List of Abell clusters

The Abell catalogue is a catalogue of approximately 4.000 galaxy clusters with at least 30 members, almost complete to a redshift of z = 0.2. It was originally compiled by the American astronomer George O. Abell in 1958 using plates from POSS, and extended to the southern hemisphere by Abell, Corwin and Olowin in 1987. The name "Abell" is also commonly used as a designation for objects he compiled in a catalogue of 86 planetary nebulae in 1966. The proper designation for the galaxy clusters is ACO, as in "ACO 13", while the planetary-nebula designation is the single letter A, as in "A 39".

List of adjectivals and demonyms of astronomical bodies

The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies. For Classical Greco-Roman names, the adjectival and demonym forms normally derive from the oblique stem, which may differ from the nominative form used in English for the noun form. For instance, for a large portion of names ending in -s, the oblique stem and therefore the Eng ...

List of galaxy groups and clusters

This page lists some galaxy groups and galaxy clusters. Defining the limits of galaxy clusters is imprecise as many clusters are still forming. In particular, clusters close to the Milky Way tend to be classified as galaxy clusters even when they are much smaller than more distant clusters.

List of largest cosmic structures

This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year. This list includes superclusters, galaxy filaments and large quasar groups LQGs. The list characterizes each structure based on its longest dimension. Note that this list refers only to coupling of matter with defined limits, and not the coupling of matter in general as per example the cosmic microwave background, which fills the entire universe. All structures in this list are defined as to whether their presiding limits have been identified. There are some speculations about ...

List of fast radio bursts

This is a list of fast radio bursts. Items are listed here if information about the fast radio burst has been published. Although there could be thousands of detectable events per day, only detected ones are listed.

List of globular clusters

These are globular clusters within the halo of the Milky Way galaxy. The diameter is in minutes of arc as seen from Earth. For reference, the J2000 epoch celestial coordinates of the Galactic Center are R.A. 17 h 45 m 40.04 s, Dec. −29° 00′ 28.1″. A high proportion of globular clusters are located in the Ophiuchus and Sagittarius constellations, both of which lie in the direction of the galactic core.
