IC 1805, also known as the Heart Nebula, is a bright emission nebula located in the constellation Cassiopeia. It is approximately 7,500 light-years away from Earth and is part of a larger star-forming region known as Westerhout 5. The nebula gets its name from its heart-like shape, which is formed by the intricate patterns of gas and dust. The Heart Nebula is home to several young, massive stars that emit strong ultraviolet radiation, causing the surrounding gas to glow. This region is rich in stellar activity and is often studied by astronomers to understand the processes of star formation and the evolution of nebulae in the universe.
