    60 millisecond pulsars in the globular cluster 47 Tucanae: that is what the FERMI observatories concluded when for the first time they showed gamma-ray coming from a globular cluster. Millisecond pulsars are particularly abundant in the globular clusters but for now, radio or X-ray observations could only reveal 23. So for the first time gamma observations allowed scientists to conduct a better census of millisecond pulsars in the globular clusters and thus to better understand the evolution of those mini-galaxies of early ages of the universe. This result was announced in the August 14th, 2009 issue of Science.
