We present the Chandra discovery of soft diffuse X-ray emission in NGC 4151 (L[0.5-2keV]~10^{39} erg s\(^{-1}\)), extending ~2 kpc from the active nucleus and filling in the cavity of the HI material. The best fit to the X-ray spectrum requires either a kT~0.25 keV thermal plasma or a photoionized component. In the thermal scenario, hot gas heated...
