Two wispy, gaseous clouds occupy the corners of this image, HH 1 in the upper right, and HH 2 in the lower left. Both are light blue and surrounded by dimmer multi-colored clouds, while the background is dark black due to dense gas. A very bright orange star lies just to the lower left of HH 1, and beyond that star is a narrow jet, emerging from the dark center of the field. Image credit: NASA / ESA / Hubble / B. Reipurth / B.

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.
