RCW 79 is an emission nebula in the constellation Centaurus. A cosmic bubble of gas and dust, RCW 79 has grown to about 70 light-years in diameter, blown by the winds and radiation from hot young stars. A good 17 thousand light-years away in the grand southern constellation Centaurus, the expanding nebula itself has triggered star formation as it plows into the gas and dust surrounding it. The nebula is estimate to be 2.0 – 2.5 million years old. It surrounds a central cluster of hot massive stars, with the hottest having spectral types of O4-5.
