Chromatic Aberration: Optical distortion in lenses where different colors of light focus at different points, blurring images.
Aperture: The diameter of a telescope's primary mirror or lens, dictating its light-gathering capability and resolution.
Electromagnetic Spectrum: The range of all types of electromagnetic radiation, from radio waves to gamma rays, each revealing different cosmic phenomena.
Adaptive Optics: Technology used in ground-based telescopes to correct for atmospheric distortions, producing sharper images.
