Why globular clusters are generally used to study the initial chemical composition of galaxies?
Because all their constituent stars are at the same distance, globular clusters are also invaluable as testbeds for understanding stellar structure and evolution, and for serving as the basis for models of stellar populations.
What is the true distance to NGC 6822?
approximately 1.6 million light-years away
NGC 6822 (also known as Barnard’s Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius.
How far away is NGC 6822?
1.631 million light yearsNGC 6822 / Distance to Earth
Beyond the rich starfields in the constellation Sagittarius, NGC 6822 is a mere 1.5 million light-years away, a member of our Local Group of galaxies. A dwarf irregular galaxy similar to the Small Magellanic Cloud, NGC 6822 is about 7,000 light-years across.

How far are galaxies apart?
about one million light years
The average distance between galaxies is about one million light years. There are roughly 100 billion galaxies in the observable universe. Another, often-used unit of distance is the parsec. One parsec is approximately 3.26 light-years.
How many miles away is the closest star?
The closest star, Proxima Centauri, is 4.24 light-years away. A light-year is 9.44 trillion km, or 5.88 trillion miles. That is an incredibly large distance. Walking to Proxima Centauri would take 215 million years.
Why don t stars collide when galaxies collide?
In some ways, when a galactic merger takes place, the two galaxies are like ghosts; they simply pass through each other. That’s because stars inside galaxies are separated by such great distances. Thus the stars themselves typically don’t collide when galaxies merge.
What happens to stars when galaxies collide?
When two galaxies of the same size are merging, many new stars form, making the merging galaxies brighter. However, if these galaxies merge too quickly, many of the newly formed stars are likely to die shortly after their formation.
