M77 - Barred Spiral Galaxy
M77 is a barred spiral galaxy located in the constellation Cetus. It was discovered by Pierre Méchain in 1780 and later cataloged by Charles Messier. M77 is one of the largest galaxies in the Messier catalog and is known for its active galactic nucleus.
M77 spans about 170,000 light-years across and contains a massive population of stars, gas, and dust. The galaxy is approximately 47 million light-years away from Earth and has an apparent magnitude of 8.9, making it visible with a small telescope.
