Infrared Stellar Baby Pictures
Infrared radiation from the Sun warms Earth and makes life possible here. This light comes in three wavelength ranges: near, mid, and far infrared. Our atmosphere absorbs infrared, and we cannot detect much of it from the ground. Instead, we use spacecraft to observe it.
Stellar nurseries are active places, but the clouds of gas and dust that give birth to stars keep us from seeing the action. Infrared light from newly formed objects, however, passes through those clouds.
The Spitzer Space Telescope focused its infrared-sensitive cameras on NGC1333 (left) in the constellation Perseus. Jets from newborn sunlike stars are sculpting their birth nebula.
This is what people look like if we could see them in infrared.
