Aug They usually contain several thousands of stars if not tens of thousands of stars, and are very densely packed. The general working theory is that open clusters are the remnants of bursts of star formation, while globular clusters are the remains of the cores of small galaxies eaten by the Milky Way. How are globular clusters different from galaxies and. Sep Both are types of star clusters , but the major differences come down to the age of the stars found within them, where they can be found in a . What is the difference between a globular cluster and an open cluster?

Jun Three main differences: shape, star age, and location . There are two types of star clusters. Open (or galactic) clusters are sparsely populate fairly young groups of. In contrast, globular clusters are very tightly bound by gravity.

Open clusters are found only in spiral and irregular galaxies, in which active star formation is . Nov Take a look at the different star clusters in our night sky. Many of the closer ones, including those presented here,. Though several globular clusters , . When a cluster is young, the brightest members are O, B and A stars. Young clusters in our Galaxy are called open clusters due to their loose appearance. Feb We discuss some of the key open questions regarding the formation and evolution of globular clusters (GCs) during galaxy formation and.

Jan Omega Centauri is facing an identity crisis, as an online poll is set up to decide how to distinguish between dwarf galaxies and star clusters. Aug Click the icon to view Star Clusters of the Messier Catalog. Thus, globular clusters are believed to be very old and formed from an earlier . For example, the Pleiades and the Hyades clusters are open . And when you have motion, you can defeat gravity for a time. Each star is in orbit around the center of the globular cluster , and the motion of the star in a . Jan Old globular clusters keep imprints of the physical conditions of their.

They contain hundreds of thousands, and sometimes millions, of stars. The initial mass distribution functions for young and old globular clusters , open clusters and associations, and interstellar clouds are all power laws with a slope. May Matt Taylor and his team have now made the most detailed studies so far of a sample of 1globular star clusters around Centaurus A using . E NCYCLOPEDIA OF ASTRONOMY AND ASTROPHYSICS.

Even a small telescope shows obvious local concentrations of stars scattered around . Some, such as the Sun, are single (field star ), but others are members of pairs or form multiple- star systems. Still others form clusters of various types, and size. Open clusters : few - 1M⊙ few Myr - few Gyr.

Introduction to stellar clusters. What key problems remain in our present knowledge of globular clusters ? Only a few nearby OPEN clusters have been studied in this way, and even here the . Globular clusters (GCs):.
