Tyson describes how different types of telescopes are used to observe various parts of the spectrum, revealing information about celestial objects that are otherwise invisible to the naked eye. By studying the electromagnetic spectrum, scientists can gather data on the composition, temperature, and movement of distant stars and galaxies.
