Electricity in Space ! Part II
#3 The Central Object Series : Dusty vs. Clear
Dusty : NGC 6302, Calabash, CRL 618, eta Carinae
Clear : NGC 7293 Helix, NGC 6369, NGC 3132, NGC 2818, M57
Here we compare Central Stellar Objects : those which are highly dust obscured, with ones that are surrounded by a very large, open, clear space.
Why the difference, Dusty vs Clear ? Age ? Development ? We're not sure yet. Thus their value for study !

Those Dust Obscured :
NGC 6302
The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects. This nebula's 'wingspan' covers over 3 light-years ! NGC 6302 the Butterfly Nebula or Bug Nebula, has an estimated Central Object surface temperature of over 200,000 degrees C. This SGZ nebula has become exceptionally hot, shining brightly in ultraviolet light, but hidden from direct view by a dense torus of dust.cutting across the bright central object cavity near the center of view, which is almost edge-on to our line-of-sight. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). This sharp close-up was recorded by the Hubble Space Telescope in 2009, and the image data was later reprocessed to better show the remarkable details of the surrounding astrophysical plasma 'wings', highlighting in particular; light emitted by oxygen (shown as blue), hydrogen (green), and nitrogen (red).

The Calabash Nebula or Rotten Egg Nebula
This once-normal star now finds itself in an SGZ situation, where the Z-Pinch force is causing the central region to contract into a white dwarf. Some of the liberated star energy causes the outer plasma envelope to expand. In this case the result is a photogenic display as the million-kilometer per hour material rams into the surrounding interstellar medium, a supersonic shock front forms where ionized hydrogen and nitrogen glow blue. The complex shock front had been hypothesized previously but never so clearly imaged. Thick gas and dust hide the energetic central star object.
The Rotten Egg Nebula, also known as the Calabash Nebula and OH231.8+4.2, is about 1.4 light-years in width, and located about 5,000 light-years away toward the constellation of Puppis.

CRL 618
Only a few hundred years ago CRL 618 appeared as a relatively modest red giant star. Since then it has started evolving quickly, expelling hot materials in complex jets and rings, jets moving outwards at an estimated faster than 700,000 kilometers per hour, to reveal a remaining hot white-dwarf star. Much remains unknown about planetary nebulae formation, including details of how geometries like this form. Yes, Mainstream Astrophysics remains very much 'in the dark' about SGZs. Radio Astronomy believes CRL 618 has an extraordinary abundance of carbon-chain molecules, making it a possible great 'gas station in space' for future travelers 'to stop and fill their tank' !!

Eta Carinae
The star eta Carinae may be about to explode. But no one knows when - it may be next year, it may be in a million years. Star eta Carinae's mass is huge - about 100 times greater than our Sun - making it an excellent candidate for a full blown supernova. Historic records show about 170 years ago eta Carinae underwent an unusual outburst that made it the second brightest star in the southern sky. This outburst appears to have created the Homunculus Nebula. Then 20 years later, after ejecting more mass than our Sun, eta Carina unexpectedly faded. Jets now bisect the lobes emanating from the central star region. Surrounding these lobes are red-tinted debris captured only by its glow in a narrow band of red light. This debris is expanding most quickly of all, and includes streaming whiskers and bow shocks caused by collisions with previously existing material. Star eta Carina still undergoes unexpected outbursts, and while located in the Keyhole Nebula, it is the only star currently thought to emit natural LASER light. This image, taken in 1996, brought out new details in the unusual nebula that surrounds this rogue star. Now clearly visible are; a hot central region, two distinct lobes, and strange radial streaks. The lobes are filled with lanes of plasma gas and dust which absorb the blue and ultraviolet light emitted by the central object. The streaks remain unexplained.

Those with a Clear Central Region :
NGC 7293 The Helix Nebula
The Helix Nebula is estimated to be 450 light-years from the Sun, in the direction of the constellation Aquarius. At that distance it may well be our closest planetary nebula. In this color image the nebula glows red in the light of nitrogen and hydrogen atoms, the oxygen atoms are in blue-green hues, as energized by the ultraviolet radiation from the central star. The main rings themselves, though faint, have an angular size about half the full Moon, and span about 3 light-years in total width at that distance. Because it is so close, it is a prime subject for study by astronomers. When the Hubble Space Telescope was focused near the inner edge of the main ring, at about the 12 o'clock position in the above image, it resolved some of the spoke like radial structures into intriguing 'cometary knots', prompting much thought on how and why these structures formed. The even fainter outer halo features give the nebula a span of well over six light-years. The white dot at the Helix's center is this Planetary Nebula's hot, central star. A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.

NGC 6369 The Little Ghost Nebula
This pretty planetary nebula, cataloged as NGC 6369, was discovered by 18th century astronomer William Herschel as he used a telescope to explore the medicinal constellation Ophiucus. Round and planet-shaped, the nebula is also relatively faint and has acquired the popular moniker of Little Ghost Nebula. Planetary nebulae are in general not at all related to planets, they were named this because in early telescopes they appeared round and fuzzy, and were thought to someday 'condense' into a planet, but instead are destined to have plasma expand into space while the original star's core shrinks to become a white dwarf star.
The transformed white dwarf star, seen near the center, radiates strongly at ultraviolet wavelengths and powers the expanding nebula's glow. Surprisingly complex details and structures of NGC 6369 are revealed in this delightful color image composed from Hubble Space Telescope data. The nebula's main ring structure is about a light-year across and the glow from ionized oxygen, hydrogen, and nitrogen atoms are colored blue, green, and red respectively. Over 2,000 light-years away, the Little Ghost Nebula offers a glimpse into the fate of stars that become entraped in a Z-Pinch, and find that stellar material then expelled and reorganized by the Field forces created by the Electric Energy flows, creates an unexpected display of Beauty !

NGC 3132 The Eight Burst Nebula or Southern Ring Nebula
It's the dim star near the center of NGC 3132 that is the central stellar object, the much brighter star is totally closer to us and not at all close to 3132. Nicknamed the Eight-Burst Nebula and the Southern Ring Nebula, about 2,500 light-years from Earth, the glowing plasmas in this false-color picture are energized by the hot surface radiations of the energetic central star. Although photographed to explore unusual symmetries, it's the asymmetries that help make this planetary nebula so intriguing. Neither the unusual non-circular shape of the surrounding cooler shell, nor the structure and placements of the cool filamentary dust lanes running across the nearly half a light-year in diameter 3132 are well understood. Yes, Mainstream has great difficulties making sense of things when they continue to adamantly refuse to acknowledge that Electricity plays a vital and central role in their formation and subsequent Field-organized structures.
There is variation in false color protocols, here: Oxygen- blue-green, nitrogen- yellow, hydrogen- red.

NGC 2818 The Birds Nest Nebula
NGC 2818 is a beautiful planetary nebula that seems to lie within an open star cluster, NGC 2818A, that is some 10,000 light-years distant toward the southern constellation Pyxis (the Compass). At the distance 2818 would be about 4 light-years across. But accurate velocity measurements (using Redshift data) show that the nebula's own (redshift) velocity is very different from the cluster's member stars (redshift). The result is strong evidence that NGC 2818 is only by chance found along the line of sight to the star cluster and so may not share the cluster's distance or age (and thus width size). The Hubble image is a composite of exposures through narrow-band filters, presenting emission from nitrogen, hydrogen, and oxygen atoms in the nebula as red, green, and blue hues, respectively.

M57 or NGC 6720 The Ring Nebula
The Ring Nebula (M57), is more complicated than it appears. The easily visible central ring is about one light-year across, but this remarkable combined exposure by the James Webb Space Telescope and the Hubble Space Telescope explores this popular nebula with deep exposures in visible and infrared light. Strings of gas, like eyelashes around a cosmic eye, become evident around the Ring in this digitally enhanced featured image in assigned colors.
These long filaments may be caused by the 'shadowing' of knots of dense gas in the ring from the energetic light emitted by the central region star. The Ring Nebula is an elongated planetary nebula, a type of nebula that results from our viewing it "down the pipe" in the sense that it is 'rotated' 90 degrees to us from a 'side view'. We now know that its iconic shape is due to our lucky perspective, as we are looking down the long central axis of these 'round like' nebulae, thus the appearance as we see the 'cones' from an 'end view' ! M2-9 would look like M57 if rotated 90 degrees to an 'end view' !
The central oval in the Ring Nebula lies about 2,500 light-years away toward the musical constellation Lyra.
