Part 11/15:
This pair, UGC 1810 (the larger) and UGC 1813 (the smaller), appear as a beautifully structured “rose” due to gravitational interaction. Located around 300 million light-years away, their distorted shapes result from a smaller galaxy passing through the larger one, causing stellar stretching and triggering intense star formation. Embedded within the arm of UGC 1810 is a tiny spiral galaxy—a cosmic “galaxy within a galaxy.”
