Spiral galaxy.
Clouds of gas and dust in which stars form are called nebulae. These regions of space are where the raw materials for star formation gather and eventually collapse under their own gravity to give birth to new stars.
This disk of dust and gas that formed the sun and planets is called the solar nebula. It is a rotating cloud of gas and dust left over from the formation of a star. Over time, the particles in the nebula began to clump together and form planetesimals, eventually leading to the formation of planets.
The dust and gas located between stars in a galaxy is called the interstellar medium (ISM). This material plays a crucial role in the formation of new stars and planets within the galaxy.
Stars. That is how stars are formed. They form from nebulae.
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.
No. The clouds of gas and dust are called nebulae. A quasar is a disk of superheated matter falling into an enormous black hole.
Yes, the solar system including our Sun and planets is believed to have formed from a large disk of gas and dust called a proto-disk or proto-solar disk, due to gravitational effects. It is currently thought that several stars formed from the same cloud as our Sun.
Molecular clouds
Yes, planets are formed from the same clouds of gas and dust as stars. These clouds are called molecular clouds, and they consist mostly of hydrogen and helium along with other elements. As the cloud collapses under gravity to form a star, leftover material congregates to form planets and other smaller bodies in the newly formed solar system.
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.
The gases and dust from which stars condense are called cosmic dust or particles.
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.
A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.
It is called a stellar nebula.
Which of the following statements correctly summarize key differences between the disk and the halo?Answer:Clusters of young stars are found only in the disk.Stars in the disk all orbit in the same direction and nearly the same plane, while halo stars have more randomly oriented orbits.Gas and dust are abundant in the disk but not in the halo.Disk stars come in a broad range of masses and colors, while halo stars are mostly of low mass and red.
