Final answer:
Electromagnetic energy helps explore space via the Cosmic Microwave Background for studying the Big Bang, specialized telescopes by Arthur B. C. Walker for solar observations, and radio telescopes like Arecibo for detecting radio waves from astronomical phenomena.
Step-by-step explanation:
Electromagnetic energy is crucial in astronomy for studying the universe and has been used in several innovative ways to enhance our knowledge of space. Here are three examples:
- Observations of the Cosmic Microwave Background (CMB): Physicists Arno Penzias and Robert Wilson detected faint microwave radiation, which provided evidence for the Big Bang theory and helped us to understand the conditions of the early universe.
- X-ray and Ultraviolet Astronomy: Arthur B. C. Walker developed specialized telescopes and instruments for observing the Sun's atmosphere and corona in X-ray and ultraviolet light, significantly advancing our understanding of the Sun's processes and the nature of stars.
- Radio Telescopes: Facilities like the Arecibo Radio Telescope and Parkes Observatory use large dish antennae to detect radio waves from space, enabling the study of distant galaxies, pulsars, and other astronomical phenomena.
These methods allow astronomers to receive and interpret different wavelengths of electromagnetic radiation, each providing unique information about astronomical objects and phenomena.
