Fig7_14 Globular star cluster NGC6934

Fig. 7.14 . Several hundred thousand stars swarm around the center of the globular star cluster NGC 6934, which lies at a distance of about 50,000 light-years from Earth. These ancient stars are estimated to be about 10 billion years old. This sharp image, obtained from the Hubble Space Telescope, is about 3.5 minutes of arc and 50 light-years across.
