The head of the sun is formed in the core meaning that it moves upwards. Because of this, the radiation zone is closer to the core meaning it's hotter than the convection zone.
A tool called a spectrometer allows astronomers to determine the chemical composition of planets and stars, as well as to indicate the speed and direction of a star or galaxy.
