NGC 6863 is a planetary nebula located in the constellation Sagittarius. It is approximately 3,000 light-years away from Earth and is known for its bright, colorful appearance. The nebula is formed from the outer layers of a dying star that has shed its material, creating a glowing shell of gas and dust. The central star of NGC 6863 is a hot, luminous object that emits ultraviolet radiation, causing the surrounding gas to ionize and emit light. This nebula is part of a larger category of astronomical objects known as planetary nebulae, which are important for understanding stellar evolution and the life cycle of stars.
