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!
What else can I help you with?
What is the collection of ancient stars found in the center of the local group called?
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.
What is found in the Milky Way galaxy's galactic halo?
"The halo primarily contains individual old stars and clusters of old stars ("globular clusters"). It may be over 130,000 light years across. The halo also contains "dark matter," which is material that we cannot see but whose gravitational force can be measured." to shorten the answer - individual stars, clusters, and dark matter.
What motion do stars exhibit in the Milky Way Galaxy?
Stars in the Milky Way Galaxy primarily exhibit orbital motion around the galactic center, following roughly circular or elliptical paths influenced by the galaxy's gravitational forces. This motion is not uniform; stars in the spiral arms tend to move at different speeds compared to those in the galactic halo. Additionally, stars may also exhibit vertical oscillations, moving above and below the galactic plane as they orbit. Overall, the motion of stars contributes to the dynamic structure and evolution of the galaxy.
Are young stars the halo stars?
maybe i dont know it can be make you guess.
What is a halo star?
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.

How do stars in the galactic halo orbit?
They orbit as stars would in any other halo. It is gravity that causes everything to orbit and "spin around" Stars can also orbit around other stars called a binary orbit.

What are the globular star clusters we observe in the sky members of?
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.
Where in space would you look for a globular cluster?
In the Milky Way galactic halo, orbiting the galactic center in a long elliptical orbit around the galactic center
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.
What behavior do galactic rotation curves exhibit to suggest the existence of dark matter in an extended halo?
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.
What can cause a galactic fountain?
A galactic fountain is primarily caused by the combined effects of supernova explosions and stellar winds from massive stars. These energetic events eject gas and dust from the galactic disk into the galaxy's halo, creating outflows that can rise and fall due to gravitational forces and galactic dynamics. Additionally, the cooling and subsequent condensation of the ejected material can lead to the formation of new stars, contributing to the cycle of star formation within the galaxy.

What has the author Geoffrey Stuart Burks written?

What is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars called?
The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
Why are some stars in the middle of galaxies and are on the outside?
Stars in the middle of galaxies are usually found in the galactic disk, where there is a higher concentration of gas and dust that is conducive for star formation. Stars on the outside of galaxies are often located in the galactic halo, which is a more diffuse region that contains older stars and is further away from the dense center of the galaxy. The distribution of stars within a galaxy is influenced by factors such as gravitational interactions and the history of star formation in that region.
