RCW 75 (catalogued as Gum 48a) is an active HII emission nebula and star-forming region located in the southern constellation of Centaurus. Situated roughly 6,500 light-years from Earth, it features a stunning "elephant trunk" dark nebula, brilliant ionised gas, and active embedded star clusters. At the tip of this trunk, radiation-driven implosions have formed faint blue reflection nebulae known as VdBH 60.
The nebula's glow is primarily powered by ‘Stock 16’, a very young open star cluster (only 3 to 6 million years old).
