Extragalactic planet This suspected planet is the first announced in the Andromeda Galaxy. A population of unbound planets between stars, with masses ranging from Lunar to Jovian masses, have been indirectly detected, for the first time, by astrophysicists from the University of Oklahoma, in the lensing galaxy that lenses quasar RX J1131-1231 by microlensing. Extragalactic planet An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet, or rogue planet, located outside of the Milky Way galaxy. Due to the huge distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets
First Cambridge Catalogue of Radio Sources axis is not exactly East-West. The survey found radio sources in close proximity to four of the five major extragalactic nebulae, namely M31, M33, M101 and M51, corresponding to sources 00.01, 01.01, 14.01 and 13.01 respectively. Only M81 had no observed radio source. The isotropy of the sources lead the team to conclude that radio stars were either local phenomena, or extragalactic. First Cambridge Catalogue of Radio Sources The First Cambridge Catalogue of Radio Sources (1C) refers to the catalogue listed in the article "Ryle M, Smith F G & Elsmore B (1950) MNRAS vol 110 pp508-523 "A Preliminary Survey
