The Mark Shared by Titan and Pluto
Two distant worlds show an infrared absorption near the same wavelength, but the artwork joins them in a way the data do not.

THE OBSERVATION
What we can actually see.
Webb spectra show an absorption centered near 5.113 micrometers on Titan. A feature near the same wavelength appears on Pluto, though the Pluto band is much broader. The Titan result was seen with two Webb instruments after the researchers modeled the effects of Titan’s atmosphere and haze. The absorber remains unidentified, and matching centers do not establish that both worlds contain the same material.
THE ILLUSTRATION
What the artwork imagines.
The composition treats the two worlds as if they share a visible signal. There is no beam or communication between them; a spectral dip is a reduction in reflected light at particular wavelengths. The arrangement, colors, and apparent connection are artistic devices for a question about chemistry.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
This image opens an illustrated investigation of why a similar spectral mark on two cold worlds is intriguing, and why the different band shapes matter more than an easy claim of a common substance.
