Spiral arms get fractal complications now
Quote Tweet
In visible and ultraviolet light, @NASAHubble (left) shows dark regions of dust that separate the spiral arms. Webb (right) is able to peer through that dust in mid-infrared light, instead seeing patterns of gas that echo the arms’ shape.

Side-by-side comparison of galaxy IC 5332 as seen by the Hubble and Webb telescopes. It pieces together the left half of Hubble’s image and the right half of Webb’s image, with a white line separating the two. Each side is labeled. Hubble’s half shows glowing blue stars making up the spiral arms of the galaxy, with dark brown regions of dust in between the arms. Webb’s half resembles gray cobwebs, which are patterns of gas, in the shape of a spiral. Tiny blue dots are scattered throughout, as well as some larger, sparser red dots. The galactic core glows pale yellow on Hubble’s side and blue on Webb’s side.
