Description

The Whirlpool Galaxy

Description:

Shot during the new moon of May, M51 resides in the constellation Canes Venatici. The term "Galactic Interaction" seems a bit subtle for the power and energy displayed for all to see. It's two prominent galaxies swirl around each other as two predators circle before entanglement. Billions of years from now, our own Galaxy will suffer the same confrontation with Andromeda.

from wiki:

The Whirlpool Galaxy, also known as Messier 51a, M51a, or 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.
