It’s part of a larger population of globulars that orbit the core of our Milky Way Galaxy. This cluster lies about 22,000 light-years away from Earth. Interestingly, scientists once sent a coded data message to this cluster, in the hopes that any civilizations there might receive it. It will arrive in just under 22,000 years. M92, the other cluster shown on the chart above is about 26,000 light-years away from our planet.
