Detailed explanation-1: -All electromagnetic radiation is light, but we can only see a small portion of this radiation-the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum.
Detailed explanation-2: -Even visible light is distorted by the atmosphere, so clearer pictures can be got from orbiting telescopes. For example, the Hubble Space Telescope is positioned outside the Earth’s atmosphere and takes very sharp images of very distant objects in space.
Detailed explanation-3: -Why is it useful to examine the universe using parts of the electromagnetic spectrum other than visible light? Objects in the universe emit many forms of electromagnetic radiation besides visible light. When we detect these other forms of radiation we can view celestial objects and events in greater detail.
