In so doing, astronomers are able to see the earliest galaxies in the Universe and learn more about how they evolved over time. From this, they are not only able to see how large-scale structures (like galaxies and galaxy clusters) formed, but also the role played by dark matter.<\/p>\n<p>Most recently, an international team of scientists used the <a href=\"http:\/\/www.almaobservatory.org\/en\/home\/\">Atacama Large Millimeter-submillimeter Array<\/a> (ALMA) to observe the Universe when it was just 1.4 billion years old. What they observed was a \u201cprotocluster\u201d, a series of <a href=\"https:\/\/public.nrao.edu\/news\/2018-alma-megamerger\/#PRimage1\">14 galaxies located 12.4 billion light-years away<\/a> that were about to merge. This would result in the formation of a massive galaxy cluster, one of the largest objects in the known Universe.<\/p>\n<p>The study which described their findings, titled \u201c<a href=\"https:\/\/www.nature.com\/articles\/s41586-018-0025-2\">A massive core for a cluster of galaxies at a redshift of 4.3<\/a>\u201d, recently appeared in the journal <em>Nature. <\/em>The study was led by Tim Miller \u2013 an astronomer from Dalhousie University, Halifax, and Yale University \u2013 and included members from NASA\u2019s Jet Propulsion Laboratory, the <a href=\"https:\/\/www.eso.org\/public\/\">European Southern Observatory<\/a> (ESO), Canada\u2019s <a href=\"https:\/\/www.nrc-cnrc.gc.ca\/eng\/\">National Research Council<\/a>, the <a href=\"https:\/\/www.cfa.harvard.edu\/\">Harvard-Smithsonian Center for Astrophysics<\/a>, the <a href=\"https:\/\/public.nrao.edu\/\">National Radio Astronomy Observatory<\/a>, and multiple universities and research institutions.<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.universetoday.com\/139112\/astronomers-see-a-pileup-of-14-separate-galaxies-in-the-early-universe\/\">https:\/\/www.universetoday.com\/139112\/astronomers-see-a-pileu...-universe\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Looking deep into the observable Universe \u2013 and hence, back to the earliest periods of time \u2013 is an immensely fascinating thing.
