted. First thing I thought of from the headline.

6000C? THat's kind of hot...I take it that, at the low densities of the cloud in question, it's "just" a measurement of how fast the atoms are moving and not indicative of turning Voyager into a molten blob.

FTFA:

...that physics says should not exist.

This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all


Then physics says it should exist. Nobody breaks the laws of physics. NOBODY!

Bevets: Russell Humphreys predicted the Pioneer Anomaly four years before it became public knowledge.

Really? I'm not sure I believe your statement, because you didn't link to a peer reviewed article where he accurately predicts the Pioneer anomaly, within a reasonable percentage of accuracy.

Just saying "something funny might happen" isn't a prediction.

A prediction is telling someone that if they jump off the building, then 3 seconds later they will smash into the concrete, forcing the body to absorb almost 45,000 joules worth of energy, thereby causing major damage to that body, and most probably killing the person who jumped.

On the other hand, it's very lucky that he really didn't predict this. Otherwise you would have to turn him in to religious authorities for stoning, the way Leviticus says you should. (Leviticus 20:27)

Are there fluffers in the fluff cloud?
 
2009-12-24 10:30:19 AM
Would be nice to see a drawing of the Local Fluff to scale with the outer solar system. The Voyagers are out beyond the orbit of Pluto, but they're still within the range of the Kuiper Belt and there's enough out there - not to mention the Oort cloud - that this stuff should interact with it too...

I wonder if there's enough mass in the cloud to affect the orbits of bodies in the extended solar system...

What were the skies like when you were young?

They went on forever
And they -- when I
We lived in Arizona
And the skies always had little fluffy clouds
And they were long and clear
And there were lots of stars, at night
And when it rained it would all turn
It -- they were beautiful
The most beautiful skies as a matter of fact
The sunsets were purple and red
And yellow and on fire
And the clouds would catch the colors everywhere
That's -- it's neat
Because I used to look at them all the time
When I was little
You don't see that

Layering different sounds on top of each other
Layering different sounds on top of each other

Little fluffy clouds
Little fluffy clouds and
Little fluffy clouds and
Little fluffy clouds and

You don't see that

You might still see them in the desert

The most beautiful skies as a matter of fact
Purple and red
Purple and red and yellow and on fire

I'm more amazed at the fact that the Voyager probes are still transmitting relevant data. :D Apparently both are set to lose complete power in 2025.

Interesting, question for the physicists, could outside sources like this cause ice ages?
If the heliosphere is pressured from outside sources, does that mean that the sun would a)feel the magnetic pressure and produce less electromagnetic energy/light/heat b)could there be a "solar greenhouse effect as an infinitesimal amount of energy over a massive scale encounters resistance and reflects back (or behaves in a unpredictable manner on a large scale) sort of like a solar pressure cooker, c)we enter a nebula and all die of alcohol poisoning if the oort cloud didnt soak it all up. or d)nothing, we dont know, could have happened many times before in the last 10,000 years, we didnt have the tools to record infomation back then, but this is no excuse to dabble in pseudoscience???

I'm not a physicist (yet), just a physics undergrad, but it makes sense that it would be magnetized. At 6000 C, the many atoms are almost certainly ionized. A magnetic field is created by moving electric charge, and a hydrogen nucleus without its electron has an electric charge.

At least that's what I think is happening here. I could be way off base.

Can anyone give a theory as to how a cloud of (possibly ionized X)can reach 6000 degrees celsius in a vacumn and not be a problem. Or just explain why?

Its leviticus's like you that hurt the world. You quote Newton, and love the fact that you really understand why a cat in box does and doesn't exist. No, this isn't an attack, I know you GET it. For the official record, a prediction is a before reading, or before reading, or even a before telling people what to hear. But we know how the world is..... I think you overlooked a few thing, or at least i hoped you did.

Im drunk, I apologize. I dont even know if im gay or not. And i live in London. But Im very interested in this, and i'd love to hear some theories.
