Yolk in the intestinal lumen of Caenorhabditis elegans larva after being left on a plate with no food apart from vented yolk for 4 h. Top: Nomarski microscopy image. Bottom left: larva imaged immediately after removal from plates using reflectance confocal microscopy (RCM) to highlight the refractive material of the terminal web that surrounds the intestinal lumen (red) and superimposed airyscan image (green) for GFP-labeled yolk. Bottom right: same larva imaged 100 min later showing yolk no longer in the lumen, either due to defecation or digestion; this disappearance confirms that the green fluorescence indicated in the central panel corresponds to yolk within the intestinal lumen. Scale bar - 20 μm. Image credit: Kern et al., doi: 10.1038/s41467-021-25821-y.

Pluto’s haze layer shows its blue color in this picture taken by the New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC). The high-altitude haze is thought to be similar in nature to that seen at Saturn’s moon Titan. The source of both hazes likely involves sunlight-initiated chemical reactions of nitrogen and methane, leading to relatively small, soot-like particles -- called tholins -- that grow as they settle toward the surface. This image was generated by software that combines information from blue, red and near-infrared images to replicate the color a human eye would perceive as closely as possible.
