This image shows the spiral galaxy NGC 691, captured in great detail using Hubble’s Wide-angle Camera 3 (WFC3). This galaxy is a member of the galaxy group NGC 691 named after it. It contains a cluster of gravitational galaxies located about 120 million light-years from Earth.
Hubble observed objects such as NGC 691 using various filters. Each filter only allows a certain wavelength of light to reach Hubble’s WFC3. Filtered images are then colored by experts who intelligently decide which color best corresponds to the wavelength of light from the astronomical object transmitted by each filter.
Combining color images from individual filters creates a full color image. This detailed process gives us a good understanding of the nature and appearance of these objects.
