The Leo Ring is an immense primordial cloud of hydrogen and helium gas in orbit of two galaxies within the constellation of Leo.


Radio astronomers discovered the cloud in 1983. The GALEX satellite detected ultraviolet emissions that astronomers at Johns Hopkins University and the Carnegie Institution for Science interpret to indicate star creation in newly forming dwarf galaxies in a 19 February 2009 Nature paper.
