Widely recognised as being among the largest known stars, [21] radius decreased to ~500 R ☉ during the 2020 great dimming event. [75] R Horologii: 630 [60] L/T eff: A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun.
It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may actually be two or more companions orbiting too closely ...
Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion light ...
On January 11, 2013, the discovery of the Huge-LQG was announced by the University of Central Lancashire, as the largest known structure in the universe by that time.It is composed of 74 quasars and has a minimum diameter of 1.4 billion light-years, but over 4 billion light-years at its widest point.

The Saraswati Supercluster is one of the largest and most massive superclusters known, comparable to the massive Shapley Concentration in the nearby universe. The supercluster consists of 43 massive galaxy clusters, the most massive being Abell 2631 and ZwCL 2341.1+0000 respectively. [1]

2013 – The Hercules–Corona Borealis Great Wall, a massive galaxy filament and the largest known structure in the universe, was discovered through gamma-ray burst mapping. [ 19 ] [ 20 ] [ 21 ] 2014 – The Laniakea Supercluster , the galaxy supercluster that is home to the Milky Way is defined via a new way of defining superclusters ...
Hearts, a traditional card game , evolved from a game called Reverse (or Reversis), that was played in Europe from the 16th through the 19th centuries. In Reverse, the goal was to avoid capturing ...
