M4

What may be the closest globular cluster to Earth appears in the south on summer nights, but you need binoculars to see it. M4 contains several hundred thousand stars. It is probably about 6,000 light years away. It is visible through binoculars to the right of the orange star Antares, which is low in the south as darkness falls.
