Barred Galaxy (NGC 253) in Multiple Wavelengths

NGC 253, characterized by its vigorous star formation and spiral dust lanes, reveals its underlying structure in multiple wavelengths.

In NGC 253, the visible-light view is complicated by the viewing angle, dark dust clouds, and scatterings of massive stars. Switching to the near-infrared lets us see the full population of stars more clearly, revealing a bar running through the center of the galaxy. Including mid-infrared also brings out the dust lanes clearly, and even highlights the areas where stars are forming vigorously, particularly in the galaxy's center.



Optical: Dust and bright stars confuse the view in visible light.

Near-Infrared: Dust lanes along the spiral arms glow in the mid-infrared.

Mid-Infrared: The base population of stars reveal the spiral arms and central bar.
