NGC 253

• NGC 253 is a Spiral galaxy of type Sc(s) in the Sculptor Group. An image of each wavelength region can be viewed by clicking on each small image below. The X-ray, Radio and Infrared images also have a contour outline that shows the edge of the optical galaxy for comparison.
• NOTE: The IRAS 60 micron image is affected by an instrumental effect. The faint spurs and extensions at large radii are spurious.
