1930R. J. Trumpler in Lick Observatory Bull. XIV. 187/2 It seems worth while to examine the hypothesis that our Milky Way system..together with the two Magellanic Clouds and about a hundred globular clusters form a cluster of extra-galactic objects which we may call the ‘supercluster’. 1958Astron. Jrnl. LXIII. 260/2 The local super-cluster of galaxies is an irregular assembly of groups, clouds and clusters dominated by the Virgo cluster in its center. 1970Nature 19 Dec. 1137/1 Wolfe and Burbidge argue from these observations that super⁓clusters of galaxies..must definitely be ruled out. 1978Pasachoff & Kutner University Astron. i. 6 Before we could enlarge our field of view another 100 times we might see a supercluster—a cluster of clusters of galaxies. 1982Daily Tel. 1 Dec. 1/6 The largest-known object in the universe, a supercluster of millions of galaxies, has been discovered.

1960Soviet Astron. III. 910 We conclude that not only clustering, but also superclustering, is a general characteristic of the distribution of galaxies. 1971D. W. Sciama Mod. Cosmol. vii. 96 The suggested scale of their clustering would be much the same in relation to their separation as is the case for the clustering or super-clustering of galaxies. |
