We report the detection of well resolved, extended X-ray emission from the young planetary nebula BD +30o 3639 using the Advanced CCD Imaging Spectrometer aboard the Chandra X-ray Observatory. Our Chandra imaging observation provides vivid evidence for the presence of a so-called ``hot bubble'' at the core of this planetary nebula. Such a structure has long been predicted by interacting winds models of planetary nebulae evolution. The X-ray emission from BD +30o 3639, though evidently asymmetric, is roughly similar in diameter ( ~ 5'') and morphology to the ring of ionized emission seen in high-resolution optical and radio images. Our detection of extended X-ray emission from BD +30o 3639 demonstrates the power and utility of Chandra imaging as applied to the study of planetary nebulae. This research is supported by a NASA Chandra X-ray Observatory grant to Rochester Institute of Technology.
