This mosaic of M31 merges 330 individual images taken by the Ultraviolet/Optical Telescope aboard NASA’s Swift spacecraft. It is the highest-resolution image of the galaxy ever recorded in the ultraviolet. The image shows a region 200,000 light-years wide and 100,000 light-years high (100 arcminutes by 50 arcminutes).

1. the universe regarded as an orderly, harmonious whole.

2. a complex orderly self-inclusive system.

According to Merriam-Webster, "Cosmos often simply means "universe". But the word is generally used to suggest an orderly or harmonious universe, as it was originally used by Pythagoras in the 6th century B.C. Thus, a religious mystic may help put us in touch with the cosmos, and so may a physicist...cosmic questions come from human attempts to find order in the universe.”

We would say the universe is an orderly cosmos, no question about it. As we all learn more about Nature and Life, this understanding will become commonplace.
