M4: The Closest Known Globular Cluster (May 23 2000) Credit & Copyright: T2KA, KPNO 0.9-m Telescope, NOAO, AURA, NSF M4 is a globular cluster visible in dark skies about one degree west of the bright star Antares in the constellation Scorpius. M4 is perhaps the closest globular cluster at 7000 light years, meaning that we see M4 only as it was 7000 years ago, near the dawn of recorded human history. (...) M4 is one of the smallest and sparsest globular clusters known.
