A Symmetrical Cosmic Red Square

Posted by kdawson on Sun Apr 15, 2007 03:00 PM
from the dyson-square dept.
Remember the hexagon surrounding Saturn's north pole? Now for our delectation Ano_Nimass Coward sends us to Space.com for a look at a nebula with near perfect bilateral symmetry surrounding a dying star. The so-called Red Square ranks among the most symmetrical objects ever observed by scientists. "If you fold things across the principle diagonal axis, you get an almost perfect reflection symmetry," said the leader of a study of the object, recently published in Science. A possible explanation for the structure's glow, if not its shape, was advanced in a paper appearing in PNAS, which attributes the glow of a similar object — dubbed, confusingly, the Red Rectangle — to exotic space-hardened organic molecules called Polycyclic Aromatic Hydrocarbons. PAHs are normally unstable but may occur in places like the nebula in question, in nanostructured clusters that are extremely stable and radiation hardened.

[+] Cassini Probes the Hexagon On Saturn 280 comments
Riding with Robots sends us to a NASA page with photos of a little-understood hexagonal shape surrounding Saturn's north pole. "This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides," said Kevin Baines, member of Cassini's visual and infrared mapping spectrometer team. "We've never seen anything like this on any other planet." This structure was discovered by the Voyager probes over 20 years ago (here's an 18-year-old note on the mystery). The fact that it's still in place means it is stable and long-lived. Scientists have no idea what causes the hexagon. It's nearly big enough to fit four earths inside — comfortably larger than Jupiter's Great Red Spot. The article has an animation of clouds moving within the hexagon captured in infrared light.

      How is it confusing?

      The difference between Red Rectangle and Red Square is confusing because, if you read the article, they are different things. From the article:

      The researchers propose that similar conditions are contributing to the extreme symmetry of another system, the Red Rectangle, whose central star is cooler than that of the Red Square.

        And I don't see why it is worthless. imho it is completely relevant, on face value. No, I didn't RTFA. I was only saying that calling a square a rectangle isn't confusing if you look at it from a geometric perspective. The other replier cleared up the difference.

    I'm not a astrophysicist, but I've seen enough photographic artifacts to know you can get some interesting symmetrical single-color polygons through reflection and refraction that look remarkably like what is shown here. Is there any way to verify that this isn't a visual artifact, as opposed to an actual physical cloud? Or is the artifact itself a sign that there has to be a highly symmetrical set of objects creating it?

      There are some artifacts in the image. Notice the stars with 6 rays. The rays are created by support structures holding the secondary mirror of the telescope in front of the primary mirror. The fact that the square doesn't have hexagonal symmetry argues for its existence as a real object.

        But it highlighted star still does show the six-ray spikes the other starts do... the white light in the center just seems to have an hourglass shape that matches with the hexagonal spikes (also likely an artifact) that makes a square as it radiates out. Is it possible that the core of this star is collapsing into a quasar-like object, radiating in two opposite directions, each mostly perpendicular to our viewpoint? Those two narrowing radiating jets of light could match the hexagon thatches to make that white hourglass in the center, making the red square on the outside.

          First of all, I'd suggest looking at this higher resolution image [usyd.edu.au], available from this page [usyd.edu.au] with other fascinating graphics. I would agree that the more-or-less horizontal component of the central X (the sides of the hour glass) is in the same direction as the two "horizontal" components of the stars' hexagonal rays (by coincidence, I presume). However the vertical part of the central X does not point in the same direction as any of the hexagonal rays. This may be a simple demonstration of how an hourglass doesn' have hexagonal symmetry, but more importantly it suggests the hourglass isn't produced by the same process as the hexagonal spikes.


          Having said that, there are some faint hexagonal spikes created by the central object, but they are much fainter than the hour glass shape..


          I wouldn't use the term "quasar-like" because the word quasar is an acronym for "quasi-stellar radio source" and i don't think this object is the source of many radio waves

            Anonymous Coward is quite wrong. All the news articles about the Red Square are referring to it as a new nebula. It hasn't been "imaged thousands of times by hundreds of instruments over the past decade." It has only been imaged by two intruments over the last several years. It wasn't imageable until recent advance in adaptive optics, as AC should have known had AC read any of the articles. Mod parent uninformative.

    It is most devinitly NOT a lens artifact, look at the other stars, they have six points, those are definitly caused by the camera, the Keck telescope uses hexagonal mirrors in its array.

    Observant space enthusiasts will notice the excessively large number of hourglass morphologies that continue to appear in NASA's press releases. These hourglass morphologies can only be awkwardly called the result of gravitation. A cursory familiarity with laboratory plasma physics will help people to recognize that the most likely explanation is that these are in fact z-pinches wich result from Birkeland Currents. In a zoomed image, you can see the filamentary Birkeland Currents on two opposing sides of the red "square" being pinched down to a central point. These same filaments are also observable, but in cross-section, in the 1987A supernova remnant. Which components are visible varies from image to image, but the general morphology of the hourglass remains discernible.

    Here are some additional hourglass morphologies with pictures that have been observed:

    http://www.msnbc.msn.com/id/4953165/ [msn.com]
    http://www.thunderbolts.info/tpod/2005/arch05/0510 05eta-carinae.htm [thunderbolts.info]

    http://en.wikipedia.org/wiki/Image:Supernova-1987a .jpg [wikipedia.org]

    Since hourglass morphologies are somewhat disconfirming to traditional mainstream cosmologies (ie, the Big Bang), the fact that they continue to be observed all over the universe escapes the notice of professional astrophysicists, whose primary concern is to prove the Big Bang Theory and Stellar Evolution Theories. Objectively interpreting these shapes for what they most likely represent means dropping complicated, mainstream astrophysical explanations, and accepting the notion that electricity flows through space over plasma as we know it does within the laboratory. In these particular instances, at least, it is clear that the electrical force is dominant to gravity. We can opt to devise all sorts of gravitation-centric explanations for hourglass morphologies, but in doing so, we consciously opt to violate Occam's Razor.

    The implications of such strong evidence of electricity in space are overwhelming -- which provides all of the explanation necessary for avoiding abandonment of the traditional, more popular gravity-centric theories. When astrophysicists eventually accept that plasma in space has electrical resistance just like the plasma we observe in the laboratory, then they will begin to re-interpret all of our observations in terms of Maxwell's Equations rather than fluid and gas laws. And the enigmas of dark matter and dark energy will forever disappear, as this substitution can provide the exact forces necessary to explain things like how spiral galaxies can spin as if they are solid plates and how matter might repel other matter. The fact that we as a culture currently prefer to consider imaginary forces and particles to explain these "anomalies" rather than forces that we already understand will forever paint us to future generations as people who decided to favor the mathematicians and theories over our observational data and decades of experimental laboratory physics work.

    The evidence for electricity in space is not a sparse patchwork here and there. It is a flood of data that is only allowed to escape the notice of the public with the help of overconfident astrophysicists and a mob mentality within the space enthusiast community. Anybody who is intellectually curious about the universe and less concerned with what the people around them believe than what in fact appears to be true should consider learning more about plasma physics and the electric universe we live in.

        How you're able to determine charge density on the basis of temperature is somewhat of a mystery. We can't even do that for our own Sun. We know from the laboratory that plasma has three distinct modes of operation -- the dark mode, the normal glow mode and the arc mode -- and that it continues to conduct electricity within its dark mode even though plasma in this mode would emit neither photons nor infrared light/heat whatsoever. So, even if the process that creates the charged particles would emit infrared, the allegation is not that this process is occuring within this image. If it helps, you might consider that when you pass electricity through copper wires (which is also a form of plasma), your wires conduct quite well without glowing. Gaseous plasmas in fact conduct better than copper wires.

        The fact that you are not objectively considering the subject matter is evident in your decision to take a condescending tone. If you ever do decide to investigate the matter objectively, I think you will be surprised to find that there is indeed a serious debate here.
