Description

M57, the Ring Nebula, the corpse of a red giant star. This remnant is located ~2000 light years away in the constellation Lyra. M57 is the result of a red giant shedding its outer layers as it progresses through the final stages of its existence. The remaining white dwarf star at its center energizes the expelled gases causing the atoms to glow.
