 Here's a Hubble view of the Cartwheel galaxy, a ring galaxy around 500 million light-years away. Its striking ring-like feature is a direct result of a smaller galaxy, probably one of the two objects on the left of the ring, that passed through the core of this galaxy. Presumably, the Cartwheel galaxy was a normal spiral galaxy like our Milky Way before the collision. Here's Webb's combined image from both the near-infrared and mid-infrared cameras. The galaxy has two rings, a bright inner ring and a surrounding colorful outer ring. These two rings have been expanding outwards from the center of the collision for around 440 million years. The bright core contains a tremendous amount of hot dust with the brightest containing gigantic young star clusters. The outer ring is dominated by star formation and supernovas. As this ring expands, it plows into surrounding gas and triggers additional star formation. The galaxy is 150,000 light-years across. Our entire Milky Way galaxy could fit inside. Here's a look at the galaxy from just the mid-infrared camera. The pre-collision spiral structure is beginning to reemerge, as seen in the faint arms or spokes between the outer ring and the inner ring.
