M105 | NGC 3379 | Elliptical Galaxy | Leo | 6,300 Light Years Away
Messier 105 is a lenticular galaxy situated in the constellation Leo. Discovered by Pierre Méchain in 1781 and later included in Charles Messier’s catalog, it is part of the Leo I Group of galaxies. Located approximately 32 million light-years away from Earth, Messier 105 is characterized by its smooth, featureless appearance, typical of lenticular galaxies.
The central region of Messier 105 is dominated by an elliptical structure, and it lacks the prominent spiral arms seen in spiral galaxies. Lenticular galaxies like Messier 105 are often considered transitional between elliptical and spiral galaxies, showcasing features of both types. Observations of Messier 105 contribute to the study of galactic morphology and the classification of different galaxy types based on their structural characteristics.
Messier 105 is often studied in conjunction with the other galaxies in the Leo I Group, providing insights into the dynamics and interactions within this galactic neighborhood. While lenticular galaxies may not exhibit the same level of ongoing star formation as spirals, their study helps astronomers understand the diverse paths of galactic evolution. Messier 105, with its position in the Leo I Group, adds to the broader narrative of cosmic structures and their roles in shaping the vast cosmic tapestry.
