Ultra-faint dwarf galaxies have been discovered for the first time surrounding a Milky Way-sized galaxy, similar to those found within the Milky Way's neighborhood. According to findings recently presented at the 241st meeting of the American Astronomical Society, the identification of the fainte
Researchers discovered the first ultra-faint dwarf galaxies to be found around a spiral galaxy with the mass of the Milky Way that’s outside of the clustering of galaxies that includes the Milky Way and Andromeda. Pictured is one of the three galaxies, Scl-MM-dw5, with its stars clustered at center. The galaxies are estimated to be 12 billion years old, with nearly all their stars having formed in the early universe.
A team of scientists, headed by Burçin Mutlu-Pakdil, who is now a professor of physics and astronomy at, have uncovered three ultra-faint dwarf galaxies that are considered among the faintest galaxies found outside of the Local Group. The Local Group is a cluster of galaxies that includes the Milky Way and Andromeda. The newly discovered galaxies are located approximately 11.
UFDs are the least luminous and least chemically evolved galaxies known. Yet, they are the most dominated by dark matter, which is the mysterious form of matter thought to constitute most of the universe. For these reasons, astronomers consider UFDs to be pristine fossils of the early universe that could provide the best opportunities for studying the composition of the universe and the formation of its first galaxies.
