Our next entry in the 19 days of #PHANGS series is the spiral galaxy NCG 1566, seen here in images from #Hubble and #JWST.

NCG 1566 is a grand-design spiral galaxy that has two arms that wind around its core. The apparent movement of its twirling arms gives the galaxy its nickname, the Spanish Dancer.

NCG 1566 is about 58 million light years (18 Mpc) away, one of 26 galaxies in the Dorado galaxy group.

Hubble’s image of NGC 1566 shows a densely populated face-on spiral galaxy anchored by its central region, consisting of a core and small bar structure, which has a light yellow haze of stars that takes up about a quarter of the view. The core is brightest at the center, washing out some light from other objects. Two prominent, delicate spiral arms start near the center and extend to the edges, rotating counterclockwise. There is brown dust beginning at the center, but as the arms extend outward, brown dust lanes alternate with diffuse lines of bright pink stars. The outermost areas of the spiral arms have many purple and blue stars. The brightest areas of the arms are two large pink arcs that start at the central region and stretch up to the top and bottom. Toward the outer areas, there are some orange and red points of light spread throughout, likely galaxies, and several slightly larger foreground stars with four diffraction spikes. Triangles at the top right, bottom right, and bottom left corners are black, where there is no data.
Webb’s image of the galaxy NGC 1566 shows a densely populated face-on spiral galaxy anchored by its slightly oval central region, consisting of a core and small bar structure, which has a light blue haze of stars that covers about a quarter of the view. Two prominent spiny spiral arms made of stars, gas, and dust also start at the center, within the blue haze, and extend to the edges, rotating counterclockwise. The spiral arms of the galaxy are largely orange, ranging from dark to bright orange. The brightest areas of the arms are two large arcs that start at the central region and stretch up to the top and bottom. Scattered across the packed scene are innumerable bright blue pinpoints of light, which are stars spread throughout the galaxy. In areas where there is less orange, it is darker, and some dark regions look more circular. There are bright pink patches of light toward the outer regions of the spiral arms.
