Arp Bot 🤖Hubble Space Telescope image of Arp 147, also known as IC 298.
The clumpy, blue ring in the galaxy on the right likely formed when the companion galaxy to the left crashed through its center. This sent a pressure wave outward, like a ripple in a pond, compressing the right galaxy's gas and triggering the formation of new stars.
