In astronomy, the type of light often used to study distant galaxies and stars is infrared light. Here are the steps explaining why:

1. Infrared light has a longer wavelength than visible light. This allows it to penetrate through dust clouds in space that would otherwise obscure our view of distant celestial bodies when using visible light.

2. Many objects in space, such as stars and galaxies, emit infrared light. By studying this light, astronomers can learn more about these objects' composition, temperature, and distance.

3. Infrared light can also help astronomers see objects in space that aren't hot enough to emit visible light. This includes planets, asteroids, and other cold bodies.

4. Finally, the universe is expanding, and as a result, light from distant galaxies is redshifted. This means that the light is stretched out, moving it from the visible spectrum into the infrared spectrum. By using infrared light, astronomers can study these very distant galaxies.
