Final answer:
Using different types of electromagnetic waves allows scientists to gain a more comprehensive understanding of celestial bodies, as each type reveals distinct features, much like how you'd get a fuller understanding of a person than just by their shoes.
Step-by-step explanation:
Using different types of electromagnetic waves provides a more complete understanding of celestial bodies since each wavelength can reveal different characteristics of these objects. For instance, radio waves can show cold gas clouds which might form stars, visible light can show where stars are currently formed, and X-rays can point to the presence of extremely hot gas around black holes. The electromagnetic spectrum extends far beyond what our eyes can see, and each type of radiation—from radio waves to gamma rays—carries its own unique set of information. Just as you can't understand a person by only looking at their shoes, astronomers can't understand stars and galaxies by only observing the visible light. By respecting and utilizing the full electromagnetic spectrum, astronomers can decode the spectras of stars and galaxies, learning about their chemical makeups and how they evolve over time.
