The Heart Nebula, an emissions nebula, owes its existence to the profound influence of nearby stars, which ionize the surrounding hydrogen gas. At its core lies the Melotte 15 open star cluster, where colossal stars, nearly 50 times the mass of our Sun, illuminate the cosmic canvas. This celestial wonder is located a staggering 7,500 light years from Earth and graces the constellation Cassiopeia. Presented in Hubble Palette with an astonishing 41 hours and 50 minutes of exposure time.
