                                               This image from the Chandra X-ray
                                               Observatory illustrates the two-dimensional
                                               spectral capability of the Advanced CCD
                                               Imaging Spectrometer (ACIS) instrument. The
                                               image shows the supernova remnant Cas A,
                                               where the colors reflect the temperature of
                                               the hot gas. Red colors correspond to
                                               temperatures below approximately 20 million
                                               degrees kelvin, and blue colors correspond
                                               to temperatures above approximately 30
                                               million degrees kelvin. Image courtesy
