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.
What galaxy has arms where lots of new stars are being born?
The Milky Way galaxy has spiral arms where a lot of new stars are being born, including the Orion Arm where our solar system is located. These spiral arms are regions of higher density that promote the formation of new stars due to gravitational interactions between gas and dust.
What are the arms of a spiral galaxy?
They are objects that are confined to the arms of a galaxy, i.e. objects that only exist within the spiral arms, and are not found (except very rarely) outside of spiral arms. Examples of tracers are structures to do with star formation, like for example open star clusters, giant molecular clouds or supernova remnants.
What are long arm chromosomes is called?
Long arm chromosomes are called q arms, while short arm chromosomes are called p arms. These arms are distinguished based on their relative length and position in the chromosome.
What do brittle stars look like?
Brittle stars have a central disc with five arms that are long, thin, and flexible. They come in various colors like brown, red, or gray and often have spines or tubercles on their arms and disc. Their arms are used for movement and feeding, while the central disc houses vital organs.
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 galaxie has a thick center and flattened arms?
The galaxy you are describing is a spiral galaxy. These galaxies typically have a dense, thick center known as the bulge, composed of stars and gas, along with flattened arms that extend outward, where stars, dust, and gas are concentrated. The Milky Way is a prime example of a spiral galaxy with these characteristics.
What is a galaxy arms coming from the center like a pinwheel?
A galaxy with arms extending from its center like a pinwheel is typically classified as a spiral galaxy. These arms are regions of higher density where stars, gas, and dust are concentrated, often resulting in active star formation. The spiral structure is maintained by the galaxy's rotation and gravitational interactions, creating a dynamic and visually striking appearance. Prominent examples of spiral galaxies include the Milky Way and the Andromeda Galaxy.
What is the angle between two arms of a star?
Stars do not have arms.
What is the difference between the brittle stars and the basket stars?
Brittle stars have long, flexible arms that help them move quickly, while basket stars have branched arms that are used for filter feeding. Brittle stars typically have five arms, while basket stars can have 10 or more arms that branch out extensively. Additionally, basket stars are usually found in deeper waters compared to brittle stars.
How are barred spiral galaxy different from spiral galaxy?
An ordinary spiral galaxy has spiral arms coming out of the core. In a barred galaxy, the central area consists of a bar of stars and the spiral arms are attached to the ends of the bar.
How do brittle stars get food?
With there arms.
Why do new stars form in the arms of a spiral galaxy and not in the central bulge?
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
In which types of galaxies is concentration of stars more centrally located?
The concentration of stars is typically more centrally located in elliptical galaxies compared to spiral galaxies. Elliptical galaxies have a more concentrated spheroidal shape with stars distributed densely in the center, while spiral galaxies have a more spread-out disk structure with stars distributed along spiral arms.
Who said The English are coming in the Revolutionary War?

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.
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.
