LHS 1140 b — night
Hypothetical water-rich world with a localized open-water region amid ice; neither ocean nor life is confirmed. Six-finned filter feeders, nacreous shell rafts, living black microbial ridges.
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
This illustration is associated with LHS 1140 b, a catalogued exoplanet orbiting LHS 1140. The available catalog measurements below describe the real system; they do not establish the illustrated scenery.

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?
Passes a deliberately broad 0.25–1.75 Earth-flux triage window. This is not a calculated habitable zone or evidence of water or life. Atmosphere, surface pressure, water inventory, stellar activity and orbital history remain unassessed. No confirmed life; no planet-specific biosignature literature review in this release.
