The picture of the milky way galaxy was taken over a year ago in infrared light. The infrared light waves range from red light to violet. Astronomers took this image to learn more about how stars are formed. Thick clouds of dust and gas congeal and form stars. It says that some stars are so dark they're even dark when they are viewed in infrared light. There are even traces of supernovas which are puff balls which used to be stars.
