Observations of a region of the Galactic Center show an X-ray filament and cloud about 40 light years across (blue). These X-ray features are associated with a huge cloud of cold gas (shown as a dark area in the inset box) that is adjacent to large filamentary and shell-like structures that are bright sources of radio waves (red). The pullout on the lower left of the image shows the Chandra data. The X-ray emission is thought to be produced when energetic electrons from the radio filaments collide with the cold gas cloud, which has a mass one million times the mass of the Sun. This process of the bombardment of cold gas clouds with energetic electrons could explain the origin of the mysterious X-ray ridge along the plane of the Milky Way galaxy that was discovered nearly 30 years ago. A much larger field of view in radio light provides context for the X-ray data with spectacular filamentary structures arching like large claws and displayed in bright red. The image provides a multi-wavelength view of an area in our Galactic center that includes the Arches Cluster, located in the constellation Sagittarius.
