Messier of the Month – M12 (Gumball Globular)

M12, also known as the Gumball Globular, is a magnitude 7.6 globular cluster in the constellation Ophiuchus. It is about 15,700 light years distant, contains about 200,000 stars, and has an estimated age of 12 to 13 billion years. M12 appears as a fuzzy patch through binoculars and smaller telescopes. An 8-inch scope will resolve the brightest stars, while a 10-inch scope will reveal the core.
