Phys.org's The detection of phosphine in Venus' clouds is a big deal, and here's how we can find out if it really is life contains part of a NASA/JPL-Caltech image which is on the cover of Aerial Platforms for the Scientific Exploration of Venus, JPL D-102569
What caught my eye is the inclusion of what I assume is chromatic aberration in the rendering of what a future balloon payload in Venus's atmosphere would look like if you happened to be next to it and snapping a photo.
What I can't figure out is the ordering of the colors. The first image of the hanging payload is cropped from the bottom of the image, and the second, of the top of the balloon, is at the top. The payload shows both blue and red edges on the tops of surfaces, the balloon top only red.
I've added an annotated image indicating color of horizontal edges at the bottom of the screen; some top edges are blue, some are red, likewise bottom edges.
Do all of these color gradients in the rendering show the expected behavior for simple chromatic aberration of a single lens material, where blue light is refracted more strongly?
Being NASA-meticulous, it's possible they used a single material like sapphire or diamond for the lens in this simulation to minimize interaction with chemicals in Venus' atmosphere.
A concept for an aerial platform at Venus. Two connected balloons could take turns to inflate, allowing the balloon to control the altitude at which it floats. An instrument package would then hang from below the balloons. Credit: NASA/JPL-Caltech
