Pluto’s Broader Mark
Pluto shows absorption near Titan’s wavelength, but its wider band resists a simple shared-material story.

THE OBSERVATION
What we can actually see.
The published Webb comparison finds a Pluto absorption near the same central wavelength as Titan’s feature. Pluto’s band is much broader. A matching center alone cannot identify a compound; band shape, mixtures, grain properties, and temperature also matter.
THE ILLUSTRATION
What the artwork imagines.
The icy plains and dark terrain are an artist’s setting for a spectral puzzle. The composition is neither a New Horizons photograph nor a map of where the unknown absorber lies. No instrument has identified the pictured surface patch as its source.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article sets two remote worlds side by side to ask whether a shared spectral neighborhood reflects the same chemistry or two different physical stories.
