I will report on the work done by our team on the study of early type galaxies in both clusters and the field using Spitzer, GALEX and optical observations.

I will mainly concentrate on the new view that Spitzer data is offering us on early type galaxies. Indeed the MIR window is particularly interesting for the presence of the emission from the silicate-rich dust in circumstellar envelopes of AGB stars and of a pletora of features emitted by the ISM. Spitzer observations allows us to both study the stellar populations from a new prospective and to characterize the physical processes active in early-type galaxies nuclei.
