NGC 1569 Composite Optical/X-ray
image
This image illustrates the relationship between starlight, warm, and hot gas in the dwarf galaxy NGC 1569, which is undergoing a burst of star formation. The green color shows X-rays from multimillion degree Celsius gas heated by shock waves. Red shows optical, or visible, light from warm gas (tens of thousands of degrees Celsius), heated by ultraviolet light from massive stars. Large loops of the warm gas can be seen extending above and below the disk of the galaxy. The bright orange disk is glowing primarily due to visible light from stars with temperatures of thousands of degrees, but warm and hot gas are also present.

NGC 1569 Illustration
This illustration depicts the orientation of NGC 1569 and the line of sight from which Chandra observed it. Most of the X-ray halo emanates from the central disk of the galaxy, which is inclined at an angle of 60 degrees to Earth. This means that the northern lobe of X-ray emission from NGC 1569 is largely blocked from Chandra's view, while the southern lobe appears to be more prominent.
