Bipolar Nebula Polar Axis

You are suspended inside the polar lobe of a dying star's final exhalation — a cathedral of ionized oxygen arching hundreds of cubic light-years above and below in perfect bilateral symmetry, its walls built not of stone but of stacked forbidden-line emission shells, each concentric skin radiating a fractionally deeper shade of electric teal than the last, from palest aquamarine at the outer rim to an intense cobalt-turquoise near the central axis. The lobes are pinched at the equator by a dense molecular torus of reddish umber and compressed ash, its inner edge peeling apart under the hard ultraviolet assault of an Earth-sized white dwarf burning at 150,000 kelvin — a sourceless kernel of blue-white brilliance that casts no ordinary shadow, only an omni-directional aquamarine ambient that makes the interior feel simultaneously enclosed and boundlessly open. At this scale, the gas you float within is functionally a perfect vacuum — particle densities thousands of billions of times thinner than the air of any world — yet integrated across light-years of depth it resolves into luminous membranes, translucent forbidden-line curtains, and corrugated shell walls ridged where a fast stellar wind overtook slower ejecta ejected millennia before, the entire structure a frozen record of a star's last ten thousand years of self-erasure. Through the open mouth of the far lobe, ancient field stars burn as cold white pinpoints behind teal gauze, their light measurably reddened by the gas column between them and you, calibrating by their very dimness the inconceivable depth of glowing material that now constitutes everything you can see.
