Melotte 15 is the central region of the Heart Nebula (IC 1805), some 7,500 light years away from us. Melotte 15 is a relatively small open cluster of stars some 1.5 million years old, some of them 50-times more massive than the sun, and surrounded by the interstellar cloud. The interesting shape of the gas filaments in Melotte 15 are created through wind and radiation from the stars in the cluster. Melotte 15 is responsible for the ionization of the hydrogen in the Heart Nebula giving it the red glow in the visual spectrum. The photo below is produced using narrowband imaging.
