Baryon
A baryon is a composite subatomic particle made up of three quarks (a triquark, as distinct from mesons, which are composed of one quark and one antiquark).

CfA Redshift Survey
The Center for Astrophysics (CfA) Redshift Survey was the first attempt to map the large-scale structure of the universe.

CMB cold spot
The CMB Cold Spot or WMAP Cold Spot is a region of the sky seen in microwaves that has been found to be unusually large and cold relative to the expected properties of the cosmic microwave background radiation (CMBR).

Coma Filament
Coma Filament is a galaxy filament.

Cosmic string
Cosmic strings are hypothetical 1-dimensional topological defects which may have formed during a symmetry breaking phase transition in the early universe when the topology of the vacuum manifold associated to this symmetry breaking was not simply connected.

Dark matter
Dark matter is a theorized form of matter that is thought to account for approximately 80% of the matter in the universe, and about a quarter of its total energy density.

Galaxy
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter.

Galaxy filament
The distribution reveals fine, filamentary structures.

Hercules–Corona Borealis Great Wall
Hercules–Corona Borealis Great Wall or the Great GRB Wall.

Interstellar medium
In astronomy, the interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy.

John Huchra
John Peter Huchra (December 23, 1948 – October 8, 2010) was an American astronomer and professor.

Lambda-CDM model
The ΛCDM (Lambda cold dark matter) or Lambda-CDM model is a parametrization of the Big Bang cosmological model in which the universe contains a cosmological constant, denoted by Lambda (Greek Λ), associated with dark energy, and cold dark matter (abbreviated CDM).

List of largest cosmic structures
This is a list of the largest cosmic structures so far discovered.

Margaret Geller
Margaret J. Geller (born December 8, 1947) is an American astrophysicist at the Harvard–Smithsonian Center for Astrophysics.

Milky Way
The Milky Way is the galaxy that contains our Solar System.
New!!: CfA2 Great Wall and Milky Way · See more »
Observable universe
The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth at the present time, because electromagnetic radiation from these objects has had time to reach Earth since the beginning of the cosmological expansion.

Redshift survey
In astronomy, a redshift survey is a survey of a section of the sky to measure the redshift of astronomical objects: usually galaxies, but sometimes other objects such as galaxy clusters or quasars.

Sloan Great Wall
The Sloan Great Wall (SGW) is a cosmic structure formed by a giant wall of galaxies (a galaxy filament).

United States
The United States of America (USA), commonly known as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions.
