Comment:
Heart and Soul Nebulae are two clouds of glowing interstellar hydrogen gas. Hydrogen in the area is excited by radiation of the young stars in several open clusters visible in the image. Radiation and stellar wind from these stars is also responsible for hollowing out cavities in the central parts of the nebulae. This whole area has some 300 ly across and is 7500 ly distant from us.
