“IC 1805: The Heart Nebula” is copyrighted by Toni Fabiani. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThe Heart Nebula, IC 1805, glows brightly in red hydrogen light, with hints of yellow sulfur and blue oxygen, resembling its namesake. At its core, the young stars of the open cluster Melotte 15 sculpt dramatic dust pillars. Their intense radiation erodes the surrounding gas and dust, illuminating this active star-forming region. It's a cosmic heart beating with the energy of new stars.
