A galaxy typically has several star clusters.
Stars, star clusters, distant galaxies, galaxy clusters, nebulae, ...
global clusters, open clusters and star clusters. (:
Any major galaxy has LOTS of star clusters, including globular clusters, if that's what you mean.

Nebulae or star clusters within the Milky Way Galaxy.
They are located only in the ARMS of galaxies, not outside.
The question contains the answer 100,000. "if each of these star clusters contains 100,000 stars, how many stars exist in these clusters" If you mean the total number, are you seriously saying you don't know how to multiply 100,000 by 158?
Such groups exist at different levels:* Star clusters * Galaxies * Galaxy clusters * Superclusters
There was a supernova this week (written on Jan 28 2014). The star is outside our Galaxy, but it's visible with a small telescope.
Yes. The constellations we see, in fact all star visible from earth make up just a small part of one galaxy. A constellation may have a handful of stars while a Galaxy has billions if not hundreds of billions.
