UGC 9240 (or DDO 190) is a dwarf irregular galaxy in the vicinity of the Milky Way as it is relatively small and lacks clear structure. It is 9.10 megalight-years (2.79 Mpc) away from us and lies out of the Local Group determined by the tip of the red giant branch method. The outskirts of the galaxy are harbouring older (reddish) stars while the centre is crowded with younger (bluish) stars. Heated gas is observed at several places. DDO 190 still experiences some active star formation.
