NASA To Reveal New Data On Conditions At Edge Of Solar System

www.nasa.gov...

WASHINGTON -- NASA will host a media teleconference at 1 p.m. EDT, on Wednesday, Sept. 29, to discuss new information about the boundary of our solar system obtained from the agency's Interstellar Boundary Explorer (IBEX) spacecraft.

The briefing participants are:
- Arik Posner, IBEX program scientist, Heliophysics Division, Science Mission Directorate, NASA Headquarters in Washington
- Nathan Schwadron, IBEX science operations lead and associate professor at the University of New Hampshire in Durham
- David McComas, IBEX principal investigator and assistant vice president of the Space Science and Engineering Division at Southwest Research Institute in San Antonio
- Merav Opher, associate professor, George Mason University in Fairfax, Va.

Reporters can receive dial-in information by sending an email to JD Harrington at [email protected]. Requests must include reporter's name, affiliation, and telephone number.

Audio of the teleconference will be streamed live at:

At the beginning of the briefing, related images will be available online at:

Hmm, now this is curious, and I wonder what they've found...Maybe our solar system is being slowly devoured by a giant black hole! And of course we get eaten on Dec. 21, 2012, too! :shk:

Still, this will be of interest to many.

now this is somthing that could be interresting to se

The satellite itself is in Earth orbit. It has been monitoring the interactions at the edge of the Sun's magnetic field. There probably won't be anything worthy of a screaming headline, but I suspect there may be some jaw dropping false color photos.

well i dont think they will make a media teleconference just to say theres nothing there?

Magnetic Potholes, Sluggish solar wind and Anomalous Cosmic Rays.

Just a guess but I bet they will cover some of the above.

My guess is that the asteroid belt has contracted.

Our solar system is passing through a cloud of interstellar material that shouldn't be there, astronomers say. And now the decades-old Voyager spacecraft have helped solved the mystery. The cloud is called the "Local Fluff." It's about 30 light-years wide and holds a wispy mix of hydrogen and helium atoms, according to a NASA statement released today. Stars that exploded nearby, about 10 million years ago, should have crushed the Fluff or blown it away. So what's holding the Fluff in place?

A similar article:

Maybe they've found out more about the Fluff? It's worth knowing about.

It will probably be something mundane, like the outer solar system is 1/1000th degree warmer than previously thought. Although, I am hoping for something a little more interesting. Maybe a new plutoid?

OK, so what happened? Did anyone see the conference? Are there any video links? I was eagerly awaiting the ATS community input about this one.

Interstellar space weather.

"Our discovery of changes over six months in the IBEX ribbon and other neutral atoms propagating in from the edge of our solar system show that the interaction of our sun and the galaxy is amazingly dynamic," said David J. McComas, IBEX principal investigator and assistant vice president of the Space Science and Engineering Division at Southwest Research Institute in San Antonio. "These variations are taking place on remarkably short timescales."

found a impression pic for this thread




here is another 1 for your thread

As the IBEX spacecraft gathers a wealth of new information about the dynamic interactions at the edge of the solar system — the region of space that shields our solar system from the majority of galactic cosmic ray radiation — the IBEX team continues to study numerous theories about the source of the ribbon and its unusual features.

going to look into this one very interesting

i found the fact that there was a greater than expected feild strenght

Voyager data show that the Fluff is much more strongly magnetized than anyone had previously suspected—between 4 and 5 microgauss*," says Opher. "This magnetic field can provide the extra pressure required to resist destruction."

this means interstella space is energetic with energized particals in the form of light hot gasses
the exaust effect traps these gasses at higher than normal levels allowing for a greater magnetic charge potential than what was expected

how much energy is out there in the form of these concentrated pressurized heated clouds of fluffy space and is this the perfect fuel source for interstella travel using the hot gases to recharge and regas

You have it kind of backwards. The fluff is not trapped by the exhaust from the supernovas and the magnetism is not caused by it (there is no such thing as a magnetic "charge", there are only magnetic fields).

The exhaust should have dispersed or compressed the fluff. Neither one of those things happened. Because of the (relatively) high level of magnetism the fluff is able to resist the effects of the supernovas and not be compressed and not be dispersed. The fluff is not "pressurized". It would make good fuel but its temperature and magnetic properties wouldn't really make it much better than any other fuel.

that you for explaining that for me
is there a greater than normal or unexpected magnetic feild involved with this fluff?
do we know why it is resistant to compresion and what sort of density does it have?
is this cloud like plasma where it can carry an electrical charge?
what effect does the heliosheth show from interaction with this fluff?

i thank you in advance as i try to find these answers

i found some interesting this here

The solar wind blows an immense magnetic bubble, the heliosphere, in the local interstellar medium (mostly neutral gas) flowing by the Sun1. Recent measurements by Voyager 2 across the termination shock, where the solar wind is slowed to subsonic speeds before entering the heliosheath, found that the shocked solar wind plasma2 contains only ~20 per cent of the energy released by the termination shock, whereas energetic particles3 above ~28 keV contain only ~10 per cent; ~70 per cent of the energy is unaccounted for, leading to speculation2, 3 that the unmeasured pickup ions or energetic particles below 28 keV contain the missing energy.

i am having trouble with the explanation from the ibex satalite of this photo




is this a charged eddy current at the helio shock and is it unraveling?

so its the unexpected thing holding the fluff together is the strongly magnatized nature of the gas mixtures

The Fluff is completely surrounded by this high-pressure supernova exhaust and should be crushed or dispersed by it.
"The observed temperature and density of the local cloud do not provide enough pressure to resist the 'crushing action' of the hot gas around it," says Opher.

here is more info on the knot interacting with the heliosphere

San Antonio — Sept. 29, 2010 — The unusual "knot" in the bright, narrow ribbon of neutral atoms emanating in from the boundary between our solar system and interstellar space appears to have "untied," according to a paper published online in the Journal of Geophysical Research.

link for solar system ribbon info

so neutral atoms are entering our helio sphere have linked up with other neutral atoms also in the form of a "ribbon" across the helio sphere

Analyses of the first map, released last fall, suggest the ribbon is somehow ordered by the direction of the local interstellar magnetic field outside the heliosphere,

so could the magnetic force suspected of holding the fluff together outside the helio sheath have some effect on the ribbon of neutral atoms ?
