We present new mid/far infrared images of the two dwarf/compact elliptical galaxies that are satellites of M31, NGC 185 and NGC 147, obtained with the Spitzer Space Telescope. Spitzer's high sensitivity and spatial resolution enable us for the first time to look directly into the detailed structure and properties of the dust clouds properties and content of these systems. The images of NGC 185 at 8 and 24 micron display a complex and fragmented infrared emission coming from both very small dust particles and larger grains. The extended dust emission is spatially concentrated in two large main emission regions, seen at all wavelengths from 8 to 160 micron. On the other hand, the dwarf galaxy NGC 147, which lies at roughly the same same distance from M31 as NGC 185, shows no diffuse infrared emission in the same wavelength range. In the case of NGC 185, we also present spectroscopic observations with IRS of the main emission regions.
