A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
A 2017 paper suggests that IC 1101 has the largest core size of any galaxy with a core radius of around 4.2 ± 0.1 kpc (13.70 ± 0.33 thousand ly) by fitting a model to a Hubble Space Telescope (HST) image of the galaxy. This makes its core larger than the one observed in A2261-BCG, which is 3.2 kpc (10 thousand ly).
It is the most massive galaxy supercluster discovered so far. [19] Big Ring (2024) 1,300,000,000 Made up of galaxy clusters. Quipu (2025) 1,300,000,000 Contains 68 galaxy clusters. [20] (Theoretical limit) 1,200,000,000 Structures larger than this size are incompatible with the cosmological principle according to all estimates. However, whether ...
Nasa’s James Webb Space Telescope has found the two most distant galaxies ever seen, the space agency has said. The two galaxies are the earliest ever seen in the universe, dating back to when ...
This was announced as the most distant galaxy merger ever discovered. It is expected that this proto-cluster of galaxies will merge to form a brightest cluster galaxy, and become the core of a larger galaxy cluster. [150] [151] Galaxy protocluster SPT2349-56: z=4.3 (14 galaxies) This protocluster is located at 12.4 billion light years from the ...
This is also the first part of a trilogy of studies using Webb to analyze quasars at multiple points in the universe's history. These efforts could shed considerably more light on cosmic evolution ...
2013 – The galaxy Z8 GND 5296 is confirmed by spectroscopy to be one of the most distant galaxies found up to this time. Formed just 700 million years after the Big Bang, expansion of the universe has carried it to its current location, about 13 billion light years away from Earth (30 billion light years comoving distance).

The cosmological evolution of the void regions differs drastically from the evolution of the universe as a whole: there is a long stage when the curvature term dominates, which prevents the formation of galaxy clusters and massive galaxies. Hence, although even the emptiest regions of voids contain more than ~15% of the average matter density ...
