Open Clusters
they collect particals and form stars close together
They are not related. But they are about the same subject, Stars. Astrophysics is the study of the physics of the stars in the universe. The Zodiac signs are the names given to the groups of stars called constellations.
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.
the space from the planet the stars or clusters
Several regions of the HR diagram have been given names, although stars can occupy any portion. The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
The hottest stars. Generally, globular clusters contain mainly old stars, population II stars
galaxies
Constellations are much, much, much larger than our solar system. They are actually clusters of stars and galaxies that appear to form shapes which over the centuries have been given names by us.
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?

stars
Globular clusters are small groups of stars, while the milky way is a large galaxy containing hundreds of billions of stars, along with some of these clusters.
