Different plants depict stars, gloBular clusters, and even nebulas.

A study of many globular clusters gives another important bit of information.

We also describe the basic principle of White Dwarf cosmochronology and its application in defining the age of the Galactic disk, globular clusters, open clusters and Galactic halo.

The smallest looser 'open clusters' have only a few stellar members, whilst the largest tightly bound' globular clusters' have as many as several million stars.

But even this misses out various characteristics that astronomers think are important, such as dominating the local environment, in the way the Milky way dominates the globular clusters nearby.

NANCY GRACE ROMAN: "I think the image that to me was most striking was the center of a globular cluster."

Another interesting aspect to this object is that it is found within a globular cluster, a very old, very tight grouping of stars.

When you've got two million stars to gawk at, not much else needs to be said, except this shows only one-fifth of the stars in this globular cluster.

For this purpose the study of globular clusters is most instructive.

If such galaxies formed by the merger of spirals, they should contain old globular clusters( those originally associated with the spirals) as well as younger ones( created during the merger).

Evidence from NASA's Chandra X-ray Observatory and the Magellan telescopes suggest a star was torn apart by an intermediate-mass black hole in a globular cluster.

Omega Cen is the largest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy.

We could have hundreds of stars, like a globular cluster, and they could collide with each other, they could explode, they could break apart all those forces are internal, they don't count.

A typical globular cluster has about 1 million stars.

The spectrum reveals emission from oxygen and nitrogen but no hydrogen, a rare set of signals from within globular clusters.
