M109 - Barred Spiral Galaxy
M109 is a barred spiral galaxy located in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and later cataloged by Charles Messier. M109 is known for its bright central bar and well-defined spiral arms.
M109 spans about 120,000 light-years across and contains a massive population of stars, gas, and dust. The galaxy is approximately 83 million light-years away from Earth and has an apparent magnitude of 9.8, making it visible with a small telescope.
