Different emission components of the nearby starburst galaxy NGC 253 were studied in X-rays, based on four XMM-Newton observations between 2000 and 2003. We find the ultra-luminous X-ray source NGC 253 ULX1 as a reccurent and anisotropically emitting stellar mass black hole Low Mass X-ray Binary. Prominent emission from hot gas is characterised by temperatures of 1.1-9.2x10
6 K in the disc and 1.1-3.4x10
6 K in the halo. Regions in the disc with active star forming show harder spectra than those with lower star forming activity. The halo emission is spatially and spectrally non-uniform. We present the first spatially resolved high-resolution X-ray spectroscopy of the nuclear outflow and derive temperatures for the predominantly collisionally ionised plasma. The O VIII emission line image of the nuclear region shows the hot wind emission for the first time directly.
