Globular Cluster Messier 14

Object Description

The globular cluster Messier 14 was added to his list of nebulous celestial objects by Charles Messier just a few days after the discovery of M 9 and M 10 in June 1764.

M 14 belongs to those globular clusters that do not have a sharply defined central compression. The brightness curve extends gently over the entire pane and drops continuously at the outer edges. The integrated spectral type is given as G0 and the distance as about 70'000 light years, but this value still needs a large correction due to the dusty region of the Milky Way, which is in the line of sight to M14. The cluster shows a radial speed of 130 km/s in our direction [4]
