Like night vision goggles, telescopes based on infrared  can also "see" in the dark.
-
THis helps scientist peer into otherwise obscured "dark" regions to see observe young stars and stars being born.

>Infrared radiation from warm dust generates much of the glow seen here from the Perseus Molecular Cloud. Clusters of stars, such as the bright spot near the left side of the image, generate even more infrared light and illuminate the surrounding clouds like the Sun lighting up a cloudy sky at sunset. Much of the dust seen here emits little to no visible light (in fact, the dust blocks visible light) and is therefore revealed most clearly with infrared observatories like Spitzer.
