This is the Hercules galaxy clustering , site relatively tight to us at just 500 million light - year off . But the direction its galaxies are clash with each other pull in it look like a throwback to the chaos of the early creation .
This unexampled double from the European Southern Observatory devote us our best look yet at this unusual clump . Its overall pattern is very different from nearby extragalactic nebula clusters , and its member galaxies are generally immature and still forming hotshot , with none of the big , ancient elliptical galaxies that are typical in the clusters around it . you may see a few lesson of the on-going galaxy mergers in the image below .
The absence seizure of prolate galaxies is a major pourboire - off that this is still a very young cluster . That ’s because it does n’t matter what types of wandflower initially get together to form the bunch – say , a bunch of spiral galaxies like our own whitish Way – as the never-ending collisions between wandflower twist them out of their original contour and strip aside the gas needed for continued star formation . The solvent is a mature bunch full of giant egg-shaped and irregular galaxy , and that ’s not what we see here in the Hercules bunch .
mightily now , the Hercules cluster is merging together three humble cluster and a clump more random groups of coltsfoot . But even that gargantuan task still pales in comparison to the even larger process going on around it . The total Hercules Cluster is slow merging with other nearby extragalactic nebula bunch to organize one monumental supercluster , which is one of the most stupendous structures in the creation .
