We report the detection of well resolved , extended X-ray emission from the young planetary nebula BD +30 ^ { \circ } 3639 using the Advanced CCD Imaging Spectrometer ( ACIS ) aboard the Chandra X-ray Observatory .
The X-ray emission from BD +30 ^ { \circ } 3639 appears to lie within , but is concentrated to one side of , the interior of the shell of ionized gas seen in high-resolution optical and IR images .
The relatively low X-ray temperature ( T _ { x } \sim 3 \times 10 ^ { 6 } K ) and asymmetric morphology of the X-ray emission suggests that conduction fronts are present and/or mixing of shock-heated and photoionized gas has occurred and , furthermore , hints at the presence of magnetic fields .
The ACIS spectrum suggests that the X-ray emitting region is enriched in the products of helium burning .
Our detection of extended X-ray emission from BD +30 ^ { \circ } 3639 demonstrates the power and utility of Chandra imaging as applied to the study of planetary nebulae .
