About this Image

Unlike optical and ultraviolet images in which extinction by dust affect interpretation of optical images and in which a considerable fraction of the continuum emission is due to dust-scattered light, this image shows a true distribution of ionized gas. This picture shows the Trapezium region in red and its immediate surroundings such as the ionized "bar".
