1. Who discovered NGC 4125?1785
2. What is the morphological type?Lenticular galaxy (S0)
3. What is the host cluster?Coma Cluster (Abell 1656)
4. What type of galaxy is NGC 4125?NGC 4125 is a lenticular galaxy, which means it has a big central bulge and a flat disc but no spiral arms. It is a transition type between spiral and elliptical galaxies.
5. Why doesn't NGC 4125 have many new stars?The galaxy’s stars are mostly old and red, and it has very little gas left to form new stars. This means it stopped making new stars billions of years ago.

Lenticular Galaxy (S0): A galaxy type with a central bulge and a disc, but lacking prominent spiral arms and significant gas.
Coma Cluster: A large, dense cluster of thousands of galaxies, serving as a key laboratory for studying galaxy interactions.
Ram-Pressure Stripping: The process where gas is removed from a galaxy as it moves through the hot gas in a galaxy cluster.
Stellar Population: A group of stars within a galaxy that formed at roughly the same time and with similar chemical compositions.
