NGC 3628, also known as the Hamburger Galaxy or less commonly Sarah's Galaxy, is a striking edge-on spiral galaxy located about 35 million light-years away in the constellation Leo. As part of the famous Leo Triplet along with M65 and M66, NGC 3628 offers a unique perspective, showcasing its warped and heavily dust-laden disk that appears like a cosmic sandwich.

Captured in RGB, this image highlights the galaxy’s prominent dark dust lane slicing across its glowing core. This dusty band obscures much of the galaxy’s starlight and gives NGC 3628 its distinctive “hamburger” shape. The outer edges of the galaxy also reveal faint tidal tails — evidence of past gravitational interactions with its neighbors in the Leo Triplet. These tidal tails extend for hundreds of thousands of light-years, stretching out as relics of galactic evolution.

Its faint ultraluminous X-ray source (ULX), detected near the galaxy’s outskirts. This intriguing object suggests the possible presence of either an intermediate-mass black hole or a binary system where material is being rapidly consumed, adding an additional layer of mystery to this well-known galactic neighbor.
