The spiral arms of NGC 3718 appear bent and elongated and are speckled with young blue star clusters. Pulled out dust lanes obscure the yellowish central regions. About 150,000 light-years to the right lies another large spiral galaxy, NGC 3729. The two likely interact gravitationally. While this pair of galaxies is about 52 million light-years away, Hickson Group 56 is at the top of the image above NGC 3718. Hickson Group 56 consists of five interacting galaxies and is more than 400 million light-years away. 

The picture was awarded "Amateur Astronomy Picture of the Day".
