The Heart Nebula (IC 1805), located 7,500 light-years away in the constellation Cassiopeia, is a vast emission nebula shaped like a cosmic heart. Its glowing hydrogen gas, sculpted by stellar winds, surrounds the young open cluster Melotte 15, home to massive, bright stars. Dark dust lanes weave through the nebula, adding depth and contrast. This celestial masterpiece is a vibrant star-forming region, where intense radiation and winds shape the surrounding clouds of gas and dust.
