Despite popular opinion, dogs can actually see some color. They have 2 photoreceptors, blue and yellow. This means they are unable to see red and green, so finding a red ball on green grass is a very difficult task for a dog.

Pinwheel Galaxy (Wikipedia) The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on, unbarred, and counterclockwise spiral galaxy located 21 million light-years (6.4 megaparsecs) from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
