Infrared light has a large range of applications, and is often utilized where visible light cannot be detected, or something is blocking visible light but does not block infrared light. For example, when looking toward the center of the Milky Way large amounts of dust obscure the visible light that emanates from the center of the galaxy. This dust though does not obscure infrared light at certain wavelengths, and so astronomers can use cameras that are sensitive to this infrared light to obtain a picture of this region of space. Infrared light is also used in thermal imaging systems, and night-vision instruments are often sensitive to the infrared wavelengths that are emitted by warm objects.

they did it to get more detailed pictures of space

Infrared is heat. When you feel the warmth of a space heater, you feel the effect of infrared radiation. The other uses are motion detection (infrared sensor) and night-vision (live animals have a heat signature, a blurred image, against a colder background at night). ======================

The Infrared Astronomical Satellite was the first-ever space-based observatory to perform a survey of the entire sky at infrared wavelengths. It uses infrared light.
