Bu fevkal\u00e2de manzara, g\u00fc\u00e7l\u00fc k\u00fctle\u00e7ekimsel mercekleme ismi verilen bir fenomenin sonucu. Max Planck Astrofizik Enstit\u00fcs\u00fc\u2019nden astronom Conor O’Riordan, \u201cT\u00fcm g\u00fc\u00e7l\u00fc mercekler azd\u0131r ve bilimsel a\u00e7\u0131dan son derece k\u0131ymetlidir.
