What are two types of star clusters?
two types of star clusters are Open clusters and globular clusters
What is a group that is closer together than the surrounding stars is called an?
A group of stars that are closer together than the surrounding stars is called a star cluster. Star clusters can be divided into two main types: open clusters and globular clusters, with open clusters being more loosely bound than globular clusters.
Are fewer new stars found in open clusters than globular clusters?
Yes, fewer new stars are typically found in open clusters compared to globular clusters. Open clusters, which are younger and contain loosely bound groups of stars, still have ongoing star formation due to their relatively rich gas and dust content. In contrast, globular clusters are much older and generally lack the necessary material for new star formation, as they are composed of older, tightly bound stars with minimal gas and dust. Consequently, new star formation is rare in globular clusters.
How are star clusters distributed in the sky?
Open clusters lie along the Milky Way and half of the globular clusters are in or near the constellation Sagittarius.
Where are open clusters located?
Open clusters are typically found in the galactic disk of spiral galaxies, including our Milky Way. They are often situated in regions of active star formation, such as spiral arms, where gas and dust are abundant. Open clusters can also be located in the halo of the galaxy, but they are less common there compared to globular clusters. Their relatively young age and loose structure distinguish them from the more densely packed globular clusters.
What are the key differences between open and globular clusters in terms of their structure and composition?
Open clusters are loosely bound groups of young stars that are found in the disk of a galaxy, while globular clusters are tightly packed groups of old stars that are found in the halo of a galaxy. Open clusters have fewer stars and are more spread out, while globular clusters have many more stars and are more densely packed. In terms of composition, open clusters contain mostly young, hot stars with higher metal content, while globular clusters contain mostly old, cool stars with lower metal content.
Are there any clusters on the Andromeda?
Any major galaxy has LOTS of star clusters, including globular clusters, if that's what you mean.
What is the name of a group of 1000 stars?
Constellation or "asterism". The difference is that "constellations" are officially recognized by the International Astronomical Union, while an "asterism" is any other pattern or grouping of stars.
What type of star clusters has the greatest percentage of old stars?
a globular cluster
What is a huge star group called when it rotates around a common center?
A huge star group that rotates around a common center is called a star cluster. Star clusters can be classified into two main types: globular clusters, which are tightly packed groups of stars, and open clusters, which are looser groupings of stars.
What are the globular star clusters we observe in the sky members of?
Globular star clusters are members of the Milky Way galaxy. They are dense, spherical collections of stars that orbit the galactic center. These clusters contain thousands to millions of ancient stars and are typically found in the galactic halo.
What are the spherical groups of millions of stars found in the milky way called?
Those are called globular clusters, or star clusters.
