Globular clusters in the Galaxy are all old objects, with ages of about 1010 years. The LMC is quite different: its globular clusters have ages anywhere between about 5 × 106 years and 1010 years. It is important to find out why globular clusters can form now in the LMC but not in the Galaxy; the galactic globulars play a major role in our picture of the early history of the Galaxy, and it is obviously desirable that we should understand the conditions under which these clusters can form.
