Abstract:Granites are nearly absent in the Solar System outside of Earth. Achieving granitic compositions in magmatic systems requires multi-stage melting and fractionation， which also increases the concentration of radiogenic elements. Abundant water and plate tectonics facilitate these processes on Earth， aiding in remelting. Although these drivers are absent on the Moon， small granite samples have been found， but details of their origin and the scale of systems they represent are unknown. Here we report microwave-wavelength measurements of an anomalously hot geothermal source that is best explained by the presence of an approximately 50-kilometre-diameter granitic system below the thorium-rich farside feature known as Compton–Belkovich. Passive microwave radiometry is sensitive to the integrated thermal gradient to several wavelengths depth. The 3–37-gigahertz antenna temperatures of the Chang’e-1 and Chang’e-2 microwave instruments allow us to measure a peak heat flux of about 180 milliwatts per square metre， which is about 20 times higher than that of the average lunar highlands3，4. The surprising magnitude and geographic extent of this feature imply an Earth-like， evolved granitic system larger than believed possible on the Moon， especially outside of the Procellarum region5. Furthermore， these methods are generalizable: similar uses of passive radiometric data could vastly expand our knowledge of geothermal processes on the Moon and other planetary bodies.

China's AI approach offers the Global South partnership over dependency
Lead: By treating AI as a public good rather than a proprietary product， China is establishing itself as the technology partner of choice for Global South nations， offering an alternative to Silicon Valley's profit-driven model that locks countries into dependency.

Sites on the Antarctic plateau are characterized by comparatively weak turbulence in the free atmosphere above a strong but thin boundary layer. Here we report measurements of night-time seeing at Dome A， using a differential image motion monitor. Located at a height of just 8 metres， it recorded seeing as low as 0.13 arcseconds， and provided seeing statistics that are comparable to those at a height of 20 metres at Dome C. This indicates that the boundary layer was below 8 metres for 31 per cent of the time， with median seeing of 0.31 arcseconds， consistent with free-atmosphere seeing. The seeing and boundary-layer thickness are found to be strongly correlated with the near-surface temperature gradient. The correlation confirms a median thickness of approximately 14 metres for the boundary layer at Dome A， as found from a sonic radar. The thinner boundary layer makes it less challenging to locate a telescope above it， thereby giving greater access to the free atmosphere.
