description IC 2948 (Lambda Centauri Nebula) Overview
IC 2948, commonly referred to as the Lambda Centauri Nebula or the Running Chicken Nebula, is a bright emission cloud located in the constellation Centaurus. It is an H II region ionized by the radiation from nearby hot stars, creating a distinct reddish glow. The nebula is highly notable among astronomers for containing dense, collapsing Bok globules, which were extensively observed by astronomer A.D. Thackeray.
These dark molecular clouds are potential sites of new star formation and are actively studied by astrophysicists.
help IC 2948 (Lambda Centauri Nebula) FAQ
What is the Lambda Centauri Nebula?
IC 2948 is a bright emission cloud in the constellation Centaurus. It is also called the Running Chicken Nebula.
Why does IC 2948 glow red?
IC 2948 is an H II region, meaning hydrogen gas ionized by nearby hot stars produces its glow. The ionized gas gives the nebula its distinctive reddish appearance.
Why is IC 2948 called the Running Chicken Nebula?
The nickname comes from the shape observers can see in the nebula's bright and dark regions. Its formal catalog designation is IC 2948.
What powers the Lambda Centauri Nebula's light?
Radiation from nearby hot stars ionizes the surrounding hydrogen gas. That process makes IC 2948 an emission nebula rather than a reflection nebula.
