The Whirlpool Galaxy

The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way, but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.

As well as all your other galaxy and hubble pics. DA is about own creations. Next infraction will be reported to DA and to the original copyright holders. I would recommend removing them. And rereading the posting policies. Fines can get very expensive,

You can technically repost anything online with proper credit. They gave specific proper credit. Thus are alright. And they aren't making money off it. Thus, they are completely within the law.
