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.

What is the difference between disk stars and halo stars?
Disk stars are typically younger and found in the disk of a galaxy, where active star formation occurs. Halo stars, on the other hand, are older and generally located in the outer regions of a galaxy's halo. Halo stars formed early in a galaxy's history and are not actively producing new stars.
How are stars in the disk of the milky way different from stars in the bulge or halo?
The ones in the bulge or halo are older star, the ones in the disk are younger.
The Population II stars in your galaxy are located a in the halo but not in the disk b in neither the halo nor the disk c in both the halo and the disk d in the disk but n?

What is the difference between halo 3 and halo odst disk 2?
The Halo Odst Disk 2 comes with all maps (Plus 3 extra), and the ordinary halo 3 disk comes with no added map packs, so you don't have another 12 maps.
What do halo stars do differently from disk stars?
Halo stars are older and have lower metallicity compared to disk stars. They often have orbits that take them further away from the plane of the galaxy and they are thought to have formed through different mechanisms, such as mergers with other galaxies or early galactic collapse.
Would you expect stars in the halo of the galaxy to have planets?
It is less likely for stars in the halo of a galaxy to have planets compared to stars in the disk of the galaxy. This is because the halo contains older stars with fewer heavy elements necessary for planet formation. However, some planets could still exist around halo stars, but they would be rare.
What is the difference between halo 2 and halo 2 1.5?
there is no difference
Name four different objects you can find in our galaxy?
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.
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.
How do spirals form?
Spiral galaxies form from the collapse of a protogalactic cloud. Spiral galaxies consist of three components: a rotating disk, a bulge and a halo. Spiral galaxies, like the Milky Way, owe their shape to stars inside the protogalaxy developing at different intervals. The gas between forming stars continues to be compressed, and the resulting gravitational differences manhandle the protogalaxy's stars, dust and gas. When the protogalactic cloud collapses, the stars in the bulge and halo form first. These stars have rather random orbits around the galactic center. The galactic center probably contains a supermassive black hole, which likely exerts some gravitational influence on the formation of a spiral galaxy. The remainder of the cloud forms a disk due to the conservation of angular momentum (the same effect as the spinning up of the dancer when she pulls her arms inside). This motion forces everything into a rotating disk, and additional differences in gravity build the spiral arms. Oppositely, when a protogalaxy's stars develop at the same time, you have an elliptical galaxy on your hands. The stars in the disk form later and thus the disk population of stars are younger than those in the bulge and the halo. Further, the stars in the disk rotate around the center of the galaxy in a collective, well defined way unlike the stars in the bulge and halo.
