- The Local Group is the galaxy group that includes the Milky Way. It has a total diameter of roughly 3 megaparsecs (10 million light-years; 9×1022 metres), and a total mass of the order of 2×1012 solar masses (4×1042 kg). It consists of two collections of galaxies in a “dumbbell” shape: the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other. The two collections are separated by about 800 kpc (3×106 ly; 2×1022 m) and are moving toward one another with a velocity of 123 km/s. The group itself is a part of the larger Virgo Supercluster, which may be a part of the Laniakea Supercluster. The exact number of galaxies in the Local Group is unknown as some are occluded by the Milky Way; however, at least 80 members are known, most of which are dwarf galaxies.
- Psychological fiction (Wikipedia)
In literature, psychological fiction (also psychological realism) is a narrative genre that emphasizes interior characterization and motivation to explore the spiritual, emotional, and mental lives of its characters. The mode of narration examines the reasons for the behaviours of the character, which propel the plot and explain the story. Psychological realism is achieved with deep explorations and explanations of the mental states of the character’s inner person, usually through narrative modes such as stream of consciousness and flashbacks.
