Cross-section of the exoplanet Kepler-138d; like the Earth, this exoplanet has an interior composed of metals and rocks (brown portion), but Kepler-138d also has a thick layer of high-pressure water in various forms: supercritical and potentially liquid water deep inside the planet and an extended water vapor envelope (shades of blue) above it; these water layers make up more than 50% of its volume, or a depth of about 2,000 km.

Perseverance’s Navigation Camera (Navcam) observations of the direct dust devil encounter: the Navcam scene (the average background image, top panel) and each dust devil image processed to dust amount (five lower panels), masking out only the truly indeterminate areas (gray); the color scale ranges from optical depth, τ = 0 at the bottom (blue) to τ = 0.12 at the top (yellow), and is linear in between; the areas with low signal-to-noise ratio are masked out, and the images also show non-random noise (banding from instrument electronics during readout); the grid on the scene image (top panel) is 5 degrees in local level azimuth and elevation; the darker gray contours are elevation=0 degrees and azimuth=165 degrees.
