What instruments help scientists see things they could not normally see?

Scientists use various instruments to observe phenomena beyond normal human perception. Microscopes, for instance, allow the examination of tiny structures like cells and bacteria, while telescopes enable the observation of distant celestial bodies. Additionally, tools like spectrometers analyze light to reveal the composition of materials, and particle accelerators help visualize subatomic particles that are otherwise invisible. These instruments expand our understanding of the natural world by revealing details that would remain hidden to the naked eye.
