Eta Corvi’s two-component debris disk was imaged by the Herschel Space Observatory at 70, 100, and 850 micrometers, as seen in the top row. The middle row shows synthetic images that were created based on best-fit models. Finally, the bottom row shows residual features that were left over after the synthetic images were subtracted from the real views, highlighting features that the models did not fully replicate.
