YOUNG STAR CLUSTERS IN GALAXY NGC1275 . Jon Holtzman of the Lowell Observatory released high-resolution HST images of galaxy NGC1275 which show 50 bright objects believed to be massive, blue (and therefore very young, perhaps only hundreds of millions of years old) globular clusters. This is surprising because globular clusters in our own galaxy are among the oldest stars (typically 10 billion years old) in the Milky Way. Holtzman said that not only are these clusters blue, but almost precisely the same shade of blue, suggesting that the stars there formed at about the same time; this, Holtzman believes, may have been the result of two galaxies colliding or merging to form the present NGC1275.
