Pulsar Jackpot Reveals Globular Cluster’s Inner Structure

Terzan 5 glboular cluster

The Milky Way is chock-full of star clusters. Some contain just a few tens-to-hundreds of young stars. Others, known as globular clusters, are among the oldest objects in the Universe and contain up to a million ancient stars. Some globular clusters are thought to be fragments of our galaxy, chiseled off when the Milky Way…
