The '''Soul nebula''' (Westerhout 5) is an [[emission nebula]] in the [[constellation]] of [[Cassiopeia]].<ref name=constellation-guide/> It forms a well known pair with the nearby [[Heart nebula]] (only 2.5 degrees) called the "Heart and Soul" nebula. These nebula are in fact connected via a bridge of [[gas]]. The nebula is also known as the Embryo nebula or IC 1848, the Index Catalogue designation of an [[open cluster]] contained within the nebula. The nebula is located near several interesting deep sky objects including the [[Fishhead nebula]] as well as the [[galaxies]] Maffei 1 and Maffei 2.<ref name=constellation-guide/>
==Properties and Structure==
With an apparent size of some 150 arc minutes, the nebula's distance of 7,500 [[light year]]s means it has a physical size of around 100 light years.<ref name=constellation-guide/> When the [[Heart nebula]] is included, the Heart and Soul nebula span around 300 light years of space. The nebula houses a few [[open star cluster]]s, their designations being CR 34, CR 632, CR 634 and IC 1848 which is also sometimes used to refer to the nebula itself. Also located near the nebula are three small [[emission nebula]]e, with designations IC 1871, IC 670, IC 669. [[Stellar wind]]s from [[star]]s within the nebula are producing pillars of gas and dust that point towards the centre of the nebula. Stars are also located at their tips. These pillars are thought to be around 10 light years long.<ref name=constellation-guide/> A large radio source is located in the nebulae. Designated Westerhout 5 (W5), it appears four times greater than the [[Moon]]. The appearance of the nebula in the radio portion of the [[electromagnetic spectrum]] follows a similar pattern to the optical.<ref>Kaifu, N.; Morimoto, M., Radio Observations of Four Diffuse H II Regions.
