The “Whirlpool” galaxy is seen rotating in a counter clockwise direction. Note the smaller, yellow galaxy on the left. It has passed quite close to the larger galaxy. This near encounter has resulted in the “plumes” of material coming out of it, and a long arm has been drawn out of the “Whirlpool” towards it.
