Discovered by Charles Messier in 1764.

M14 is a slightly elliptically shaped stellar swarm, about 72 light years across and 29,000 light years away. It lacks a dense central condensation (Burnham), and contains a considerably large number of over 70 variables.

In 1938, a nove appeared in M14, which however was not discovered before 1964, when Amelia Wehlau of the University of Western Ontario surveyed a collection of photographic plates taken by Helen Sawyer Hogg between 1932 and 1963. This nova was visible on 8 plates, taken between June 21-28, 1938, as a 16th mag star. It was the second known nova in a globular cluster after that of 1860 in M80, T Scorpii, and the first one ever photographed.

Globular cluster M14 was the first CCD image taken, according to TheSky advertising.
