Can someone clarify if the colours visible in the image are an artifact of instrument used for capturing the image? Or are they natural colours of stars?

- lotharbot 16y agoJudging from the name of the image, it was taken by Spitzer, which is an Infrared telescope [1]. The colors you see in this image do not represent visible light. [1] http://www.spitzer.caltech.edu/ http://www.spitzer.caltech.edu/

- turnersauce 16y agoThis is most likely a multi-wavelength image, where the various wavelengths were coloured differently in the composite. Some more detail about what the colours can tell us is given here: http://apod.nasa.gov/apod/ap080605.html http://apod.nasa.gov/apod/ap080605.html
