APOD: Portrait of NGC 3628 (2022 Apr 29)

Image Portrait of NGC 3628

Explanation: Sharp telescopic views of NGC 3628 show a puffy galactic disk divided by dark dust lanes. Of course, this portrait of the magnificent, edge-on spiral galaxy puts some astronomers in mind of its popular moniker, the Hamburger Galaxy. It also reveals a small galaxy nearby (below), likely a satellite of NGC 3628, and a very faint but extensive tidal tail. The drawn out tail stretches for about 300,000 light-years, even beyond the upper left edge of the frame. NGC 3628 shares its neighborhood in the local universe with two other large spirals M65 and M66 in a grouping otherwise known as the Leo Triplet. Gravitational interactions with its cosmic neighbors are likely responsible for creating the tidal tail, as well as the extended flare and warp of this spiral's disk. The tantalizing island universe itself is about 100,000 light-years across and 35 million light-years away in the northern springtime constellation Leo.

Hamburger in the sky! 🍔 Or maybe it's really a hot dog? 🌭

Very nice shot by Wilhelm Michael Kasakow and Olaf Guillaume.

I also really like the APOD from 2011 March 16, because you can still see the star-forming regions there in pink and red.

But what I don't understand is the statement

Where can this galaxy be seen?

For me the satellite galaxy wasn't seen; but you could se the stream
of stars in the video! :shock:

Nice view of the triplet! 8-)

Yeah, pretty darn difficult to discern either the small satellite galaxy below or the extensive tidal tail above. But luckily, the link-to video shows both MUCH more clearly (though it's all about the Quasars and not the Hamburger Galaxy per say):
