Wolf-Rayet Nebula RCW 104
RCW 104 is a very faint Emission Nebula in the southern constellation of Norma. It is generated by the socalled Wolf-Rayet star WR 75. These kind of stars are very massive and speed rapidly through their astrophysical life, while emitting tremendous star winds, thus exciting complex emission nebulae in the surrounding gas.
