Recently, using data from the Chinese lunar probes Chang’e-1 and Chang’e-2, scientists found excessive heat below the surface of a suspected volcanic feature on the Moon known as Compton-Belkovich. The existence of such a large hotspot on the lunar surface can only be explained if the underlying granite rock contains elements undergoing radioactive decay, such as thorium and uranium.
