In the middle of this little-known nebula called Gum 41, brilliant hot young stars are giving off energetic radiation causing the surrounding hydrogen to glow a characteristic red. The nebula is located 7300 light-years from Earth. Australian astronomer Colin Gum discovered it on photographs taken at the Mount Stromlo Observatory near Canberra, and included it in his catalogue of 84 emission nebulae, published in 1955. Gum 41 is actually one small part of a bigger structure called the Lambda Centauri Nebula, also known by the more exotic name of the Running Chicken Nebula.
