: Much younger and more distant than any other globular star cluster in the Milky Way, the Crater cluster was discovered two years ago by researchers using the Hubble Space Telescope
. At just 7.5 billion years old, the cluster is thought to have been plucked
from the Small Magellanic Cloud (SMC), a nearby galaxy some 200 000 light-years from Earth, because the SMC’s other globular clusters are of a similar age. Further evidence is the cluster’s location, speed, and chemical composition, which are similar to those of other clusters in the SMC.
