Galaxy NGC 4579 was captured by the Spitzer Infrared Nearby Galaxy Survey,
or Sings, Legacy project using the Spitzer Space Telescope's infrared
array camera. In this image, the red structures are areas where gas and
dust are thought to be forming new stars, while the blue light comes from
mature stars. This image is a 4-channel, false-color composite, where blue
indicates emission at 3.6 microns, green corresponds to 4.5 microns, and
red to 5.8 and 8.0 microns. The contribution from starlight (measured at
3.6 microns) in this picture has been subtracted from the 5.8 and 8 micron
images to enhance the visibility of the dust features.
