Gorgeous spiral galaxy NGC 3521 is a mere 35
million light-years away, toward the constellation Leo.
Relatively bright in planet Earth's sky, NGC 3521 is easily
visible in small telescopes but often overlooked by amateur
imagers in favor of other Leo spiral galaxies, like M66 and M65.
It's hard to overlook in this colorful cosmic portrait, though.
Spanning some 50,000 light-years the galaxy sports
characteristic patchy, irregular spiral arms laced with dust,
pink star forming regions, and clusters of young, blue stars.
Remarkably, this deep image also finds NGC 3521 embedded in
gigantic bubble-like shells. The shells are likely tidal debris,
streams of stars torn from satellite galaxies that have
undergone mergers with NGC 3521 in the distant past.
