I will show results from Chandra ACIS-I observations of Kes 32 (G332.+0.1). A supernova remnant of 8arcmin size, that has never been imaged in X-rays before, largely as it was too obscured at low energies, and is situated in a complex region of the galaxy.
Chandra reveals that the X-ray morphology is similar to the radio morphology, although the shell seems to have a slightly smaller radius than indicated by the radio map. The X-ray spectrum, although of poor quality, does reveal strong Silicon, Sulfur, and Argon lines, proving that the emission is at least partially described by thermal emission. Both its morphology and spectrum therefore suggest that this object is an older version of a typical shell-type remnant like Cas~A.
