NGC_2021 is a bright emission nebula located in the constellation of Lepus. It is part of a larger complex of star-forming regions and is known for its vivid colors, which are produced by the ionization of gas by nearby young stars. This nebula is approximately 1,500 light-years away from Earth and spans about 30 light-years across. NGC_2021 is often studied by astronomers to understand the processes of star formation and the dynamics of interstellar gas and dust.
