A cutaway depicts the interior of Neptune (left). In the new experiment, Kraus et al studied a plastic simulating compounds formed from methane -- a molecule with just one carbon bound to four hydrogen atoms that causes the distinct blue cast of Neptune; methane forms hydrocarbon (hydrogen and carbon) chains that respond to high pressure and temperature to form ‘diamond rain’ in the interiors of ice giants like Neptune; the authors were able to recreate similar conditions using high-powered optical lasers and watch the small diamonds form in real time with X-rays.

This is a false color image of Saturn, with exaggerated colors to enhance subtle variations in color to bring out details of the cloud structure. The view is centered on 46 degrees north latitude on Saturn. The filter centered at 727 nm was used for red in this image; the filter centered at 750 nm was used for blue.

The atmospheric superrotation at the upper clouds of Venus. While the superrotation is present in both day and night sides of Venus, it seems more uniform in the day (AKATSUKI-UVI image, right), while in the night this seems to become more irregular and unpredictable (composite of Venus Express/VIRTIS images, left).

This image shows Watson 021, a single H7 ordinary chondrite, weighing 135 g. The sample has a large crack, lined with alteration minerals, that runs down its middle and only one third of its fusion crust remains intact. This meteorite shows near complete oxidation of its reduced metal and sulfide phases making this a W4 chondrite. Watson 021 is extensively shocked, exhibiting globular silicate metal emulsions and shock veins that crosscut the sample. Tait et al found that microbial communities in samples of Nullarbor Plain soil are more diverse than those in Watson 021 and other meteorites, which are highly uniform in their species evenness and species richness.
