This image includes the spiral galaxy NGC 691
Hubble monitors objects such as NGC 691 using a set of filters. Each filter allows only certain wavelengths of light to reach Hubble’s WFC3. The resulting filtered images are colored by specialists who make an informed choice of which color best matches the wavelengths of light from the astronomical object that are transmitted by each filter.
Combining color images from individual filters creates a full-color image. This detailed process gives us an extremely good idea of the nature and appearance of these objects.
