Alongside the well-known Heart Nebula, there can only be… the Soul Nebula.
It is a vast HII (ionized hydrogen) region about 7600 light-years away from us where there is a strong star formation. That framed is only the eastern section of the nebula, too large to fit completely within the field of view of the telescope in use.
