IC 2944
H II region and open cluster in the constellation Centaurus
IC 2944, also known as the Running Chicken Nebula, the Lambda Centauri 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, G40 and G42.
The ESO Very Large Telescope image on the right is a close up of 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. IC 2944 gets the nickname "Running Chicken Nebula" from a group of stars that resemble a running chicken.
This brief starts where responsible research should: with the source description of “IC 2944” as h II region and open cluster in the constellation Centaurus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as h II region and open cluster in the constellation Centaurus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 16, 2025. The linked authority identifier is Q79642350. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
