Leo Trio – M65 M66 NGC 3628

In Astrophotography by Matt Shetzer

The Leo Trio, includes 3 spiral galaxies, M65, M66, and NGC 3627 and gets its iconic name from being located in the Leo constellation.

Each of these galaxies are in a gravitational tug of war and titled at a different angles, making each of their appearances different.

Located 30 million lightyears from Earth, we are observing these three galaxies as they were in the past. They might not even be there now.
