Leo Quartet/ Hickson 44
Hickson 44, also known as the Leo Quartet, is a compact galaxy group located approximately 80 million light-years away in the constellation Leo. This interacting system consists of four prominent galaxies: NGC 3190, NGC 3193, NGC 3187, and NGC 3185. NGC 3190, the brightest and most striking member, is a warped spiral galaxy with a prominent dust lane cutting across its disk. Nearby, NGC 3187 showcases distorted spiral arms, a sign of gravitational interactions, while the elliptical NGC 3193 remains relatively undisturbed. The smallest of the group, NGC 3185, exhibits a faint barred spiral structure.
These galaxies are in the process of a slow cosmic dance, their mutual gravitational forces shaping their evolution over millions of years. Hickson 44 is an excellent example of galaxy interactions influencing star formation, structural distortions, and potential future mergers. Deep exposures reveal faint tidal streams and extended halos, evidence of past interactions that continue to shape this fascinating galaxy group.
