Astronomy and references

Warrior Worlds is an independent series. These volumes contain astronomy and references; character stories and interpretations are reserved for the author.

Numerical values retain the NASA composite snapshot dated 25 September 2026. Linked studies document source-specific methods and uncertainties. Calculated values, limits and minimum masses are identified. The illustrations do not establish moons, local landscapes or life.

The edited jackets carry the Warrior Worlds identity and its own volume numbering. Jacket artwork is editorial imagery, excluded from planetary scene counts.

TOI-700 d · Light at the Terminator

The rain, ocean and basalt coast in this scene are a speculative realization near a possible day–night boundary. The warm horizon and reflected light illustrate stellar illumination; neither the sky color nor the weather has been measured here. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

Kepler-442 b · The Color of a Cooler Sun

The desert, arches and twilight palette are imagined. Placement in a potentially temperate irradiation range does not by itself establish liquid water, surface pressure, a rocky landscape or biological activity. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

Ross 128 b · A Planet in the Star’s Motion

The high plateau, mist and sunset are fictional local scenery. Their scale and colors are artistic choices; the stellar-motion measurements do not supply a map of this world. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

GJ 1214 b · The Reflective Veil

The pale cloud globe is an artistic translation of that atmospheric evidence. The orbital chamber, its viewing geometry and its contents are invented; the image does not imply a habitable exposed environment on the planet. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

Kepler-1661 b · An Orbit Around Two Suns

This scene places the viewpoint on an invented moon. No such moon is established by these sources. The nearby planetary disk, paired suns, shadows and rocky terrain form an illustrative arrangement, not a reconstructed view at a calculated observing date. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

WASP-17 b · Minerals in the Clouds

The scene therefore uses a fictional protected observatory. Its foreground mineral surfaces belong to that invented structure; the cloud globe’s visible colors and texture are an artistic rendering of an unresolved atmosphere. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

WASP-39 b · Chemistry Written by Starlight

The crescent, cloud bands and orbital chamber are illustrative. Their colors and spatial detail are not resolved by the transmission spectrum, and the habitat is a fictional place from which to view the planetary limb. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

WASP-76 b · Where Iron Can Condense

The illustration shows a fictional shielded viewpoint over the day–night boundary. The copper glow represents an artistic atmosphere, not molten ground. Neither the cloud pattern nor the safety of the imagined habitat follows from the observations. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

HR 8799 e · Light from a Young Giant

The icy foreground belongs to an invented moon. The giant’s ember coloring translates its thermal character into visible artwork and is not a calibrated human-eye view. The moon, ice and local sky brightness remain speculative. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.

PSR B1620-26 b · An Ancient World in a Star Cluster

The rocky foreground is an invented moon. The dense starfield evokes the cluster environment, but individual stellar positions and brightnesses are not a simulated sky. The pulsar does not appear as an enormous visible beacon. All depicted life is fictional. The visual connection to the cosmos is an artistic theme, not a claimed biological mechanism.
