The complex, cirrus-like emission from the Galactic center super bubble dominates this MeerKAT image. This is traversed by the Radio Arc, a complex of many parallel radio filaments. The radio bubble nestles against the diffuse Sagittarius A region in the lower center of the image. The bright dot near the center of this region is Sagittarius A*. Image credit: I. Heywood, SARAO.

The number of tree species and individuals per continent in the Global Forest Biodiversity Initiative (GFBI) database. This dataset (blue points in the central map) was used for the parametric estimation and merged with the TREECHANGE occurrence-based data (purple points in the central map) to provide the estimates in this study. Green areas represent the global tree cover. GFBI consists of abundance-based records of 38 million trees for 28,192 species. Depicted here are some of the most frequent species recorded in each continent. Some GFBI and TREECHANGE points may overlap in the map. Image credit: Gatti et al., doi: 10.1073/pnas.2115329119.

Mimas’ surface, like the surfaces of most of the other major Saturnian moons without atmospheres, is not pure ice but contains some dark impurities; the relatively dark markings appear along the lower portion of the walls of the 130-km-wide Herschel Crater (the peak in the middle of the crater is about as tall as Mount Everest; the impact that made it likely almost destroyed the moon) and some of the smaller craters; scientists interpret this darkening as evidence for the gradual concentration of impurities from evaporating icy materials in areas where the dark impurities slide slowly down the crater wall.
