The new study constrained the Enceladus’ global conductive heat flow by studying its seasonal temperature variations at its north pole (yellow). These results, when combined with existing ones of its

Kaiser Crater hosts a large field of sand dunes. Every winter the dunes are covered with a layer of seasonal carbon dioxide ice (dry ice). In early spring the ice

Upper: TESS TPF (Target Pixel Files) of Sector 17 for TOI-1472, and Sector 25 for TOI-1648. The color scale represents electron counts per pixel. Orange squares mark the pixels selected

Matrix plot summarizing the main differences between the 22 model scenarios. The x and y-axes show the scenario numbers. Values in the blue-shaded boxes show the absolute mean difference ()

D/H ratios for CH2DOH (left panel) and CH3OD (right panel) across the star-forming sequence. The spread per source type was calculated using all column densities listed in Table A. The

Chaperone-assisted protein remodeling enables microbial survival under extreme composting heat. During hyperthermophilic composting, microbial communities endure temperatures approaching 87 °C by activating a network of heat shock proteins that stabilize
