What is the relationship between globular clusters and the milky way

The Milky Way is part of the Local Group Cluster , part of the Virgo Super Cluster. What is a globular cluster ? A globular cluster is a dense group of old stars within a galaxy that have formed a. Most globular clusters are found in the large spherical halo of a galaxy. Galaxies contain billions of stars, including star clusters. Star clusters are groups of stars that are gravitationally attracted.

A galaxy is, by definition, any large collection of stars that can be recognized as a distinct physical entity. How are you going to learn any of this if you have someone else tell you the ? Star Clusters and the Shape of the Milky Way. So the globular clusters (which contain very old stars) reveal a spherical component of the Milky Way , while the open clusters and other young stars and star-forming regions reveal a disk-shaped component of the Milky Way. Harlow Shapley assumed , very reasonably, that the center of the globular clusters was the center of the Milky Way.

Top: The globular cluster M8 imaged by the Hubble Space Telescope. BottoThe Large Magellanic Clou an irregular dwarf galaxy that is a companion to our Milky Way.

Because globular clusters are located in the halo of the Milky Way and not in the disk, they are not impacted the initial effects of additional mass as their distances from the galactic center increase as disk stars do. Forbes, Pavel Kroupa, Manuel Metz, and Lee Spitler Our Milky Way galaxy is host to a number of companions. We tend to think of globular clusters as bound to our Milky Way galaxy or other galaxies. So it’s surprising to hear of globular clusters scattered between galaxies in the Coma galaxy cluster.

As their name suggests, globular clusters are globule-shaped balls of hundreds of thousands of stars all crammed into an area a few hundred light years across. They live in the halo of our galaxy and orbit the galactic centre. The mass of a galaxy’s super massive black hole (SMBH) is known to have a strong relationship between many features of their host galaxies. It has identified to follow the range of velocities of stars in the galaxy, the mass and luminosity of the bulge of spiral galaxies,. Though several globular clusters , such as Omega Centauri in the constellation Centaurus and Messier (M13) in the constellation Hercules , are visible to the unaided eye as hazy patches of light, attention was paid to them only after the invention of the telescope.

Roughly spherical in shape, they contain hundreds of thousands, and sometimes millions, of stars. Globular Clusters : Dense Groups of Stars. Studying them helps astronomers estimate the age of the universe or figure out where the center of a galaxy lies. There are about 1known globular clusters in the Milky Way galaxy,.

Our galaxy has about 1globular clusters , some of which may have been captured from small galaxies disrupted by the Milky Way , as seems to be the case for the globular cluster M79. Some galaxies are much richer in globulars: the giant elliptical galaxy Mcontains over a thousand. Open clusters populate about the same regions of the Milky Way and other galaxies as star-forming nebulae, notably spiral arms in disk galaxies, and irregular galaxies, and are thus found along the band of the Milky Way in the sky. In order to conduct his research, Shapley looked at globular clusters around the Milky Way. Shapley was able to use the Cepheid variables of nearby globular clusters to calculate the distances to those clusters.

Some of the more distant clusters had no visible Cepheid variables. Explain why we see the Milky Way as a faint band of light stretching across the sky. Explain where in a spiral galaxy you would expect to find globular clusters , molecular clouds, and atomic hydrogen. Abstract: We report on the kinematics of Milky Way (MW) globular clusters (GCs) based on updated space velocities for nearly the entire GC population. We found that a 3D space with the semi-major axis, the eccentricity and the inclination of the orbit with respect to the MW plane as its axes is helpful in order to dig into the formation of the GC system.

The mean optical and optical-near-infrared colors of the clusters are consistent with those of the Milky Way.
