I noticed a lot of filaments going in different directions in this photo. I wonder what these are?

Hello Orin

also see link http://antwrp.gsfc.nasa.gov/apod/ap040408.html

as for the filaments

I think they are plasma matter

see link for maybe a similarity.

http://antwrp.gsfc.nasa.gov/apod/ap050403.html
the Arches have their geometry because they contain hot plasma flowing along lines of constant magnetic field. Recent images from the Chandra X-ray Observatory appear to show this plasma colliding with a nearby cloud of cold gas

The filaments look like they make there own light; I mean they don't look like they are lit up from reflections from the stars. Would plasma do this? How do you define plasma? I thought plasma was a fourth state of matter.

Hello Harry! Maybe your right. I found this about plasma;
http://www.plasmacoalition.org/what.htm
If the filaments are plasma them I'm guessing that they would be highly energetic. Be interesting to be able to view up close.

hi orin,
i suspect we are seeing 'ridges' in the dust that are illuminated by nearby stars, and since the colours in this picture are fake they have probably been exaggerated to the point where they look like they are self lit. I dont know of any other mechanism which could explain it... it could be an hydrogen emission nebula (and that is the same as a plasma is it not? ionized gas?) but it would still need an energy source to become ionised and that would be the nearby stars

Hello All

Yes Plasma in one form is ionized gas but not limited to it.

see orins link
http://www.plasmacoalition.org/what.htm
Thus the term "plasma" was first used to describe partially (if not weakly) ionized gases. The term plasma apparently did not find immediate widespread use in the scientific community. It did eventually catch on, however, but in some cases the term was inappropriately limited to highly ionized gases.
see links
http://columbia-physics.net/faculty/gyulassy_main.htm
I head the nuclear theory group at Columbia. Our work concentrates on the physics of ultra-dense nuclear matter, called the quark-gluon plasma.
http://plasmadictionary.llnl.gov/
http://www.plasmas.org/fusion-icf.htm

this one orin
http://www.plasmas.org/space-astrophys.htm
Plasmas are a combination of neutrals, ions, electrons and fields that have conductive and collective effects and where interparticle dynamics is not dominated simply by binary collisions. This condition applies for most astrophysical systems. Even though space plasmas usually maintain quasi-neutrality to within less than about 1 part per million, there can still be substantial currents, convection, plasma flows, plasma waves and shocks and other plasma effects that interconnect plasmas over vast expanse as demonstrated by direct measurements of solar system space plasmas. Radio jets, interstellar shocks, stellar systems (especially neutron stars), and many astrophysical phenomena now appear to involve important plasma effects.



other info on plasma, this study on Plasma is the cutting edge to reslove the ongoing of the universe.

I liked this Harry;

This nebula has a lot of filaments also. Almost like lightning; only different.

Hello Orin

I thought you would like it.

For 30 odd years I have been discussing plasma as other than ionized atoms and scientists were putting me out to dry. In the last decade or so people are placing more value to plasma matter and its importance in star formation, galaxy formation and blackhole evolution.

The crab nebula is loaded with filaments.

Hello All

Hello Orin,,,,,,,,,,thank you for the link, its amazing 20 years ago this was just a dream. The observations that we are able to see is out of this world, so to speak.



The filaments remind me of the brain nerve cells.

The filaments run along some magnetic field and for a matrix.

Hello All

More on filaments
http://www.cfht.hawaii.edu/News/Lensing/#IC
The dark matter is concentrated into a web-like distribution of filaments that intersect at dense nodes where great clusters of galaxies are expected to form and become visible.

I have more but! unable to use my comp,,,,,,,,,,,,,,darn thing

I was of the understanding that filaments like these in supernova remnants were areas where the hot, fast-moving gases of the actual remnant were impacting dense regions in the cooler, slower-moving surrounding interstellar gases. This would cause the gases to ionize, then recombine, emitting light.

Yep


Does that make it the shortest response?

I marvel at the length of these filaments. The jellyfish nebula is 65 light years across. Some of these filaments must be over a light year long.

Hello

Could this be a filament
http://antwrp.gsfc.nasa.gov/apod/ap010905.html
Shooting out from 3C175 is a thin jet of protons and electrons traveling near the speed of light that is over one million light-years long
and the filament around this tornado jet

http://antwrp.gsfc.nasa.gov/apod/ap060203.html

from the galactic centre,,,,,,,,,,I have posted this before
http://antwrp.gsfc.nasa.gov/apod/ap050403.html

http://chandra.harvard.edu/photo/2002/g ... index.html
The X-ray emission is thought to be produced when energetic electrons from the radio filaments collide with the cold gas cloud, which has a mass one million times the mass of the Sun. This process of the bombardment of cold gas clouds with energetic electrons could explain the origin of the mysterious X-ray ridge along the plane of the galaxy that was discovered nearly 30 years ago.

I believe it is more of a jet stream. Still the lenght of it is amazingly long.

Hello Orin


Your right.
http://antwrp.gsfc.nasa.gov/apod/ap010905.html
Shooting out from 3C175 is a thin jet of protons and electrons traveling near the speed of light that is over one million light-years long. The jet acts like a particle cannon and bores through gas cloud in its path. How this jet forms and why it is so narrow remain topics of current research.
http://adsabs.harvard.edu/cgi-bin/nph-b ... .511...84H
We conclude that our results are generally consistent with a fairly simple relativistic jet model and with the unification of core-dominated quasars, lobe-dominated quasars, and possibly even powerful radio galaxies; there is a marginal suggestion that the quasars in our samples have a restricted range of angles to the line of sight (e.g., 0 deg to ~45 deg).

Some of these have pretty good filaments; especially the Cygnus Loop and the Veil Nebula. The Crab Nebula also has a good amount of these.

The plasma filaments shown in a lot of these photographs make a great show uncovered by astronomy. They also show great artwork that is all natural. there is also a lot of energy and beauty in the universe.

Hello Orin


Plasma Cosmology is heading to become the main theme in the ongoing of the Universe.

If you noticed I did not say the Origin of the Universe.

Is this what you mean Harry?

Sounds interesting; but isn't there a shortage of antimatter to make it work?

Hello Orin

What is matter and anti-matter?

Ultra dense matter is a combination of left and right spins of the basic particals that make up atoms.

Anti matter refers to normally to normal matter as we see it and anti-matter having a reverse in charge per partical.



But! Plasma cosmology has been around for decades.

It is one field worth keeping track.
