Windhorst et al. traced light that was emitted by the bright elliptical galaxy VV 191a (left) through the spiral galaxy VV 191b (right). As a result, they were able to identify the effects of interstellar dust in the spiral galaxy. Webb’s near-infrared data also shows us the galaxy’s longer, extremely dusty spiral arms in far more detail, giving them an appearance of overlapping with the central bulge of the bright white elliptical galaxy, though the pair are not interacting. In this image, green, yellow, and red were assigned to Webb’s near-infrared data taken in 0.9, 1.5, and 3.56 microns (F090W, F150W, and F356W respectively). Blue was assigned to two Hubble filters, ultraviolet data taken in 0.34 microns (F336W) and visible light in 0.61 microns (F606W).

This Hubble image shows the galaxy pair Arp-Madore 608-333. The color image is composed of near-infrared and optical observations from Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Messier 74, a grand design spiral galaxy located 32 million light-years away in the constellation of Pisces, shines at its brightest in this combined optical/mid-infrared image, featuring Webb and Hubble data. The red colors mark dust threaded through the arms of the galaxy, lighter oranges being areas of hotter dust. The young stars throughout the arms and the nuclear core are picked out in blue. Heavier, older stars towards the galaxy’s center are shown in cyan and green, projecting a spooky glow from the core of Messier 74. Bubbles of star formation are also visible in pink across the arms.
