IC 2944

The Running Chicken Nebula, Emission Nebula, Centaurus

February 2021. Observatorio El Sauce, Chile

IC 2944, also known as the Running Chicken Nebula or the λ Centauri Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. It features Bok globules, which are frequently a site of active star formation. However, no evidence for star formation has been found in any of the globules in IC 2944. Other designations for IC 2944 include RCW 62 and G42. There are a set of Bok globules discovered in IC 2944 by astronomer A. David Thackeray in 1950. These globules are now known as Thackeray’s Globules. In 2MASS images, 6 stars are visible within the largest globule. The region of nebulosity visible in modern images includes both IC 2944 and IC 2948, as well as the fainter IC 2872 nearby. IC 2948 is the brightest emission and reflection nebulae towards the southeast, while IC 2944 is the cluster of stars and surrounding nebulosity stretching towards λ Centauri. Other designations for IC 2872 include RCW 60, G39, and G40.
