Observing with Light Waves
Explain how the electromagnetic spectrum is the primary tool of modern astronomy — different wavelengths (radio, infrared, visible, ultraviolet, X-ray, gamma-ray) reveal different phenomena, why some telescopes must be in space, and what specific discoveries each wavelength range has enabled (e.g. CMB in microwave, black hole jets in X-ray, cold gas clouds in radio)

If your child was told that we can't see most of the universe with our eyes, could they explain why — and describe two types of telescope that detect something other than visible light, naming what they've helped us discover?

Check understanding
- Lists at least four regions of the EM spectrum and gives a specific astronomical object or phenomenon observed in each
- Explains why some telescopes must be placed in space (Earth's atmosphere blocks X-ray, gamma-ray, and much infrared radiation)
- Describes the James Webb Space Telescope or Hubble and explains which part of the spectrum each primarily observes and why that was chosen
