This gorgeous image was taken by the Herschel Space Observatory, using a photoconductor array camera and spectrometer, spectral and photometric imaging receiver and XMM-Newton (space satellite). What you are seeing here is the intensely cold nebula’s gas and dust emissions.
You can read a more in-depth, scientific explanation here on the NASA website. Herschel and XMM-Newton are both European Space Agency missions. The Jet Propulsion Laboratory in Pasadena, California contributed mission-enabling technology for two of Herschel’s science instruments.
