Peering into the remote compass of space is like turning back metre . The lustrous red orbs at the plaza of this simulacrum are galaxies , as they existed 8.5 billion years ago in a far-off turning point of the universe . Together , they mold a clustering that grew to mind - boggling proportionality long before the birth of our Solar System .
“ free-base on our understanding of how Galax urceolata clusters farm from the very beginning of our world , this clustering should be one of the five most massive in existence at that time , ” said the Jet Propulsion Laboratory ’s Peter Eisenhardt , carbon monoxide gas - author on a new bailiwick describing the cosmic behemoth .
Galaxy clusters , closely - knit groups of G of individual Galax urceolata , are the natural outcome of gravitational strength playing out on fantastic scales . Just as planets spiral around a central star and stars congregate at astronomic centers , so too will galaxies find themselves drawn together by the irresistible tug of gravity . The bigger a cluster gets , the heavy its pull on the palisade space .
This particular clump , fitly dubbed a “ Massive Overdense Object ” ( MOO ) , was first detect by the Wide - field Infrared Survey Explorer ( WISE ) , in an all - sky survey performed in 2010 - 2011 . Remote object like moo leave a distinct signature in quad ; their lightwaves becoming longer and more stretched as they traverse impossible cosmic distance . From the perspective of an infrared scope on Earth , they ’re vivid , redshifted roses in a field of force of daisies .
After it first cropped up in the WISE dataset , astronomers used a numeral of other scopes and observatories to flesh out our portrait of MOO . NASA ’s Spitzer Space Telescope allowed us to visualise the clump in more detail , while the W.M. Keck Observatories and Gemini Observatory on Mauna Kea in Hawaii sharpened the object ’s distance from house to a exact 8.5 billion light age .
If you really need a stark admonisher of our cosmic insignificance , data collected with the CARMA telescope in California was used to estimate the cluster ’s size . That endearing figure of speech you ’re await at represents an object a quadrillion sentence the mass of our Sun . Somebody well manufacture FTL drives soon if we ’ve any hope of exploring it .
