The Hubble Space Telescope has spotted a mysterious, solitary dwarf galaxy - a type that is smaller and messier than its cosmic cousins and lacks the majestic swirl of a spiral or the coherence of an elliptical. The galaxy UGC 4879 consists of a scattered drizzle of stars and is very isolated. Studies of UGC 4879 have shown a significant amount of star formation in the first four billion years after the Big Bang. The reason for this behaviour, however, remains mysterious, and the solitary galaxy continues to provide ample study material for astronomers looking to understand the complex mysteries of star birth throughout the universe. The galaxy's isolation means that it has not interacted with any surrounding galaxies, making it an ideal laboratory for studying star formation uncomplicated by interactions with other galaxies.
