IC 1848, the Fetus Nebula in Cassiopeia, lies at a distance of about 6500 light years from Earth as determined by the two open clusters embedded within its nebulosity, Collinder 33 and 34. The small nebulous patch detached from main body of IC 1848 along its left side is IC 1871.
The open star clusters formed about a million years ago from the material of the nebula. Winds and ultraviolet light from these young stars are excavating a cavity in the cloud. Parts of the cloud that are more dense than their surroundings are being eroded more slowly and form giant towers, or pillars of dust and gas, which all point toward the central star cluster. Material at the interior edges of the cavity is also being compressed by the winds and radiation from the star cluster. This triggers new star formation in those areas. The pillars inside the Soul Nebula are each about 10 light-years tall and have stars forming at their tips. Credit: NASA/JPL-Caltech/WISE Team.

This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".
