What else can I help you with?
How are the stars distributed within this kind of galaxy.?
The center of the elliptical galaxy is very dense with many stars, and density decreases farther out.
What is a cluster of tightly packed of older stars called?
A cluster of tightly packed older stars is called a globular cluster. These clusters can contain thousands to millions of stars, and are usually found in the outer regions of galaxies.
Which type of galaxy mostly consists of a collection of older red stars that are located in the center with blue and white stars located in the outer regions?
Elliptical galaxies mostly consist of a collection of older red stars in the center, with blue and white stars located in the outer regions. This is because elliptical galaxies have a smooth, featureless appearance and are dominated by older stellar populations in their central regions.
Why are older stars located at the center of a spiral galaxy while younger stars make up arms of a spiral galaxy?
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.
What is a tight group of older stars located in the halo of spiral galaxies is?
That is a globular cluster. These clusters are spherical collections of stars that orbit around the center of a galaxy in its halo. They are typically made up of thousands to millions of stars that are much older than the stars found in the disk of the galaxy.
Why are older stars located at the center of the spiral Galaxy while younger stars make up the arms of a spiral Galaxy?
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.
What are straight branches of stars projecting from the center of galaxy?
The straight branches of stars projecting from the center of a galaxy are known as stellar streams. These streams are formed when a smaller galaxy or star cluster orbits around a larger galaxy, and its stars are pulled into a long tail-like structure due to the larger galaxy's gravity. Stellar streams can provide valuable insights into the history and dynamics of galaxies.
What shape of galaxy is small has older stars very little dust and a bright center?
The galaxy you are describing is most likely an elliptical galaxy. Elliptical galaxies are typically smaller than spiral galaxies, contain older stars, and have very little interstellar dust and gas, which contributes to their lack of new star formation. Their bright centers are a result of the dense concentration of stars, particularly older red stars, in the core.
What is a group of stars with black hole in center?
A galaxy.
What type of galaxy has giant bright new stars around the edges and older stars in the middle?
a spiral galaxy like the milky way
What are young galaxy stars that have giant black holes at the center?
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
A galaxy with a bulge at its center and spiral arms?
This type of galaxy is categorized as a spiral galaxy. The bulge at the center contains older stars, while the spiral arms consist of younger stars and gas and dust regions where new star formation occurs. The Milky Way is an example of a galaxy with a bulge and spiral arms.
