This is a globular cluster, a sphere of tens of thousands of stars. Most of them are a whitish color, and more concentrated in the center of the sphere. As you move farther from the center, there are fewer stars.

C42 (NGC 7006)

NGC 7006 resides in the outskirts of the Milky Way. This roughly spherical region of our galaxy is made up of dark matter, gas and sparsely distributed stellar clusters. Like other remote globular clusters, NGC 7006 provides important clues that help astronomers to understand how stars formed and assembled in the halo. The cluster has a very eccentric orbit, indicating that it may have formed independently in a small galaxy outside our own that was then captured by the Milky Way.
