Caption: Chandra's image of NGC 7027 represents the first detection of X-rays from this young planetary nebula that is about 700 years old. A bubble of 3 million degree Celsius gas with a length about a hundred times that of our solar system is shown in the image. The image is brighter to the upper right the side of the nebula nearest the Earth where there is less obscuring material to block the X-ray emission. NGC 7027 is the remains of a Sun-like star that has ejected much of its mass to expose its hot core. The X-rays are thought to be produced when a "fast" wind from the hot core collides with the "slow" wind that was ejected earlier during the star's red giant phase. This collision heats the matter to several million degrees so that it glows in X-rays.

Scale: Image is 22 arcsec on a side.
