Leo Triplet
Catalog: M65/M66/NGC 3628
The Leo Triplet is a striking group of three galaxies—M65, M66, and NGC 3628—seen together in the constellation Leo. Though they appear calm and graceful in the night sky, this system is shaped by gravity on a massive scale, with each galaxy influencing the others over millions of years. Their different forms make the grouping especially compelling: M65 and M66 show off bright spiral structure, while NGC 3628 appears edge-on, with a dark dust lane cutting dramatically across its length. Together, they create one of the most rewarding galaxy fields in the spring sky, offering a glimpse of multiple island universes sharing the same corner of space.
