The spiral galaxy M51 is almost 30 million light-years away, the image clearly shows clusters of young, hot stars that light up the spiral arms. Threaded through the arms are dark “dust lanes”, where sooty material left over from previous generations of stars has settled. More dust lanes can be seen in the bridge of luminous stars and gas that connects Messier 51 to its companion, the peculiar galaxy NGC 5195, in the upper part of the image.
