1.   As Verde explained, she and Heavens used statistics to analyze the shapes of the galaxy clusters in the sky.

2.   Dr. Licia Verde, an astronomer at Princeton and Rutgers Universities, analyzed the shapes of galaxy clusters.

3.   Hovering like giant street lights at the intersection of those disciplines are galaxy clusters containing gas so hot that it copiously emits X-rays visible to Chandra.

5.   In one case, a primeval blue galaxy appears in five different places in the sky, its image split by the steep curvature around a foreground galaxy cluster.

6.   In this case, he concluded, it is likely that some form of the superclusters existed before the galaxy clusters in them took their present shapes.

7.   Other astronomers reported observations showing that a supercluster in the constellation Aquarius consisted of two long filaments of connecting galaxy clusters.

8.   Surveying X-ray emissions, the Rosat spacecraft found several undetected galaxy clusters in the gravitational realm of one supercluster in the northern sky.

9.   Surveying X-ray emissions, the Rosat spacecraft found several previously undetected galaxy clusters in the gravitational realm of one supercluster in the northern sky.

10.   The X-rays, a signature of galaxy clusters, come from hot intergalactic gas, which is heated by collisions and mergers of galaxies.
