The Leo I Dwarf Galaxy is a small, irregular galaxy located about 820,000 light-years from Earth in the constellation Leo. It is part of the Local Group of galaxies, which includes the Milky Way and Andromeda. Discovered in 1950, Leo I is notable for its low luminosity and sparse population of stars. This galaxy is classified as a dwarf spheroidal galaxy, meaning it has a round shape but lacks significant gas and dust. Leo I contains older stars and is thought to have formed early in the universe's history, making it an interesting subject for studying galaxy formation and evolution.
