I have been unable to confirm either of these things.
Yes, sort of. But the Chandra image is of just a small portion at the centre of the Spitzer image.
Astronomical objects often have different appearances at different wavelengths.
In the case of the Orion Nebula Cluster, the Spitzer infrared observations trace warm dust which is distributed widely in this star-forming region.
On the other hand, the Chandra X-ray observations trace very hot gas, which is principally associated with the hot coronae of individual young stars.
In both cases, the data has been made into a coloured image, where red colours indicates the longer wavelengths and blue the shorter wavelengths in their respective ranges of wavelength sensitivity.
