Please answer on clusters!?

Question

Why does open clusters arre mainly seen in arms of our milky way(galaxy), while the more older stars containing -Globular clusters are seen in the middle of the galaxy.

Please explain the both
thans for the time

Answer 1

open clusters

(astronomy) One of the groupings of stars that are concentrated along the central plane of the Milky Way; most have an asymmetrical appearance and are loosely assembled, and the stars are concentrated in their central region; they may contain from a dozen to many hundreds of stars. Also known as galactic cluster.

globular cluster

Any large group of old, Population II stars closely packed in a symmetrical, somewhat spherical form. About 150 have been identified in the Milky Way Galaxy. Most are distributed in a spherical volume above and below the Galaxy's disk (see galactic halo). Globular clusters contain many more stars (10,000–1,000,000) than open clusters do and can be several hundred light-years in diameter. Because they are so distant from the solar system, most are not visible to the unaided eye. Omega Centauri and a few others can be seen without a telescope as hazy patches of light.

Answer 2

Of course we know the answer to that. Open clusters are new clusters of stars (just a few stars, usually), which form in the gas-rich spiral arms. Globular clusters are old clusters of stars (millions of stars) which orbit around the galaxy - they are strongly graviationally bound, unlike the loosely bound open clusters.

Answer 3

Good question, and one that there has been a lot of work done on . But, so far as I know, there are a lot of theories and no real proof of why cosmological evolution works the way it does.
