  2. Galaxy filament - Wikipedia

    en.wikipedia.org/wiki/Galaxy_filament

    In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...

  3. Chronology of the universe - Wikipedia

    en.wikipedia.org/wiki/Chronology_of_the_universe

    Therefore, the cosmic microwave background is a picture of the universe at the end of this epoch including the tiny fluctuations generated during inflation (see 9-year WMAP image), and the spread of objects such as galaxies in the universe is an indication of the scale and size of the universe as it developed over time.

    The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed at that time. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is ...

  5. The universe is getting hotter as it gets older — here’s why

    The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time. Utilizing a phenomenon ...

    An early direct evidence for this cosmic web of gas was the 2019 detection, by astronomers from the RIKEN Cluster for Pioneering Research in Japan and Durham University in the U.K., of light from the brightest part of this web, surrounding and illuminated by a cluster of forming galaxies, acting as cosmic flashlights for intercluster medium ...

    en.wikipedia.org/wiki/How_the_Universe_Works

    [1] [2] With the use of computer-generated imagery (CGI) and visual effects, each episode presents and narrates a topic about the universe (e.g.: the origin of the universe, the formation and the evolution of the Solar System, and the origin and behavior of life), which then are complemented with scientific insights from leading scientists of ...

  8. Physical cosmology - Wikipedia

    en.wikipedia.org/wiki/Physical_cosmology

    Physical cosmology is a branch of cosmology concerned with the study of cosmological models. A cosmological model, or simply cosmology, provides a description of the largest-scale structures and dynamics of the universe and allows study of fundamental questions about its origin, structure, evolution, and ultimate fate.

  9. Missing baryon problem - Wikipedia

    en.wikipedia.org/wiki/Missing_baryon_problem

    Generated image of the cosmic web which contains warm-hot regions where the missing baryons have been detected. [11] Prior to 2017, baryons were found to be distributed 10% inside galaxies, 50–60% in the circum-galactic medium, and 30–40% unaccounted, therefore accounting for about 70% of theoretical predictions.
