-a supercluster is a ‘large group’ of smaller ‘galaxy clusters’ (or ‘galaxy groups’), which is among the largest-known structures of the ‘cosmos’-
.
(the ‘milky way’ is part of the ‘local group galaxy cluster’ (that contains more than 54 galaxies), which in turn is part of the “laniakea supercluster”)
(this supercluster spans over ‘500 million light-years’, while the ‘local group’ spans over ’10 million light-years’)
(the # of ‘superclusters’ in the observable universe is estimated to be ’10 million’)
(‘galaxies’ are grouped into ‘clusters’ instead of being dispersed randomly)
(‘clusters’ of galaxies, in turn, are grouped together to form ‘superclusters’)
(typically, ‘superclusters’ contain dozens of individual ‘clusters’ throughout an area of ‘space’ about ‘150 million light-years across’)
(unlike ‘clusters’, most ‘superclusters’ are not bound together by ‘gravity’)
(the ‘component clusters’ are generally shifting away from each other due to the “hubble flow”)
(the ‘milky way galaxy’ falls within the ‘local group’, which is a ‘poor’ (?) + ‘irregular’ cluster of ‘galaxies’)
(‘poor clusters’ may contain only a ‘few dozen galaxies’, as compared to ‘rich clusters’ with ‘hundreds’ (or even ‘thousands’))
(“the local group” is in the ‘local supercluster’ (also known as the ‘virgo supercluster’), which has a diameter of ‘100 million light-years’)
(“the local supercluster” contains a total of about 1015 times the mass of the ‘sun’)
(the biggest cluster in the ‘observable universe’ is called the “great attractor”)
(its ‘gravity’ is so strong that the ‘local supercluster’ (including the ‘milky way’), is moving in a direction towards it at a rate of ‘several hundred kilometers per second’)
(the biggest supercluster outside the ‘local universe’ is the “perseus–pegasus filament”)
.
(it contains the ‘perseus supercluster’ and it spans about a ‘billion light-years’, making it one of the largest known structures in the ‘universe’)
