understanding of how quickly galaxies in the early Universe evolve into the orderly galaxies of today\u2019s cosmos,\u201d Lucie Rowland, a doctoral student at Leiden University and first author of the study, said in the statement.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2bl9mfb0007356mmjluqyu2@published\"

Andrew Blain, a professor of astrophysics at the University of Leicester, who was not involved in the paper, said REBELS-25 is \u201ca bit unusual,\u201d but \u201cit\u2019s not a revolution.\u201d\n

individual examples would have been too faint to detect in a reasonable time, and a large enough sample of candidates could not be searched,\u201d he told CNN. \u201cALMA also reveals details finer than earlier telescopes.\u201d\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2bm1t87000j356m8ms9o4m7@published\"
