Nearby star-forming FEAST galaxies (IMAGE)
Caption
(picture 2, color composites of the four galaxies)
A collage featuring four images of spiral galaxies observed by Webb. Blue colours, especially in the centre of the galaxies, are near-infrared light that show the location of bright stars. Orange and yellow show ionised gas and red colours come from complex molecules and dust grains; these are longer mid-infrared wavelengths. They trace out the spiral arms of each galaxy as a network of filaments with cavities in between.]
