The Halo Series
You will need Galactic key and this how to get Galactic key you will need to talk to a Galactic team mate by the Galactic HQ.
In the galactic warehouse to the left of the Galactic HQ
after Halo reach,there is no more In total, there is :Halo 1,Halo 2, Halo 3, Halo ODST, Halo wars and Halo reach
Im not exactly sure what you mean by stars. - In the first Halo: Reach trailer, there were "explosions" by bright outlines that may look like stars. The Explosions are Covenant Antimatter charges exploding or Covenant torpedos (laced plasma with a magentic field). The bright outlines are either the ONI complexs that were destroyed to deny the covenant access, areas already glassed by the covenant, uncovered forerunner structures, or possibly giant military complexs. - In the Halo: Reach World Premiere at the end there were either ONI AA Rockets, escape crafts, ect. If you are talking about the beta im not sure if the stars symbolize anything, sorry if this didn't help much
In the Milky Way galactic halo, orbiting the galactic center in a long elliptical orbit around the galactic center
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.
Globular star clusters are members of the Milky Way galaxy. They are dense, spherical collections of stars that orbit the galactic center. These clusters contain thousands to millions of ancient stars and are typically found in the galactic halo.
The collection of ancient stars found in the center of the Local Group is called the Galactic Halo. The Galactic Halo is a spherical region of space that surrounds the disk of the Milky Way galaxy. It is made up of old, metal-poor stars that are thought to have formed very early in the history of the Milky Way. The Galactic Halo is also home to globular clusters, which are dense groups of hundreds of thousands of stars. The Galactic Halo is thought to be the remnant of a smaller galaxy that merged with the Milky Way billions of years ago. The merger caused the smaller galaxy to be torn apart, and its stars were scattered into the Galactic Halo. The Galactic Halo is a very sparsely populated region of space. The stars are so far apart that they are difficult to see individually with the naked eye. However, the Galactic Halo can be seen in the night sky as a faint glow of light.
Oh, that's a gentle question, friend! Stars aren't forming in the galactic halo mainly because the halo contains older stars and less of the materials needed for new stars to form compared to the galaxy's disk. Remember, even in the stillness of the halo, the universe twinkles with endless possibilities elsewhere!
Galactic rotation curves show that stars orbit the center of galaxies at velocities that do not decrease with distance from the center. This suggests that there is additional unseen mass, or dark matter, distributed throughout the galaxy's extended halo. The presence of dark matter is necessary to provide the gravitational pull required to keep stars at their observed velocities.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
The Milky Way galaxy's galactic halo contains predominantly old stars, globular clusters, and dark matter. It stretches outwards from the disk of the galaxy and contains a sparse population of stars compared to the central regions.
Halo stars are usually very old stars that do no orbit the centre of the Galaxy the same way that our Sun or other stars in a galaxy. Rather, they travel in elliptical orbits, which often take them well outside the plane of the Galaxy.
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.
Stars travel in various ways. On the largest scale, the universe expands, and stars move away from each other. On smaller scales, stars are most often part of galaxies and they orbit the center of the galaxy, while the galaxies themselves often are in orbit around a center of gravity of a galactic cluster.
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.
