IC 5332, also known as PGC 71775 is an intermediate spiral galaxy about 30 million light-years away in the constellation Sculptor. IC 5332 is a delicate spiral galaxy that is unusually faint and beautifully symmetrical. As viewed from earth it is nearly face on. It has a very small central bulge and open spiral arms accounting for its classification (SABc). The galaxy lies in the direction of the celestial south pole.
I wanted to highlight the JWST dust lanes more clearly, so I decided to stick to truer color and make the observations red. The result was something a lot more striking, which I like! It’s awesome to see how the dust lane spiral angle and the stellar spiral angle don’t match – not sure why this is.
