Plasma spirals

Stars and binary star systems creating spirals in space? Are these plasma filaments and the mysterious glow is energised plasma?

What created the strange spiral structure on the upper left? No one is sure, although it is likely related to a star in a binary star system entering the planetary nebula phase, when its outer atmosphere is ejected. The huge spiral spans about a third of a light year across and, winding four or five complete turns, has a regularity that is without precedent. Given the expansion rate of the spiral gas, a new layer must appear about every 800 years, a close match to the time it takes for the two stars to orbit each other. The star system that created it is most commonly known as LL Pegasi, but also AFGL 3068. The unusual structure itself has been cataloged as IRAS 23166+1655. The featured image was taken in near-infrared light by the Hubble Space Telescope. Why the spiral glows is itself a mystery, with a leading hypothesis being illumination by light reflected from nearby stars.

A surprising and strange spiral structure surrounding the old star R Sculptoris… The team using ALMA, the most powerful millimeter/submillimeter telescope in the world, mapped the spiral structure in three-dimensions. The astronomers say this is the first time a spiral of material, with a surrounding shell, has been observed.

“We’ve seen shells around this kind of star before, but this is the first time we’ve ever seen a spiral of material coming out from a star, together with a surrounding shell.”

Do the spirals appear to not actually be smooth curving lines but made of angles? Similar to lots of craters that seem to be hexagonal craters?

Many petroglyphs and megalithic rock carvings such as those found in Malta show spirals and sun (stars) like objects with spirals attached. Plasma mythology?

Norway plasma spiral

There was a mysterious spiral in the skies of Norway in December 2009.

What was the Norway spiral? Birkeland Current: Again, not likely. A Birkeland Current a magnetic field aligned current in the Earth’s magnetosphere which flows from the magnetotail towards the Earth on the dawn side and in the other direction on the dusk side of the magnetosphere. Birkeland currents often show filamentary, or twisted “rope-like” magnetic structure, and they create the aurora Borealis and Australis when they reach the upper atmosphere.

Detecting space plasma spirals

Scientists, using the NASA/ESA Hubble Space Telescope found a similar spiral, but without a surrounding shell, while observing the star LL Pegasi. Unlike the new ALMA observations, however, the astronomers could not create a three-dimensional map of the structure. Hubble observations saw the dust while ALMA detected the molecular emission.

ALMA detects the warm glow of carbon monoxide molecules in the far infrared through the multimeter wavelengths allowing astronomers to map the gas emissions surrounding the star in high-resolution. The team believes the strangely shaped bubble of material was probably created by an invisible companion star orbiting the red giant.
