Normal Stars & Star Clusters
In this section we focus on the youth and middle age of stars. Chandra and other X-ray telescopes focus on the high-energy action of this drama - the turbulent, multimillion degree outer atmospheres and gale-force outflows of gas from hot, luminous stars.
The stellar end game inevitably produces dense, collapsed stars - white dwarf, neutron stars, and black holes - where gravity is strong and conditions are often violent. X-ray telescopes are especially suited to explore these objects, so separate sections are devoted to them.
Clusters of young stars are irregularly shaped and are called open clusters, to distinguish them from globular clusters, spherically shaped clusters of very old stars.
