Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).
There are models of two related universes that e.g. attempt to explain the baryon asymmetry – why there was more matter than antimatter at the beginning – with a mirror anti-universe. [78] [79] [80] One two-universe cosmological model could explain the Hubble constant (H 0) tension via interactions between the two worlds. The "mirror world ...
The universe also has vast regions of relative emptiness; the largest known void measures 1.8 billion ly (550 Mpc) across. [114] Comparison of the contents of the universe today to 380,000 years after the Big Bang, as measured with 5 year WMAP data (from 2008). [115] Due to rounding, the sum of these numbers is not 100%.
Named for its size, El Gordo ("the fat one") is the biggest cluster found in the distant universe (at its distance and beyond), at the time of discovery in 2011, with a mass of 3 quadrillion suns. The second most massive galaxy cluster next to El Gordo is RCS2 J2327 , a galaxy cluster with the mass of 2 quadrillion suns.
On 11 October 2022, the James Webb Space Telescope spent over 20 hours observing the long-studied Ultra Deep Field of the NASA/ESA Hubble Space Telescope for the first time. [ 18 ] The HDF galaxies contained a considerably larger proportion of disturbed and irregular galaxies than the local universe; [ 10 ] galaxy collisions and mergers were ...
