To celebrate #NASAWebb’s second year of science, let’s look back at one of its first images, the Cartwheel Galaxy. This near- and mid-infrared image shows the areas where stars develop after a high-speed collision about 400 million years ago: bit.ly/3WfJYW2 🔭 🧪
Image of a large galaxy on the right, with two smaller companion galaxies to the left. The large galaxy is ring-shaped, with an oval outer ring, and a small, off-center oval inner ring. The rings and space between are lit with blue and crimson red plumes and dots. The blue areas are pockets of young stars and hydrocarbon dust. The red areas are energized silica dust. The red dust trails from the outer ring toward the inner ring and bright white core. The companion galaxies to the left, one above the other, are much smaller than the main galaxy, and about the same size as each other. The galaxy above has similar coloring and many of the same features as the large ring galaxy, but more of a disturbed s-shape, with no distinct rings. The galaxy below is white with a slight blueish to pinking tinge. It has a diffuse spiral shape with a white core similar to that of the ring galaxy, but with a smoother texture.
