The universe is a big place , and it ’s full of big matter . Planets , star topology , galaxies and clusters of galaxies extend upward on ever - more - monumental scale . Here we marvel at some of the phonograph record holders in dissimilar cosmic categories , perhaps feeling humiliate by the universe ’s ability to develop entities of incredible sizing and grandeur .
Largest exoplanet: GQ Lupi b
uranologist were n’t trusted what to make of the mysteriousGQ Lupi bwhen it was first discovered in 2005 . orbit a young star around two and a one-half times farther than Pluto is from the sunshine , the fellow object seemed to be either a major planet or a dark-brown dwarf , which is actually a case of small virtuoso . Subsequent reflexion have yet to sack up the muddiness , but the best estimation hint GQ Lupi bhas a radius around 3.5 timesthat of Jupiter , mean that if it is an exoplanet , it ’s the largest ever found .
Largest star: UY Scuti
UY Scuti is a hypergiant star with a radius that ’s around 1,700 time larger than the sun , making it thebiggest known ace in the universe . If someone were to place UY Scuti at the centre of thesolar system , its boundary would extend just beyond the orbit of Jupiter . gasoline and dust cyclosis from the star would extend even further out , beyond the orbit of Pluto , or around 400 times the Earth - sunlight distance .
Largest Nebula: The Tarantula Nebula
Both the largest known nebula and most participating star - forming region in our local galactic region , the Tarantula Nebula stretch formore than 1,800 light - yearsat its long dyad . Also know as 30 Doradus , the object islocated 170,000 light - yearsfrom Earth in the Large Magellanic Cloud , a small satellite coltsfoot that revolve ourMilky Way . Rather than a killer arachnid , this Tarantula is a stellar nursery — within its beautiful folds of gas and dust young hotshot are being carry .
Largest empty spot: Supervoid in Eridanus
In 2004 , astronomers noticed a gigantic area of empty space in function created byNASA ’s Wilkinson Microwave Anisotropy Probe ( WMAP ) satellite , which scan in dainty detail the cosmic microwave background , or the leftover radiation from the Big Bang . The spot , which spans 1.8 billion light - age across , according to Vice , is strangely devoid of mavin , gas , dust and even dark matter . While they have seen old void , researchers rest confused as to how exactly one of this size and exfoliation formed .
Largest galaxy: IC 1101
Our Milky Way beetleweed is around 100,000 faint - age across , but that ’s fair mean for a spiral galax . In comparison , the largest known Galax urceolata , phone IC 1101 , is 50 time larger and about 2,000 times more massive than our astronomic nursing home . Stretching for an impressive 5.5 million light - year , IC 1101 is so big that , if placed where the Milky Way is now , its edge would reach past our near galactic neighbour , Andromeda .
Largest black hole: TON 618
Supermassive black fix are thought to lurk in the center of every galaxy and can time in at many millions of times the mass of the Sunday . But the enceinte known fatal hole can be found powering a removed quasar — gigantic target in the former universe throw up out insane amounts of radiation . This one , know as TON 618 , has an estimated mass of 66 billion Sunday , according to a assertion .
Largest galactic farts: Fermi Bubbles
In 2010 , uranologist using the Fermi space telescope discovered colossal structures emerging from the Milky Way . These massive blob , which can only be seen in sure wavelengths of light , are a towering 25,000 light - years tall ( a stern of the Milky Way ’s width ) . Researchersbelieve the bubblesare the answer of an ancient eating delirium that our galaxy ’s fundamental black hole experienced , result in enormous belches of Department of Energy .
Largest single object: Protocluster SPT2349-56
Back when the universe of discourse was only a one-tenth of its current years , 14 beetleweed began crashing together and forming the most monumental known gravitationally bind cosmic object , protocluster SPT2349 - 56 . Squeezed together in a space that ’s only about three times as big as our Milky Way galax , this megamerger will eventually combine into a single Galax urceolata weighing 10 trillion times the mass of the sunshine . Additional observation have revealed that around 50 additional galaxies border the social system , which will settle into a gigantic target bang as a astronomical clustering , in which many galaxies orbit one another .
Largest galactic collection: Shapley Supercluster
Astronomer Harlow Shapley discovered a colossal collection of galaxies in the thirties that now bears his name . Containing more than 8,000 Galax urceolata and with a slew of more than 10 million billion meter that of the Lord’s Day , the Shapley Supercluster is the big structure in the local universe , concord to the European Space Agency .
Largest supercluster: Laniakea Supercluster
Our whitish Way is just a tiny member of a giant collection of aggregation of coltsfoot get laid asthe Laniakea Supercluster . Though it has no stately boundaries , astronomers estimate that it contains around 100,000 extragalactic nebula with a full mint about 100 million billion times that of the Sunday , and stretches for more than 520 million light - geezerhood across .
Largest quasar collection: Huge-LQG
The distant mordant - hole - power superbright objects known as quasars are already mighty large . But sometimes , quasar can number together into clusters , with the largest one imaginatively named the Huge - LQG ( for immense Large Quasar Group ) . Containing 73 quasi-stellar radio source and an estimated hatful of 6.1 quintillion ( that ’s a 1 followed by 18 zeros ) suns , the colossal cosmic collection is intend to be 4 billion light - years across at its biggest span , allot to The Atlantic .
Largest thing in the universe: Hercules-Corona Borealis Great Wall
By represent the emplacement of gamma - ray bursts — momentary but powerful explosions that occur when a massive mavin die — stargazer reveal what is often considered to be the large know entity in the macrocosm : the Hercules - Corona Borealis Great Wall . The target is 10 billion light - years across and could contain 1000000000000 of galaxies . The Great Wall was first discovered in 2013 when surveys testify gamma - ray specially concentrate about 10 billion light - years aside in the direction of the Hercules and Corona Borealis constellations .
