A Dwarf Starburst Galaxy


NGC 1705 is a oddball irregular dwarf galaxy undergoing a starburst. It’s about 17 million light-years from the Earth in the constellation Pictor. Dwarf galaxies were probably the first systems to collapse and start forming stars in the early universe. They represent the building blocks from which more massive objects (such as spiral and elliptical galaxies) were formed through mergers. The remaining dwarf galaxies are thought to be the leftovers of the galaxy-formation process.
