Hickson 44 in Leo
Canadian astronomer Paul Hickson identified 100 compact #galaxy groups, one being Hickson 44 in Leo, 100 million light-years away. This group includes spirals NGC 3190 and NGC 3187, elliptical NGC 3193, and spiral NGC 3185. Their interactions hint at future mergers, a common aspect of galactic evolution.
