We use a deep XMM-Newton Reflection Grating Spectrometer observation to examine the X-ray emission from the core of the Centaurus cluster of galaxies. We clearly detect Fe XVII emission at four separate wavelengths, indicating the presence of cool X-ray emitting gas in the core of the cluster. Fe ions from Fe XVII to xxiv are observed. The ratio of the Fe xvii 17.1 A lines to 15.0 A line and limits on O VII emission indicate a lowest detected temperature in the emitting region of 0.3 to 0.45…
