Vasas et al. show 3 male orange sulphurs (Colias eurytheme). These butterflies display strong angle-dependent UV iridescence on the dorsal side of their wings. The UV-iridescent portions appear more orange to the human observer than the otherwise yellow wings (see human-visible inset). The avian false color depiction (main image) is based on the coordinates of the receptor noise-limited (RNL) opponent space. Coordinates in this space represent differences in an animal’s photoreceptor responses, and the distances between the coordinates approximate the perceptual distances between the colors. The inset color key illustrates human-visible colors around the perimeter of a circle colored according to RNL coordinates, where UV colors start at the epicenter and mix with other colors. In this depiction, the UV-iridescent portions appear purple, because they most strongly reflect in the ultraviolet and the red part of the spectrum. The ventral part of the wings, visible when the animals are in their resting position, are depicted as gray-brown, just like the leaves, as they are close to the achromatic point.

This Hubble image shows various distant galaxies in the constellation of Cetus: most of the galaxies are very small, but there are a few larger galaxies and some stars where detail can be made out; in the center there is an elliptical galaxy with a brightly glowing core and a broad disk; a reddish, warped ring of light, thicker at one side, surrounds its core; a small galaxy intersects the ring as a bright dot.

This Webb image of Jupiter shows stunning details of the majestic planet in infrared light. In this image, brightness indicates high altitude. The numerous bright white ‘spots’ and ‘streaks’ are likely very high-altitude cloud tops of condensed convective storms. Aurorae, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet. By contrast, dark ribbons north of the equatorial region have little cloud cover.
