Eyl\u00fcl 2026\u2019da f\u0131rlat\u0131lmas\u0131 planlanan Roman, Samanyolu\u2019nun “\u015fi\u015fkinlik” (bulge) olarak adland\u0131r\u0131lan merkez b\u00f6lgesini tarayarak binlerce yeni \u00f6tegezegen ve egzotik g\u00f6k cismi ke\u015ffedecek.

Roman Teleskobu’nun en b\u00fcy\u00fck yeteneklerinden biri, mikromerceklenme<\/strong> (microlensing) olaylar\u0131n\u0131 yakalamak olacak. Bu olay, uzaktaki bir y\u0131ld\u0131z\u0131n \u0131\u015f\u0131\u011f\u0131n\u0131n, \u00f6n\u00fcnden ge\u00e7en daha yak\u0131n bir nesnenin (bir y\u0131ld\u0131z, gezegen veya karadelik) k\u00fctle\u00e7ekimiyle b\u00fck\u00fcl\u00fcp parlamas\u0131 sonucu olu\u015fur.<\/p>\n\n\n\n

Hubble\u2019\u0131n 2025 y\u0131l\u0131nda ba\u015flatt\u0131\u011f\u0131 ve Roman\u2019\u0131n g\u00f6zlemleyece\u011fi alanlar\u0131 kapsayan devasa tarama, bu karma\u015fay\u0131 \u00f6nlemeyi ama\u00e7l\u0131yor.<\/p>\n\n\n\n

K\u00fctle \u00d6l\u00e7\u00fcm\u00fc:<\/strong> Mikromerceklenme normalde sadece bir k\u00fctle oran\u0131 verir. Ancak Hubble\u2019\u0131n verileri sayesinde, bilim insanlar\u0131 dolayl\u0131 tahminler yerine y\u0131ld\u0131zlar\u0131n ve y\u00f6r\u00fcngesindeki gezegenlerin ger\u00e7ek k\u00fctlelerini<\/strong> do\u011frudan \u00f6l\u00e7ebilecekler.<\/p>\n\n\n\n
