What is a group of stars that form when a lot of gases and dust come together?
A group of stars that form when a lot of gases and dust come together is called a star cluster. Star clusters can be either open clusters, which are loosely bound and contain young stars, or globular clusters, which are tightly bound and contain older stars.
What are the star systems and clusters?
they collect particals and form stars close together
What does a galaxy include?
global clusters, open clusters and star clusters. (:
Globular clusters usually contain fewer stars than open clusters true or false?
Actually the terms "Globular" and "Open" are not related to the number but the age of the stars. Globlular clusters are many old stars packed in spherical form (they look like hazy mothballs to the naked eye) and "open clusters" are many young stars formed close to each other. The constellation Pleiades is an example of open cluster.
Why do global clusters have fewer heavy elements than open clusters?
Global clusters, or globular clusters, are older, densely packed groups of stars that formed early in the universe's history. They have fewer heavy elements, or metals, because they originated before significant stellar evolution and supernova events that create and distribute these elements. In contrast, open clusters are younger and formed in regions that have already experienced multiple generations of star formation, leading to a higher abundance of heavy elements due to the recycling of materials from previous stars.
How are distances estimated by studying stars and clusters and the galaxy?
the space from the planet the stars or clusters
The brightest stars in aging globular clusters will be?
The hottest stars. Generally, globular clusters contain mainly old stars, population II stars
Which stars in globular clusters are believed to be examples of mergers?
Blue straggler stars in globular clusters are believed to be examples of mergers. These stars are thought to form from the merging of two smaller stars or from the collision and merger of two stars in a binary system, leading to them appearing brighter and bluer than other stars in the cluster.
What are billions of stars held together by gravitational attraction?
They form galaxies, galactic clusters, and galactic superclusters.
What are clusters of stars that all appear to lie at the same distance from us?
Clusters of stars that all appear to lie at the same distance from us are called star clusters. There are two main types: open clusters, which contain young stars and are loosely bound together, and globular clusters, which contain older stars and are tightly packed.
What are clusters of stars?
galaxies
