Leo Cluster
galaxy cluster
The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.
A team of scientists decided to observe the Leo Cluster with the intention of creating a catalog of extended ionized gas (EIG) clouds. This data also led to the discovery of many star-forming parents (galaxies) within the cluster. These star-forming galaxies turned out to be very similar to those found in the neighboring Coma cluster. The EIGs in the Leo cluster, however, turned out to be longer in the Leo cluster than the Coma cluster. This likely means that the Leo cluster and its stars are probably younger than most comparable clusters in the universe and evolve at a different pace.
Most dense galaxy clusters are composed mostly of elliptical galaxies. The Leo Cluster, however, mostly contains spiral galaxies, suggesting that it is much younger than other comparable clusters, such as the Coma Cluster.
“Leo Cluster” enters the record as galaxy cluster. Crown Archives preserves that source wording while asking what Cluster, galaxy and cluster can confirm, complicate or overturn.
Why this record matters
“Leo Cluster” is worth following because a concise public description often conceals a longer documentary argument. Here, Cluster, galaxy and cluster provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q2636046. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1367.
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.
