IC 2944, also known as Running Chicken Nebula, in reallity is an open cluster embedded in a emission nebula found in constellation Centaurus, near Lambda Centauri. The nebula shows some Thackeray Globes, which are associated to an area of active star formation rgion, although there is no evidence of this fact due to the erosion caused by the intensse radiation coming from the closeby young stars.
Anyway, it is still know very little about their origin and nature, except that they are generally associated with areas of HII with a tendency for star formation.
IC 2944 is filled with gas and dust that is illuminated and heated by a loose cluster of massive stars. These stars are much hotter and much more massive than our Sun.
