Allan Sandage's work focused on globular clusters;
Most globular clusters orbiting the Milky Way are estimated to be over 10 billion years old;
The researchers also identified at least eight globular clusters that were brought into the Milky Way by the Sausage galaxy.
Many globular clusters have ages in excess of 12 billion years, with some even exceeding 13 billion years.
This is usefulwhen we have large populations of stars, like globular clusters, but is more difficult for individual stars.
Even the globular clusters are strange: they are twice as large as typical groups of stars.
He has shown that, if there are too many black holes, these globular clusters would heat up, puff up, and die out very quickly.
Even the globular clusters are strange: they are twice as large as typical groups of stars.
For more than two hundred years after its discovery, Messier 54 was thought tobe similar to the other Milky Way globular clusters.
Even the globular clusters are oddballs: they are twice as large as typical stellar groupings seen in other galaxies.
Some theorists believe that thegalactic bulge is formed by a merger of globular clusters, so the new stars would support that idea.
Even its globular clusters are oddballs-- They are twice as large as typical stellar groupings seen in other galaxies.
M2 has a diameter of about 175 light-years, contains about 150,000 stars,and is one of the richer and more compact globular clusters.
But globular clusters, like M4, are made primarily of hydrogen and helium, and are practically a dust-free environment.
Being only about 200 light-years across and mostly made up of old stars,these galaxies resemble brighter and larger versions of globular clusters.
Like many other globular clusters, Messier described it as"Nebula without stars", as did Bode 10 years later;
This animation offers a blink comparison of the locations of red stars andblue stars in the globular clusters of the NGC 1277 and NGC 1278 galaxies.
Some stars in globular clusters appear to be as old as the universe itself(by entirely different measurement and analysis methods)!
M 72 isalso one of the more remote of Messier's globular clusters: at about 53.000 light years, it lies a considerable distance beyond the Galactic Center.
Globular clusters are typically located in the outer regions(the halos) of galaxies, and our Milky Way galaxy has about two hundred of them.
While initial observations of the velocity dispersion, via globular clusters, indicated that NGC 1052-DF2 was one of them, newer observations throw that conclusion into doubt.
Globular clusters are mainly composed of tens of thousands of very ancient stars, but they also contain some stars that look suspiciously young.
Originally we observed these globular clusters to measure their central velocity dispersions"- that is, the random motions of stars within a cluster. .
Globular clusters are among the most fascinating celestial phenomena in the galaxy, packing a hideous amount of stars into a relatively tiny region of space.
But globular clusters are not static relics from the past-- some curious stellar activities are still going on in these dense star cities.
Globular clusters consist of densely packed stars in spherical collections, dating from early years of the universe, typically with ages of 12 to 13 billion years.
Globular clusters, also simply known as globular, are star clusters concentrating approximately ten thousand to one million very old stars.
