An open cluster of massive hot blue super-giant stars can be found near the center of IC 1805 – more commonly referred to as the Heart Nebula. Shown in the upper right quadrant of this image the
fierce stellar winds from these young stars have blown an enormous bubble within the parent HII nebula. These winds have also sculpted the dust clouds within which other stars are forming.
This is a narrowband image which captures ionized hydrogen, oxygen and sulfur atoms.
