I report here on the analysis and interpretation of a Chandra observation of the supernova remnant Kes 32. Kes 32 is rather weak in X-rays because of a large interstellar absorption, which is found to be ∼4x10²²/m2, larger than previously reported. Spectral analysis indicates that the ionization age of this object is very young, with n_et∼4x10⁹/cm3 s and a temperature of kT_e∼1 keV. The X-ray emission peaks at a smaller radius than in the radio. The low ionization age suggests that Kes 32 is a young remnant. However, a young age is in contradiction to the relatively large apparent size, which indicates an age of several thousand years instead of a few hundred years. This problem is discussed in connection with Kes 32's unknown distance and its possible association with the Norma Galactic arm.
