\n“Este cu adev\u0103rat un obiect remarcabil. \u015etiam c\u0103 astfel de obiecte trebuie s\u0103 existe, dar ele sunt at\u00e2t de estompate, \u00eenc\u00e2t sunt foarte greu de detectat”, a declarat David Kaplan, profesor la Universitatea Wisconsin-Milwaukee, autorul descoperirii.<\/p>\n
\nDavid Kaplan \u015fi colegii lui au descoperit aceast\u0103 “nestemat\u0103 stelar\u0103” cu ajutorul Green Bank Telescope (GBT), operat de National Radio Astronomy Observatory (NRAO), \u015fi folosind datele transmise de Very Long Baseline Array (VLBA).<\/p>\n
