Due to the accelerating expansion of the universe, the individual clusters of gravitationally bound galaxies that make up galaxy filaments are moving away from each other at an accelerated rate; in the far future they will dissolve. [2] Galaxy filaments form the cosmic web and define the overall structure of the observable universe. [3] [4] [5]
A map of galaxy voids. The structure of the Universe can be broken down into components that can help describe the characteristics of individual regions of the cosmos. These are the main structural components of the cosmic web: Voids – vast, largely spherical [6] regions with very low cosmic mean densities, up to 100 megaparsecs (Mpc) in ...
The observable universe is a spherical region of the universe consisting of all matter that can be observed from Earth; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.
A map of the superclusters and voids nearest to Earth. A supercluster is a large group of smaller galaxy clusters or galaxy groups; [1] they are among the largest known structures in the universe.
Extraordinary new scientific instruments are churning out trailblazing data, ready to reshape how scientists view the cosmos. A prime example is the European Space Agency’s wide-angle Euclid ...
An MeerKAT image of the Galactic Center showing a number of filaments Radio image of a number of parallel filaments in the Galactic Center; Sagittarius A*, the Milky Way's central black hole, is located in the bright region in the bottom right [1] [2] Nonthermal radio filaments from the 4'' resolution MeerKAT mosaic; oriented vertically for space; scales given assuming a distance of 8.2 kpc
The European Space Agency's Planck satellite has been gathering data since its launch in 2009, slowly building up a map of the cosmic microwave background radiation -- a distant remnant of the Big ...
