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.
