1、A typical globular cluster has about 1 million stars.
2、Below and to Antares' right is the globular cluster Messier 4.
3、NANCY GRACE ROMAN: "I think the image that to me was most striking was the center of a globular cluster."
4、The image shows both old stars and youngstars, a galactic globular cluster and emission from dust in our owngalaxy
5、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.
6、A66 is a red star located at the lowest end of the red giant branch (near the top of the sub-giant branch) of the globular cluster M4.
7、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.
8、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.
9、Caption:: Located in the constellation Herculues, M13 is the largest and brightest globular cluster in the northern sky, third in the whole sky, after the Omega Centaurus and47 Tucanae.
10、Absolute proper motions of about 532 stars in the field of the globular cluster M10 (NGC 6254) were determined with respect to Hipparcos and ACT reference stars. In addition to photographic plates of Bonn and Shanghai also wide field CCD observations as second epoch plates were used.
11、Different plants depict stars, globular clusters, and even nebulas.
12、M13 is one of nearly 150 known globular clusters surrounding our Milky Way galaxy.
13、There is no absolutely sharp cutoff distinguishing galaxies from globular clusters.
14、Recently astronomers have discovered these intermediateage globular clusters in several elliptical galaxies.
15、Smaller groups of stars called globular clusters often surround spiral galaxies.
16、Astronomers have scanned the complete sky with various telescopes and detected pulsars in the Milky Way and nearby globular clusters.
17、whether it hosts a good variety of different types of star, which excludes globular clusters which contain only similar stars;
18、At more than ten billion years old, globular clusters are some of the oldest objects in the universe.
19、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.
20、However, they could arise in globular clusters, where massive objects quickly settle to the center like heavier molecules at the base of Earth's atmosphere.
21、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.
22、Omega Cen is the largest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy.
23、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.
24、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).
