Abstract
We present the first high-spatial-resolution X-ray images and spectra of the Omega Nebula, obtained in a single 40 ksec observation with the Advanced CCD Imaging Spectrometer aboard the Chandra X-ray Observatory in 2002 March. This rich, high-mass star-forming region reveals a complex mix of point sources and diffuse X-ray emission. The OB association is resolved at the arcsecond level into more than 900 sources. Soft diffuse X-ray emission pervades the H II region and is resolved from the point source population. This extended emission is most likely from the fast O-star winds that thermalize and shock the surrounding media.
