Unearthed: Massive Heat-Emitting Mass Found Beneath Moon's Surface
Astronomers have discovered a massive heat-emitting mass of granite rock buried beneath the surface of the Moon, beneath the Compton and Belkovich craters. This discovery is significant as granite is not commonly found outside of Earth. Using data from Chinese and American lunar orbiters, researchers have mapped temperatures below the surface and found that the suspected volcano, Compton-Belkovich, is emitting heat from a large source below it. The heat is believed to be caused by trapped radioactive material in the rock, and the volcano is thought to have last erupted 3.5 billion years ago.
