Universe - Wikipedia
The universe is all of space and time [a] and their contents. [10] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of matter and energy, and the structures they form, from sub-atomic particles to entire galactic filaments.
Large Scale Structures - NASA Science
Galaxies, galaxy groups and clusters, superclusters, and galactic walls are arranged in twisting, threadlike structures called the cosmic web. The web forms as the gravitational attraction of the universe’s matter draws larger and larger objects together.
Universe - NASA Science
Discover the universe: Learn about the history of the cosmos, what it's made of, and so much more. Worlds beyond our solar system. In 2005, NASA’s Spitzer mapped a ring of dust around Vega, one of the brightest stars in the northern sky.
Mapping the Cosmic Web - NASA Science
This visualization is based on a scientific simulation of the growth of structure in the universe. The matter, dark matter, and dark energy in a region of the universe are followed from very early times of the universe through to the present day using the equations of gravity, hydrodynamics, and cosmology. The normal matter has been clipped to ...

JPL research on the Structure of the Universe covers a wide array of topics that address understanding the evolution of the universe beginning with the formation of the first galaxies and continuing until the present time.
Large Scale Structure - Center for Astrophysics
These galaxies fall into a pattern: the large-scale structure of the universe. This structure is a huge web shaped by gravity, with most galaxies and galaxy clusters lying along the strands.

2024年12月3日 · Lead author for one of the studies and a researcher at OzGrav and Monash University, Rowina Nathan, says the map provides an unprecedented glimpse into the structure of our universe.
The Development and Present Structure of the Universe
The standard model of Astronomy is supported by several experimental observations which prove the essential points of the Big Bang Theory. 6.1.1 The Expansion of the Universe. The American astronomer Edwin Powell Hubble (1889–1953) discovered in 1929 that the wavelengths of spectral lines emitted from distant galaxies are shifted to the red. Since he had measured …

2024年2月22日 · How Did Structure Form in the Universe? Astronomers observe considerable structure in the universe, from stars to galaxies to clusters and superclusters of galaxies. The famous "Deep Field Image" taken by the Hubble Space Telescope, shown below, provides a stunning view of such structure.
Structure of the Universe
What is the large-scale structure of the universe? What exactly are superclusters and filaments and voids? Let’s start by looking at galaxy groupings and move on to even larger structures.
