Dwarf galaxyOr dwarf galaxies (Dwarf Galaxy) are smaller galaxies. The population of the stars is less compared to our own Milky Way galaxy alone.sphereOf dwarf galaxies there are a few billion. While the Milky Way’s star population is hundreds of billions of stars.
But dwarf galaxies still have a type that is Extra small dwarf galaxies (Ultra-Compact Dwarf galaxy-UCDs) there are only about 100 million stars. Most recently, a team of experts from many institutions. Led by astronomers at the University of Groningen. In the Netherlands The findings report for the discovery of 44 new ultra-small dwarf galaxies after analyzing data from the Fornax Deep Survey (FDS) and the total sky survey in the southern sky. It also uses a data set from the Vista Telescope to observe rays under red and light.
Astronomers say that These dwarf galaxies are likely members of the Fornax Galaxy Cluster, located about 65 million light-years from Earth, previously detected.Dwarf galaxiesThe ultra-small size of the cluster of 61 such galaxies, the team believes, that these ultra-compact dwarf galaxies may provide important insights into the formation and evolution of galaxies in the universe.
