When astrophysicists measure light from a distant star, they can break up the starlight into its component colors, creating a spectrum from long wavelength red to short wavelength blue, by beaming the light through a mechanical prism. Similarly, when geophysicists measure a planet's magnetic field, they can break up the field into long and short wavelength components by running the data through a kind of digital prism called "spherical harmonic analysis." And much as astrophysicists can say… CONTINUE READING
