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).

These images span a range of different types of objects, including a cluster of galaxies (SMACS J0723.3-7327), a galaxy group (Stefan’s Quintet), a star-forming nebula (Carina Nebula), and a galaxy (Cartwheel Galaxy). In each image, the X-rays from Chandra show higher-energy processes than the infrared view from Webb. Additionally, infrared data from Spitzer is included in the Stephan’s Quintet composite.

The inner region of the Orion Nebula as seen by the NIRCam instrument on board the NASA/ESA/CSA James Webb Space Telescope. This is a composite image from several filters that represents emission from ionized gas, hydrocarbons, molecular gas, dust and scattered starlight. Most prominent is the Orion Bar, a wall of dense gas and dust that runs from the top left to the bottom right in this image, and that contains the bright star θ2 Orionis A. The scene is illuminated by a group of hot, young massive stars -- known as the Trapezium Cluster -- that is located just off the top right of the image. The strong and harsh ultraviolet radiation of the Trapezium cluster creates a hot, ionized environment in the upper right, and slowly erodes the Orion Bar away. Molecules and dust can survive longer in the shielded environment offered by the dense Bar, but the surge of stellar energy sculpts a region that displays an incredible richness of filaments, globules, young stars with disks and cavities.

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.
