The floating engine gardens
An atmosphere filled with factories. A harvest of engines instead of fruit.
The imagined scene
The host system is real. All alien organisms, robots, societies and social histories are fictional. Moons, rings, terrain and weather are artistic assumptions unless specifically supported by a cited source. These images are not calibrated simulations of the sky.
The scientific anchor
TOI-1338 b is a confirmed circumbinary planet in the NASA catalog: it orbits two stars in about 95.4001 days and has radius 7.661 Earth radii. The planet is gas-rich. The viewpoint is an invented atmospheric habitat, not a habitable planetary surface. No depicted moon, artificial intelligence, civilization or disappearance of organic life is an observed discovery.

NASA composite catalog values may combine different papers. Errors and upper/lower limits are retained. “Calculated Value” means derived or estimated. Msini is a minimum mass. Missing values are unknown. A multiple-star system’s single stellar row does not describe every component. Equilibrium temperature is not a measured surface temperature.

What about life?
Likely a deep gaseous envelope, without a solid exterior surface. Atmospheric or moon life is speculative; this is not proof that all life is impossible. No confirmed life; no planet-specific biosignature literature review in this release.
