Mark Morel captured this stellar shot of Messier 13 in Hercules with his SVX130T. This globular cluster of stars is approximately 25,000 light-years away from Earth and is one of over a hundred that orbit the center of the Milky Way. Stars in this cluster are so tightly packed that they sometimes collide, producing new stars as a result. These newly formed stars are known as “blue stragglers,” because they are more luminous and bluer than other stars.
