Natural Color:
Galaxy ESO 510-G13
We constructed this image of the galaxy ESO 510-G13 from three
different black-and-white images representing red light, green
light, and blue light from the galaxy. The colors assigned to
each of these images were chosen to simulate the actual colors
of the galaxy.
Much of the galaxy appears whitish because it contains stars
of many different colors, which combine to create a white appearance
in the final image.
However, near the dark band of dusty gas slicing through the
middle of this galaxy, the starlight appears redder because the
dusty gas blocks blue light more effectively than red light.
This effect is even clearer in the individual black-and-white
images. Note that the dust band appears darkest in the leftmost
black-and-white image, which was taken through a blue filter.
