Most stars in spiral galaxies form in regions known as spiral arms, where gas and dust are denser. The gravitational interactions and compressive forces in these areas trigger the collapse of molecular clouds, leading to star formation. The ongoing star formation in these arms contributes to the vibrant, blue appearance characteristic of young, hot stars, while older stars can be found in the galaxy's central bulge and halo. This dynamic process also influences the overall structure and evolution of the galaxy.
What else can I help you with?
The majority of known galaxies are which shape?
The two most common shapes for galaxies are a spiral, or an ellipse (circle or oval). All other shapes are considered uncommon.
What galaxy has the youngest stars?
Most new, young, stars can be found in the arms of spiral galaxies
What is the shape of a Spiral Galaxy?
Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.See related link for a pictorial representation.
How are spiral arms related to the disk?
Spiral arms are prominent features of spiral galaxies and are closely related to the galactic disk, where most of the galaxy's stars, gas, and dust are concentrated. They are formed by the density wave theory, where the gravitational influence of stars and gas creates waves of higher density that propagate through the disk, leading to the formation of stars and maintaining the spiral structure. These arms are not static; they move through the disk as new stars are continuously born and older stars move out of the arms. Thus, spiral arms are dynamic features that reflect the ongoing processes within the galactic disk.
What do people use most iTouches or Galaxys?
Itouch defiantly.
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.
What are the spiral arms the site of?
Spiral arms are parts of galaxies - both the galaxies and their spiral arms are huge, by our everyday standards. Spiral arms basically contain most of what the galaxies contain - including stars, dust, gas.
Is a galaxy shaped like a ball and containing only older stars most likely spiral galaxy?
It ture
A flattened combination of matter containing stars gas and dust in a spiral galaxy can be identified as what?
A flattened combination of matter containing stars, gas, and dust in a spiral galaxy is identified as the galaxy's disk. This disk is where most of the galaxy's star formation occurs and contains the majority of its stars and interstellar material. The spiral arms within the disk are regions of higher density that enhance star formation.
What kind of cluster is a tight group of older stars in the halo of spiral galaxies called?
I think you are describing a "globular cluster", which are associated with older stars by most astronomers.
What is a flattened combination of matter containing stars gas and dust in a spiral galaxy?
A flattened combination of matter containing stars, gas, and dust in a spiral galaxy is known as the galaxy's "disk." This disk structure is characterized by its spiral arms, where star formation occurs, and it contains most of the galaxy's visible matter. The disk is surrounded by a more spherical halo of stars, globular clusters, and dark matter.
In which type of galaxy would you be most likely to observe a massive star supernovae in a giant elliptical galaxy or in a large spiral galaxy?
Large Spiral Galaxy. This is because they contain more of the OB stars that are required for a supernova event. Elliptical galaxies tend to be older and have more low mass stars and are not as common as spiral galaxies. See Link for more information
