How do gamma rays help scientists figure out what other planets are made of?

Gamma rays help scientists analyze the composition of other planets by detecting the gamma radiation emitted from their surfaces and atmospheres. Instruments aboard spacecraft can measure these gamma rays, which are produced when cosmic rays interact with the elements in a planet's surface. By identifying the specific gamma-ray signatures associated with different elements, scientists can infer the mineral and elemental composition of the planet. This information enhances our understanding of planetary geology and evolution.
