  "summary": "Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been discovered in the vicinity of the Milky Way, in what is called the Local Group, but also, and in large quantities, at greater distances, where current instrumentation cannot…",
