Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores of smaller galaxies the Milky Way has captured over the ages? The answer might be “both.” We also know they are ancient, as old as the galaxy itself.
M92 is one of the brightest globular clusters, located within the constellation Hercules. Its more photogenic neighbor M13 gets photographed more, but I decided to give M92 some love. It’s pretty too.
